HI99301 Portable EC/TDS and Temperature Meter for laboratory, water treatment, and field environments.
Hanna HI99301 Portable High Range EC/TDS and Temperature Meter is a high-performance, multiparameter instrument designed for accurate measurement of electrical conductivity (EC), total dissolved solids (TDS), and temperature in demanding laboratory, industrial, and water treatment applications. With a measurement range of 0.00 to 20.00 mS/cm for EC and 0.00 to 10.00 ppt for TDS, this meter is ideal for analyzing high-salinity samples, wastewater, and process water systems.
The instrument is equipped with the HI763063 EC/TDS probe, featuring a built-in temperature sensor, quick-connect DIN connector, and a 1 meter cable for flexible use in both field and laboratory environments. Automatic temperature compensation across a range of 0 to 60°C ensures consistent and accurate readings, even under fluctuating conditions.
Designed for adaptability, the HI99301 allows users to select the EC to TDS conversion factor (0.45 to 1.00) and temperature correction coefficient (0.0 to 2.4%/°C), enabling precise customization based on specific sample characteristics. This makes it highly suitable for varied applications including reverse osmosis systems, wastewater treatment, and industrial process monitoring.
The large, easy-to-read display simultaneously shows EC, TDS, and temperature readings, improving efficiency and reducing the need for multiple instruments. Users can also configure the automatic shut-off feature (8 minutes, 60 minutes, or disabled) to optimize battery usage based on operational needs.
Built for durability, the HI99301 features a rugged IP67-rated waterproof enclosure, ensuring reliable performance in harsh environments with full immersion capability and operation in temperatures from 0 to 50°C and up to 100% relative humidity.
Powered by three 1.5V AAA batteries, the meter provides up to 500 hours of continuous operation, making it ideal for extended fieldwork and continuous monitoring applications. The unit is supplied complete with the HI763063 probe, batteries, and a protective carrying case for safe transport and storage.
Widely used in wastewater treatment plants, industrial process control, HVAC systems, laboratory testing, and water quality monitoring, the HI99301 ensures accurate and dependable EC and TDS measurement for high-conductivity environments.
