Product Description

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

Frequently asked questions

What does the LMMP30 measure?

pH, ORP, conductivity, TDS, salinity and resistivity.

How accurate is the pH measurement?

−2.000 to 20.000 pH with ±0.002 pH accuracy and up to 5-point calibration.

What is the difference between LMMP30 and LMMP32?

LMMP32 adds ion measurement and dissolved oxygen (DO electrode supplied); LMMP30 does not.

How much data can it store?

500 data sets with date and time, with a built-in real-time clock for GLP.

Can it handle seawater samples?

Yes, in salinity mode you can choose practical salinity (PSU) or the sea water standard (ppt).

Does it have automatic temperature compensation?

Yes, automatic or manual temperature compensation over 0–100°C, with linear or pure water modes for conductivity.

What is supplied with it?

Main instrument, pH electrode, pH buffer (4.01, 7.00, 10.01 pH), conductivity cell 1K, calibration solution, electrode stand, ATC probe, USB adaptor, instruction manual, test certificate.

What are the packing size and weight?
