HM Digital HM-100 Hydromaster Continuous pH/EC/TDS/Salinity/Temp Monitor
Accurately monitor and maintain optimal water quality with the HM Digital HM-100 Hydromaster. This versatile continuous monitor offers comprehensive and precise measurement of pH, electrical conductivity (EC), total dissolved solids (TDS), salinity, and temperature. Designed for a wide range of applications, the HM-100 Hydromaster is a valuable tool for hydroponics, aquariums, water treatment facilities, laboratories, and more.
Key Features:
- Comprehensive Monitoring: Continuously measures 5 essential water parameters: pH, EC, TDS, salinity, and temperature.
- Four Scales: Provides flexibility with four different measurement scales for pH, EC (mS), TDS (ppm with 0.5 NaCl or 0.7 442™ scale).
- Automatic Temperature Compensation (ATC): Ensures accurate readings across a wide temperature range (0.0 – 60.0 °C / 32.0 – 122.0 °F).
- Digital Calibration: Easily calibrate the meter to any point within its range with the push of a button.
- Data-Hold Function: Stores up to 6 data values for convenient recording and analysis.
- Large, Easy-to-Read LCD: Clearly displays 3 parameters simultaneously (pH/EC or TDS/Temp) for quick reference.
- Replaceable Sensors: Easily replace the conductivity (SP-C2) and pH (SP-P5) sensors for long-lasting use.
