Hanna Portable Waterproof pH/EC/TDS Low Range Meter - H1991300

The Hanna Instruments HI991300 is a rugged, portable, multiparameter meter designed for accurate water quality testing in environmental, field, industrial, and laboratory settings. It combines pH, electrical conductivity (EC), total dissolved solids (TDS), and temperature measurements into a single handheld instrument—making it an ideal tool for environmental sampling, water analysis, and on-site monitoring of freshwater, aquaculture, wastewater, and process water.
