Product Description

The LABMAN LMMP32 is a benchtop water quality multiparameter meter that measures pH, ORP, ion concentration, conductivity, TDS, salinity, resistivity and dissolved oxygen. It includes a DO electrode, supports up to 5-point calibration, stores 500 data sets and has a built-in real-time clock for GLP data stamping.

Key features

  • Eight measurement modes: pH, ORP, ion, conductivity, TDS, salinity, resistivity and dissolved oxygen
  • DO electrode, pH electrode and conductivity cell supplied
  • pH mode: up to 5-point calibration with auto buffer recognition (USA, DIN, NIST or user-defined)
  • Adjustable TDS factor, cell constant, temperature coefficient and normalization temperature (20°C or 25°C); linear or pure water compensation
  • Practical salinity (PSU) or sea water standard (ppt) in salinity mode
  • Electrode slope shown after calibration; calibration due reminder; automatic endpoint hold
  • Memory of 500 readings; built-in real-time clock for GLP; optional fluoride and nitrate ISE and ORP electrode
