The HI-83141-1 is a rugged, portable analog pH/mV/°C meter engineered for field and laboratory use. It provides fast, accurate pH, millivolt (mV) and temperature readings with a clear analog display and separate connectors for the HI-1230B pH electrode and a temperature probe for Automatic Temperature Compensation (ATC).
Manual two-point pH calibration (offset & slope trimmers) and a high input impedance ensure reliable results with a wide variety of samples. Built for convenience, the meter runs from a single 9V battery, comes with probe(s) and calibration sachets, and is housed in a compact, water-resistant case for on-site testing.
