Portable pH Meter LMPH-403

Portable pH Meter LMPH-403

Portable pH Meter LMPH-403 is a rugged device that can monitor pH, mV, relative mV, ion concentration and temperature when paired with the appropriate probe. It is an excellent meter for a variety of applications and advanced pH analysis in the field. Calibration can be performed up to 5 points, and 500 data point sets can be stored. Calibration and data logs can be easily transferred via USB. A custom LCD displays the parameters operating in the 0 - 100°C temperature range.
