About this product

The Checker Plus pH Meter provides rapid pH readings from 0 to 14 pH with a resolution of 0.01pH. Its slimline design means that it is equally useful for testing liquids in test tubes and beakers as well as for taking into the field. The easy to read LCD screen shows the pH value and also indicates the buffers used for calibration. The calibration process uses two buffers and buffers are automatically recognised. The electrode unscrews from the body of the meter making it easy to change when required.

The Checker Plus uses a CR2032 lithium-ion battery (included) which will power the unit for up to 1000 hours. An auto-off features ensures that the meter shuts off after eight minutes of non-use. The battery compartment is easily accessible when the battery does eventually need changing. 

This meter requires two buffers for calibration. Please see the accessories for bottles and sachets of pH buffers.
