This is a simple pen type meter supplied brand new in a plastic box complete with a calibration adjusting screw driver.

This test meter does require the sensor to be dipped in storage solution/water for 40mins prior to use, (as do all pH meters).

A pH meter is very different from a TDS/EC meter and does require the use of a storage solution to maintain the efficiency of the ph electrode that is in the tip of the device. Also it is important that the device is calibrated regularly with calibration solution. We do recommend that you calibrate your meter close to the range you wish to use it in, for most customers this will be at 7.0 pH, but it is pointless calibrating at 4.0 then wishing the meter to be accurate at 7.0 pH.
