The LABMAN LMMP30 is a benchtop water quality multiparameter meter that measures pH (−2.000 to 20.000, ±0.002 pH), ORP, conductivity (0–200 mS/cm), TDS, salinity and resistivity. It supports up to 5-point calibration for pH and conductivity, stores 500 data sets and has a built-in real-time clock for GLP data stamping.
Key features
- Six measurement modes: pH, ORP, conductivity, TDS, salinity and resistivity
- pH mode: up to 5-point push-button calibration with auto buffer recognition (USA, DIN, NIST or user-defined)
- Conductivity / TDS / salinity / resistivity mode: up to 5-point calibration with adjustable TDS factor, cell constant, temperature coefficient and normalization temperature (20°C or 25°C)
- Linear or pure water temperature compensation; practical salinity (PSU) or sea water standard (ppt)
- Electrode slope shown after calibration; calibration due reminder
- Automatic endpoint function freezes stable readings; help messages guide operation
- Memory of 500 readings; built-in real-time clock stamps data to meet GLP standards
