Waterproof pH tester with Large dual-level LCD that displays pH and temperature (°C or °F). The large display shows readings in an extended range from -2.0 to 16.0 pH (pH56 has a 0.01 pH resolution) and simultaneously shows temperature from -5.0 to 105.0°C or 23.0 to 221.0°F. They have a stability indicator and hold function that freezes the display for easy and accurate recording.

The large display also has graphic symbols to guide you through all operations. Complete with a temperature probe for faster and more precise temperature measurement they compensate automatically for temperature. Calibration is made automatically in 1 or 2 points with memorized standard and NIST buffer sets. Auto power OFF saves battery power after non-use.

Comes with a really nice case and sample packs of calibration solutions.
Testing pH has never been easier!

Always clean the electrode after each use with our electrode Cleaning Solution,
and store your meter with the electrode wet by adding a few drops of Storage Solution into the protective cap.
With proper care and feeding this meter should last years.
