Description
The HM Digital EC-3 Electrical Conductivity Tester is a rugged, pocket-sized handheld EC meter designed for versatile applications from hydroponic nutrient management and aquaculture to water purification and industrial wastewater treatment.
It features a 0 to 9990 µS/cm measurement range with 1 µS resolution up to 999 µS and 10 µS resolution above (indicated by a “×10” icon), built-in digital thermometer with automatic temperature compensation from 1 to 50 °C, and an accuracy of ±2 %. The EC-3 comes factory-calibrated with a 1413 µS KCl solution and can be user-recalibrated via a mini-screwdriver for precision control.
Designed for convenience, the EC-3 incorporates a hold function to freeze readings, an auto-off feature to conserve batteries after 10 minutes of inactivity, and a clear LCD display powered by two LR44 button cells for up to 1000 hours of continuous use. Housed in a durable black vinyl carrying case with belt clip, it withstands toolbox wear and keeps your meter protected on the go.
Driven by advanced microprocessor technology, this EC meter delivers stable, reliable measurements that help growers optimise nutrient dosing, monitor water quality, and maintain ideal growing conditions for healthier plants and higher yields.
