Description

PH METER Can bring scientists accurate pH value to study things in the laboratory, and also widely used in different places such as hydroponic, camping, hot springs, drinking water and so on. The digital pH tester for water calibration :.Dissolve each buffer into 250 ml of distilled water (under the temperature of 25) , the first put into 6.86 solution for 5 seconds, and release 6.86 until the display stops flashing,then dry the pH meter for water with filter paper. .The same as above put the water quality tester into pH4.00 solution. .If the water testers for drinking water incorrect, please repeat the calibrate. .If approximate pH of your test solution is known to be above 7.0, calibrate the meter using 6.86 and 9.18 solution. The third step is the calibration method for 9.18 point. Note: After cleaning the electrode of the pH water tester, you can only use filter paper to dry it. Do not use the fabric to pick up the electrode to generate static charge and cause wrong reading. The medicine powder is kept for two years, and the calibration solution can be reused for six months without contamination.

After calibrating the pH meter with the included solution, the measurements seem to drift off immediately.It's ok for my purpose, where I don't use it that often and I can do a quick cal before using it, it'd be very bad for anyone who wants to use it more often. Even a couple minutes after doing the cal, the values would be off by a lot when measuring the cal solution again.Meter would not calibrate. Would not recommend. Some packaging indication that meter was used. Not happy with purchaseYou can trust this product, we have bought 2 of them so far and will buy the same when we need to.Wouldn’t calibrate to the ph 4 standard right out of the box, it’s worth it to spend a little more money on a better product, I bought one made by doctor meter for around 30 dollars and it works much better, if you don’t want to spend that much I’d go with pH strips, this meter was more or less useless in my experiencethe meter will not calibrate and is totally inaccurate.Seems accurate and easy to use. I use it dailyNo 9.18 that it says is needed to calabrate it. I thought it still might work just not as accurate but it wouldn't even work for the first step! It only reads 0 no matter what! I wish it would of worked one time at least. Useless! Money gone!Couldn’t calibrate
