TruLab 1320 and 1320P pH/mV/ISE Benchtop Meters

Additional Views

Measure pH, mV (ORP), ISE and temperature accurately in the laboratory with the YSI pH 1320 or 1320P with built-in printer.

The TruLab pH/ISE 1320 benchtop meter is the ideal laboratory instrument for reliable measurements with automatic documentation for GLP compliance. The 1320 benchtop is an accurate, easy-to-use solution for the measurement of pH/mV/ISE in the laboratory. Available with or without a built in printer. The 1320 has internal memory. Stored data can be sent to a PC via USB or to an optional built-in printer available on the 1320P.


  • Simultaneous dual measurement of pH, mV (ORP) or ISE and temperature (2-channel benchtop meter)
  • AutoRead functionimproves repeatability
  • Easy-to-read backlit display with text menu for easy operation for pH, mV (ORP), ISE and temperature
  • Fast data transfer via USB in .csv or ASCII format or the optional integrated printer
  • Easy calibration with adjustable calibration timer
  • Automatic or manual temperature compensation
  • 1, 2, 3, 4 or 5 point calibration for pH
  • 1, 2, 3, 4, 5, 6 or 7 point calibration for ISE, also non- linear
  • BNC connection for pH, mV and ISEs; banana connection for temperature probes
  • Continuous Monitoring Control (CMC) function for monitoring the ideal measuring range for pH measurements based on the last calibration
  • 3-year manufacturer's warranty
  • GLP/AQA compliant
  • Wide selection of electrodes - pH, ORP, ISE and temperature probes
