Description
The HI99300 is a versatile portable meter engineered for low range conductivity and TDS monitoring in applications such as reverse osmosis systems, HVAC maintenance, and wastewater treatment. It offers EC accuracy of ± 2% FSand TDS accuracy of ± 2% FS, with automatic one-point calibration at 1413 µS/cm (EC) or 1382 ppm / 1500 ppm (TDS) depending on the selected conversion factor. Users can easily switch between EC and TDS modes with a dedicated button, while the adjustable TDS conversion factor (0.45 to 1.00) allows customization based on solution characteristics.
Equipped with the HI763063 two-pole probe, the meter features a clog-resistant design that is easy to clean and includes a built-in temperature sensor for automatic temperature compensation from 0 to 60°C, with an adjustable temperature coefficient (0.0 to 2.4%/°C). The large multi-level LCD displays measurement, temperature, and calibration guidance simultaneously, while icons indicate stability and battery status. With Battery Error Prevention System (BEPS), instability indicator, 500-hour battery life (AAA x3), and a rugged thermoformed carrying case, the HI99300 is built for dependable field performance.
