Portable pH Meter

Description :

The ST423 is a compact battery operated instrument designed to give the same reliability and accuracy in the field as you demand on the laboratory bench.

Simple traditional rotary controls ensure that the ST423 can be used by untrained operators to give temperature compensated results in seconds.

The ST423 pH Meter is a general purpose portable pH/mV/ Temperature meter. One or two point calibration is possible and the BNC connector allows the meter to be used with any of the impressive range of combination or half-cell pH electrodes from Dintok directION.

Manual and Automatic Temperature Compensation (ATC) are standard features. The clear LCD display allows the measurement of pH , mV and temperature. For ISE work the ST423 can be used in the mV mode. However it is recommended that accurate ion analysis be carried out using the ST451 (mV mode +/- 0.1mV) or the ST867P direct concentration Ion meter.

The ST423/Kit is ideal for field work with a robust Carry case, electrode, ATC probe, battery and calibration solutions.
