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.
I just laughed so hard I snorted.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?
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.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.
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!
