Hanna HI98199-03 Digital pH EC DO portable meter

Hanna HI98199-03 Digital pH/EC/DO Portable Multiparameter Meter – Ultimate Field Meter for Comprehensive Water Quality Testing

The Hanna HI98199-03 Digital pH EC DO portable meter is an advanced digital multiparameter meter designed for professional field and laboratory use, capable of accurately measuring pH, conductivity (EC), total dissolved solids (TDS), salinity, resistivity, dissolved oxygen (DO), and temperature in one compact, waterproof device. With robust data logging, USB-C connectivity, GLP compliance, and compatibility with smart digital probes, it is the ideal tool for water quality monitoring in environmental, industrial, aquaculture, and regulatory applications.

This model includes features tailored to meet high-precision needs, including galvanic DO measurement, automatic temperature compensation, and seawater density (σ) calculations.
