HM-100

The HM-100 is a versatile and high-performance meter designed for precise water quality testing. It combines the ability to measure pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), salinity, and temperature, making it ideal for applications such as hydroponics, water purification, aquaculture, laboratories, wastewater regulation, pools and spas, and more.

This easy-to-use device offers reliable water purity readings and is perfect for monitoring drinking water, aquariums, hydroponic systems, and water purification setups. By providing accurate TDS readings, the HM-100 helps users ensure that the water is clean and safe for consumption or other uses. With its replaceable sensors, automatic temperature compensation (ATC), and digital calibration, the HM-100 ensures precise and consistent results.

Features:
