Greisinger GMH 3531 pH Meter

The GMH 3531 is a handheld meter that is designed to carry out measurements of pH levels, Redox (ORP), rH levels, and temperature. The meter carries out standard or mVH measurements in ORP mode that allow for automatic conversion to hydrogen system electrodes. Calculation of the rH value is by means of an ORP measurement and by manual entry of pH value or use of previously recorded pH measurement. There is 1, 2 or 3-point calibration with either a supplied buffer, DIN 19266 buffer or manual buffer selection.

The GMH 3531 has a display, consisting of two 4-digit LCDs (12.4 and 7mm high), that is easy to read and provides clear and concise instructions and readings. An additional feature of this meter is a calibration interval notice, where the device gives notice of the need for calibration after a selectable time period of 1 to 365 days or can be set to inactive.
