Benchtop Multi-parameter Water Quality Meter LMPWM-A32

Overview

Benchtop multi-parameter water quality meter LMPWM-A32 comes with different measurement modes for quality and testing of water on different parameters. It measures pH, Conductivity, Dissolved oxygen, content from the test sample. It stores and recalls up to 500 sets of data. Calibration due reminder informs operator to calibrate the meter regularly.
