never heard of it, seems pretty basic though i am sure it will work fine. its good it has the temperature too

the instructions are on the weird side... it says to calibrate the ph in a 6.86 standard buffer solution

also for EC calibration says to immerse in 12.88ec solution

and what does this damn thing mean by

"rinse electrode with distilled water, and SUCK IT with filter paper???" i guess wipe it off.... and what filter paper?

lol from what i've always seen people always calibrated their rodes with 7.0 or 9.0 never 6.86.. please tell me its cool or is this thing going to be a bitch to calibrate?

your main concern with these 24-7 meters is to be very carfull with the ph probe!! there "very fragile glass bulbs,"will im sure most probes are also? im assuming they mean after rinsing probe "gently" lay a tissue of some sort, on top and it will suck up the liquid?
bro im just trying to save you some $ and a possible headache from breaking it and having 2 buy a new replacement probe!! i broke 2 already, very very easy, and at 65$ a peace give or take, there not cheap!! good
luck bro youll enjoy the ease of it.

same one i have, i love it, calibrates very easy and hold calibration

as far as 6.86 goes, ive always seen 7.01? and or 4.0? soo... its not too far off from
7. u should be alright man, jmho, stay safe bro.

well hell yeah then i did good i bought it for 120 shipping included.. thx guys im about to post a update on the clone in the infirmary.. check it out!

well fuck.. my rods are not glass their like plastic.. check em out now what you guys think....

Im sure its fine. Did it come with calabration solution? Every mfg has their own calibration shiz, don't worry about it :)

and nope it didnt come with the solution... figures.. and maybe theirs glass inside i dont want to try and open it to find out lol..

Just make sure you take those caps off the probes BEFORE you use it. ;)

I have an identical meter with a different name on it...same probes.
Instructions were a JOKE. First experience with them. Didn't realize that
those were caps on the ends... Thought my PH was 9.2... DOH!!!
All is well now. My tap water isn't actually all that bad!

I just laughed so hard I snorted.

That meter looks sick, I want one. I think that filter paper will leave no lint, that may be why they recommend it. Have you looked around for a 6.86 calibration solution yet?

The use of pH 6.86 buffer to calibrate the offset of pH meters is a quite recent practice. This is due to the fact that even though this buffer offers higher accuracy, it has been know for not being very stable. In addition, the introduction of microprocessors in pH meters, that perform automatic buffer recognition, has eliminated calibration trimmers and screwdrivers. Although, in many cases, this first generation of microprocessor was unable to distinguish between pH 6.86 and pH 7.01. As a consequence, the first was abandoned in favor of the second.
Modern pH meters from HANNA® have brought back this calibration value. Our latest portable and bench microprocessor instruments, may now be calibrated both with pH 6.86 and pH 7.01.
The HANNA® range of pH 6.86 buffer solutions has been expanded and stability has been improved to match the stability of pH 7.
I bought a Hanna pH meter late last year, and it's a 7.01-4.01 calibrated meter. Sure would be nice to not have to buy two solutions and eliminate an entire step.

What did you pay for it and where did you get it? Did you check out any reviews and all of that before you bought it (I can't help myself, I have to do that every time). I can't seem to enlarge your attachments so I can get a better look. But I need to get a meter that will measure EC/TDS/ppm.

Something else interesting on pH calibration.

I bought the same meter on Ebay its a cheap knock off but it worked well for about 1 year for me. Then the PPM stopped working and would not work plugged in ( worked with batteries ).
