COLO.SCIENCE – pH METERS AND ORP INSTRUMENTS
Laboratory pH meters measure pH value, ORP, mV and temperature. They provide stable and accurate readings, which makes them suitable for laboratories, industry, water treatment plants and education. With automatic temperature compensation and GLP functions, they support reliable and traceable results.
Below you can choose between portable and benchtop pH meters. Then you can open individual instruments and select the electrode type, mV range, number of calibration points and accessories that match your application.
INSTRUMENT GROUPS
- Portable models –
compact and easy to use in the field. They offer automatic temperature compensation, multi-point calibration and stable readings. This makes them practical for quick water quality checks in different environments. - Benchtop models –
provide high accuracy, a stable signal and a large display. In addition, they support advanced calibration, a wide mV range and PC connectivity, which is ideal for quality control and research laboratories.
