HI-98194 provides multiparameter measurement in a compact and rugged IP67 waterproof enclosure. Ideal for demanding application, this meter features our rugged, quick connect multi-function probe with field replaceable sensors. The HI-98194 measures pH/mV, ORP, Conductivity, TDS, Resistivity, Salinity, Seawater, Dissolved Oxygen, Atmospheric Pressure and Temperature

A backlit, graphic LCD provides easy to read resolution even in low-lit areas. A combination of dedicated and soft keys allows easy, intuitive operation in a choice of languages.

HI-98194 allows users to store up to 45,000 continuous or log-on demand samples with logging intervals from one second to three hours. Logged data can be later transferred to a PC with the HI-920015 micro USB cable and Hanna software.

Comprehensive GLP data includes data from the last five calibrations. The contextual Help Menu can be accessed to obtain on-screen information and assistance about each feature at the touch of a button.

The HI-7698194 probe features a quick connect DIN connector to make attaching and removing the probe simple and easy.
