2 LMPWM-A Series Benchtop multi-parameter water quality meter LMPWM-A series is comes with different measurement modes for quality and testing of water on different parameters. It measures ph, Conductivity, TDS, Dissolved oxygen, Salinity content from the test sample. It stores and recalls up to 00 sets of data. Calibration due reminder informs operator to calibrate the meter regularly. Common 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 00 readings 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 - 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/TDS/ Salinity/Resistivity mode - point for calibration with automatically identification of calibration solutions Can select cell constant (0.//0) and normalization temperature (0 C or 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 (Only for LMPWM-A) - points calibration using the air-sealed water & zero oxygen solution Manual salinity & barometric pressure compensation for accurate readings Applications Used for quality checking of water on different parameters across research, QC labs, water management plants and others production units.
