Hanna Ph meter help

[ShadowKill22]

hey guys i have the hanna hi98130 its the same as the 98129 just it reads in ppts but anyway i am trying to calibrate my ph and when it tells me to use the 7.01 buffer i put it in gh 7.0 buffer but nothing happens it just sits there and eventually hits the 8 min turn off point any suggestions? Thanks in advance

ps: i have stuck it in the 4.01 buffer when it asked for 7.01 and it calibrated to it and read 7 in the 4 so i know its calibrating.

Hhhmm.... is the probe completely immersed in the 7.0 solution? I had a problem with mine, then I discovered I had broken the glass probe. Then I had another problem and after cleaning the probes I was able to calibrate like normal. Another time I had a problem I think my 7.0 solution had become dirty or something and it didn't like it, so I used a new bottle and it worked fine.

Clean your probes,check batt status,then put probe in sol. . If it is in the 8's usually the probe is contaminated. I soak mine in an acidic solution for ten min then rinse well. If it does not work you might need a new pH probe. If mine dries out more then 2 times it will get that way. JK

Thanks everyone I ended up leaving it in some storage solution over night and then retried this morning and it calibrated just fine i think it might have just been dry (first time its ever been used)

I do have another question i cant get my ppt to cal I have the 1500ppm solution and have my conversion factor to .70 but it will not calibrate any ideas? do i need a different calibration solution for the hi 98130?

:mysterymachine:

Now I can't remember what the solution is, but I personally use the 1413 (or whatever it is) NaCl, again if I recollect, solution, as it's what is instructed no matter what conversion factor I use. Everything's downstairs. What ppm calibration solution (ppt is a pretty fine resolution, if that's its accuracy, well, damn) do the instructions say to use?

I swear I think my pen is the HI 98130. If we're using the same meters, you're using the wrong ppm calibration solution, and Googling, I'm pretty sure we're using the same meter. It measures in microSeimens, which can be converted to EC (using a .5 conversion makes it easy, as 500ppm = 1.0EC), ppm (parts per million, not trillion) and pH as well as temperature.

Use either cleaning/conditioning or 4.01 calibration solution to store the meter.

***Edit: Get this solution: HI 7031 1413 MicroSeimens ppm calibration solution.

I got one of the meters that came with PPT as well, pretty dumb if you ask me.

BTW Seamaiden your wrong when you say to convert mS/cm (millisiemens) using the .5 conversion to get EC. The .5 or .7 conversion is used to get the PPM since PPM is the result of that conversion. Thats why no one should use PPM's unless you state your conversion (ie .5 or .7). Millisiemens can be converted to EC or uS/cm (microsiemens) by multiplying by 1000. The mS/cm, uS/cm, EC have the same reading you just need to move the decimal place over. Also never heard of using 4.01 calibration solution as storage solution, I've always read and been told to use 7.01 calibration solution for storage.

I looked up the manual for your meter and it appears that you need the 12.88 mS/cm solution to calibrate your meter (same as my old stick meter). You can see this by holding your on button after your meter is already on and cycling through those options, you'll come to a reading that will state what calibration solution you need for the EC. Which should be 12.88 mS/cm solution, if not, whatever number that shows go and get that calibration solution.

BTW I don't think any of Hanna's older ph meters will calibrate using 7.01 solution, I know my older units don't. Luckily the new model that came out this year works like a charm for ec and ph since they are manually calibrated by a dial on the bottom :party0045:.

You do not have to use the 4.01 or the 7.01 either. You can use just one of those if you just have one.
Also a PH reader will not go in the Hundreths either. mine only reads 7.0 when I put it in the testing solution. Using both of the PH calibrating solutions only makes it super accurate.
I have gone with using just the 7.01 ph calibrating solution for a while when I did get the 4.01 Ph CS it was dead on at 4 ph when I put it in the 4.01 PH solution.

There are 2 different PPM numbered solutions to calibrate by.

 

[ShadowKill22]

it looks like i am going to have to pick up some new calibration solution damn the one i just got was 20 bucks :(
thanks guys and i was trying to use the .7 conversion factor and a 1.9 beta and my meter is ppt and ms so
ppt *1000 = ppm :p

Smokey, these meters measure pH to two decimal points, that's hundredths, right?

That wasn't what I said, I said using a .5 conversion factor makes calculating EC easy (easier). While I can spell and speak very well, I am mathematically declined and I have to make those things as easy as possible or I'd never get anything done with my girls.

Shadow, here's the manual for the HI98130, examine it carefully, because in that manual are the instructions for all sorts of things like precisely which calibration solutions are to be used. It appears that I was sold the wrong calibration solution, though, again, by the manual, I can't determine the difference between the HI 98129 and the HI 98130 meters, and I know mine's been calibrating off the 1413 solution.

The numbers for the solutions to be used that are in the manual are the following:
HI 7030 = 12.88 solution tokin is talking about
HI 70038 = (6.44 ppt; CONV=0.5 or 9.02 ppt; CONV=0.7)

Christ, if it measures in ppt's, but it's only going to indicate via ppm's... never mind, it's enough figuring out conversion factors, let alone whether or not it's measuring in parts per trillion or parts per million. I think I need to call Hanna.

The hi98130 reads in parts per trillion and the hi 98129 reads in parts per million so the 98129 should be more on the money because we have to multiply our ppt by 1000 to get ppms of the solution.

It says in the manual that the hi98129 needs the hi7031(1413 us/cm) and the hi98130 needs the hi7030(12.88 ms/cm) to calibrate the tds/ec.
i bought the wrong one :(

going to pick up the new stuff now hope my local hydro store has it in stock. Thanks everyone

I have the ppm/ph combo 9813-0 and Ive been having problems myself. I bought the damned 10 dollar shipped 1500 ppm solution from GH and the probe wont read it for shit, I know my probe is clean and all that jazz but for some reason it wont read the ppms unless I use a massive amount of solution in a plastic container. I really need to figure out how to make my own solution so I dont have to keep buying this shit haha best of luck to you brother man, hope your ph pen probs are over!

The way you worded that was funky just wanted to clarify any confusing details.

I said using a .5 conversion factor makes calculating EC easy (easier).

Let me rephrase that for you, "Using a .5 conversion factor makes calculating PPM easier." EC is not the result of a conversion.

 

[Seamaiden]

It has to be converted somehow, or people would be talking about EC readings in the hundreds and thousands, not single digits with decimals, no? By that I mean, when I'm looking at the microSeimens measurement it's giving me, it's a four digit number with no decimal point, such as 1362us (I don't know how to make the symbol), so it doesn't look anything like what people are talking about when they say they're running a 1.8EC, or girls did fine at a 2.0EC. How'd they get there? If they read it directly off the meter then I've clearly missed something in setting the thing up, and would very much appreciate any other information on that stuff that could be provided. I thought I'd gone over the instructions very carefully.

PPMs I can wrap my head around, but combining organics with chemical salts the way I am, I also know that readings tend to be funky. I still keep notes, I just don't note all the different measurements.

 

[tokinsmokin]

Actually the number your talking about is the same reading as EC. Its just that most meters come with the measurement mS/cm (milliSiemens) which is why you often see people talk about EC being referred to as 2.0. Where as EC is actually 2.0*1000=2000EC. Either way though its the same number just different decimal place unlike converting to ppm.

What your stating is that your finding out the EC by using the .5 conversion, and what I'm saying is thats wrong! The .5 conversion that your talking about is how you convert (EC, microSiemens) to PPM's. An example would be your meter reads 1362 uS/cm well that number is the same for EC (1362) and could be converted to mS/cm (milliSiemens) by dividing by 1000, 1362/1000=1.362 mS/cm, which is the unit that you will most often see on forums. Now where the .5 conversion factor comes in is when you change your uS/cm (microsiemens) to PPM, example 1362 uS/cm multiply that by .5 or .7 conversion factor depending on the brand of your meter and you will get 681 PPM with .5 conversion or 953 PPM with the .7 conversion.

So don't wrap your head around PPM's because you should be using EC since the conversion to PPM's isn't a perfect calculation, and who wants to use a measurement that has different conversions?

Sorry can't pm you yet even though I've already typed up what I was going to respond to you. Can't find out how many posts you need either, I'm guessing its probably 50.

 

[Seamaiden]

I can't remember how many posts you need, and I hadn't paid any attention to how many you have. But! I've begun taking readings using uS, since I haven't grasped how using one conversion factor over another can so significantly change the total/actual ppm of a solution.
