Benchtop Multi-parameter Water Quality Meter LMPWM-A32 Catalog

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.

Help message as an operational guide, helps users for quick access to the parameters
Reset function automatically resumes all the setting back to factory default options
Store data is transferrable into computer via USB communication interface
pH mode 1-5 points push button calibration to automatically identify pH buffer
Convenient to select pH buffer standard (USA/NIST/DIN) or custom
Automatic electrode slope display helps operator whether to replace the sensor
Conductivity mode 1-5 point for calibration with automatically identification of calibration solutions
Can select cell constant (0.1/1/10) and normalization temperature (20°C or 25°C)
TDS conversion factor, seawater, practical salinity measurements mode to meet different water quality measurement requirements
Linear or pure water compensation improves the measurement accuracy
Dissolved oxygen mode 1-2 points calibration using the air-sealed water & zero oxygen solution
Manual salinity & barometric pressure compensation for accurate readings
