pHep®+ Pocket pH Tester with 0.01 pH Resolution - $40

[Hidden426]

Great PH tester. I am breaking down my setup and have no need for any of this anymore.

I have one of the two buffering solutions required to recalibrate. I last used it a month ago and it was dead on so I don't think it need a recalibration but if I were to buy something from here I would want to recalibrate to be sure.

The manual says this is under care and maintenance:

To obtain the highest accuracy for measurements it is important to follow these tips:• Calibration is only as good as the buffers being used. The pH buffers value changeover time once the sachets are opened. Fresh buffer should be used for eachcalibration.• The electrode should be rinsed with purified water each time before placing inbuffer or sample to be tested.• When the meter is not in use it is important to add several drops of storage solutionto a sponge in the protective cap to keep the electrode hydrated. If storagesolution is not available, then pH 4.01 or pH 7.01 buffer can be used.• For improved accuracy it is recommended to calibrate in two buffers. It is importantto use buffers that bracket the expected value of the sample to be tested. Forexample, if the expected value is pH 8, the meter should be calibrated usingpH 7.01 and pH 10.01 buffers.
