The Labmart LMPH10H Benchtop pH / mV / °C Meter is a laboratory-grade multipurpose meter designed for accurate measurement of pH, millivolts (mV), and temperature. It features a large backlit LCD, up to 3-point calibration with automatic buffer recognition, automatic temperature compensation, electrode diagnosis, automatic endpoint detection, USB connectivity, and memory for up to 100 readings. 

Product Overview

The Labmart LMPH10H Benchtop pH Meter is a benchtop analytical instrument for routine and laboratory measurement of pH, mV and temperature. The instrument provides a pH measuring range of -2.00 to 16.00 pH, with 0.01 pH resolution and ±0.01 pH accuracy. Temperature can be measured from 0 to 105°C.

The meter incorporates up to 3-point push-button calibration, automatic recognition of USA and NIST buffer standards, pH slope display, automatic temperature compensation (ATC), automatic endpoint detection and configurable measurement settings. Its large 125 × 100 mm white-backlit LCD provides measurement information and operational prompts for convenient laboratory use.
