AVAIN LABS® HM Digital 4-in-1 Combo PH-TDS-EC-Temp COM-360

AVAIN LABS® HM Digital 4-in-1 Combo PH-TDS-EC-Temp COM-360

The AvainLabs® HM Digital 4-in-1 Combo pH-TDS-EC-Temperature Meter COM-360 is a versatile digital water quality testing instrument designed to measure pH, TDS (Total Dissolved Solids), EC (Electrical Conductivity), and Temperature in a single compact device. It is ideal for professional and routine water testing applications in laboratories, hydroponics, aquariums, water treatment, agriculture, swimming pools, and general water quality monitoring.

The COM-360 provides a pH measuring range of 0.0 to 14.0 pH, EC measurement up to 9990 µS / 9.99 mS, and TDS measurement up to 8560 ppm (mg/L). It also supports 0.5 (NaCl) and 0.7 (442) TDS scales, allowing flexible measurement for different testing requirements.

The meter features digital 1-point calibration, a water-resistant splash-proof housing, compact dimensions, and battery-powered operation, making it convenient for both laboratory and portable on-site testing.
