Measure −2 to +18 pH, −2000 to +2000 mV and −5 to +105 °C or 23 to 221 °F to ensure comprehensive measurement capabilities. Perform one to five point pH calibrations, one point ORP calibrations and one point temperature adjustment calibrations for proficient SOP compliance. View active pH, ORP and temperature calibration logs with date and time stamp to ensure accurate, reproducible measurements.

It is the pH meter and stand option, which allows you to purchase your pH electrode separately. The standard pH meter kit option, for common pH samples such as drinking water, tap water, buffers (non-TRIS) and general purpose student use.

It is the easy-to-clean bio pH meter kit option, for pH samples containing TRIS buffers, proteins, sulfides, halides or other components that can interfere with silver-chloride; included refillable pH electrode is easy-to-clean and restore. The low-maintenance bio pH meter kit option, for pH samples containing TRIS buffers, proteins, sulfides, halides or other components that can interfere with silver-chloride; included gel-filled pH electrode is low-maintenance and easy to operate. It is the difficult sample pH meter kit option, for pH samples that are thick, viscous or semi-solid including foods, beverages, wastewaters, emulsions, soils, slurries, suspended solids or sludges.
