Benchtop Multi-parameter Water Quality Meter LMPWM-A40

Description :

Benchtop Multi-parameter Water Quality Meter LMPWM-A40 with 7 inch TFT display measures pH, mV, relative mV, water hardness, and temperature and Ion concentration of the sample. With expanded memory, it stores and recalls up to 1000 readings. Calibration due reminder informs operator to calibrate the meter regularly.
