Benchtop multi-parameter water quality meter LMPWM-A31 comes with different measurement modes for quality testing of water on different parameters. It measures pH, conductivity, TDS, salinity, and resistivity content from the test sample. It stores and recalls up to 500 sets of data. Calibration due reminder informs the operator to calibrate the meter regularly.

Features:

• Stability indicator displays the status of current measurement
• Auto hold function freezes stable, final readings for better viewing and recording
• Manual temperature calibration to rectify the deviations in temperature
• Automatic temperature compensation for accurate measured value over the entire range
• Selectable temperature units (°C or °F) for different application requirements
• Expanded memory stores and recalls up to 500 readings
• Help message as an operational guide, helps users for quick access to the parameters
• Reset function automatically resumes all the settings back to factory default options
• Store data is transferrable into the 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 the operator know when to replace the sensor
• Conductivity/TDS/Salinity/Resistivity mode: 1-5 points for calibration with automatic 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
