pH pocket meter with ISFET sensor
Distributed by MMM Tech Support
Description
These models are waterproof, durable pocket meters for pH and temperature with a glass-free ISFET pH sensor and replaceable reference electrode. Only the smallest amount of sample is required for a measurement, a single drop is sufficient. The pH pocket meter model PH712 / PH922 are also suitable for direct measurement of pH in soils and substrates and other pasty substances.
ISFETs are very accurate and require significantly less recalibration compared to conventional glass pH electrodes. ISFETs for pH are particularly fast-reacting, unbreakable, maintenance-free and are stored dry. In addition, a 1-point calibration is often sufficient, since ISFETs usually only require recalibration of the offset, but not of the slope.
