  • Specifications

The YSI TruLab line includes the 1110 (single channel), 1310 and 1310P (single channel) and 1320 and 1320P (dual channel) instruments providing easy-to-use and calibrate instruments ideal for the laboratory.

Measure pH, mV (ORP) and temperature accurately in the laboratory with the YSI pH 1110. This benchtop instrument for basic, routine measurements in the lab is an accurate and easy-to-use solution for repeatable pH or mV measurements.


  • Single channel measurement of pH or mV (ORP) and temperature
  • AutoRead function improves repeatability
  • Easy-to-read large, segmented display for pH, mV (ORP) and temperature
  • Easy calibration with adjustable calibration timer
  • Automatic or manual temperature compensation
  • 1, 2 or 3-point calibration
  • BNC connection for pH, mV; banana connection for temperature probes
  • 3-year warranty
  • Wide selection of electrodes - pH, ORP and temperature probes


The instrument's AutoRead function indicates when a stable measurement is reached improving repeatability.


An adjustable timer indicates when to perform the next calibration routine, improving measurement accuracy.
