Overview

Portable pH Meter LMPH-401 is a versatile device that can monitor pH, mV and temperature when paired with the respective probe. It is an ideal meter for a wide range of applications and advanced pH analysis in the field. Performs up to a 3 points calibration and stores 100 data point sets and easily transfer calibration and data logs via USB. The parameters operating within 0 - 105°C temperature range are displayed on a custom LCD.
