THERMO SCIENTIC Lab Star PH111

The Thermo Scientific Lab Star PH111 Benchtop pH Meter is a compact laboratory pH meter designed for accurate measurement of pH, ORP (mV), and temperature. Ideal for life science, biotechnology, pharmaceutical, environmental, water testing, and general laboratory applications, this digital pH meter provides precise measurements with an easy-to-read interface.

The Thermo Scientific PH111 offers a wide pH measurement range of -2.000 to 18.000 pH, selectable resolution down to 0.001 pH, and support for 1- to 5-point pH calibration. A 5-inch backlit LCD displays pH, mV, and temperature simultaneously, while onboard memory stores up to 500 measurements with date and time stamps.

Its compact benchtop pH meter design and IP54-rated protection make it suitable for routine laboratory testing, solution analysis, quality control, and research workflows.
