The HI98190 is a professional portable meter designed for accurate pH and ORP (mV) measurements in both field and laboratory applications. The exclusive CAL Check™ feature automatically verifies electrode performance and buffer condition during calibration, helping prevent measurement errors caused by contaminated buffers or aging electrodes.
Its large, backlit graphical display provides simultaneous readings of pH, mV, temperature, GLP data, and electrode status. The meter is fully waterproof, easy to operate with one hand, and supplied in a rugged carrying case. Logged data can be transferred to a PC via the integrated USB connection.
