The YSI TruLab pH 1110 is a single channel benchtop meter that measures pH, mV (ORP) and temperature. Its accuracy and the ease with which it can be calibrated makes it ideal for use in laboratory settings.

The TruLab pH 1110 has a wide measurement range and includes both manual and automatic temperature compensation as well as an AutoRead function that indicates when a stable measurement is reached, improving repeatability. Results are shown on a large, easy-to-read segmented display.

The TruLab pH 1110 also has an adjustable timer that indicates when to perform the next calibration routine, improving measurement accuracy.
