HM Digital - HydroMaster HM-200 Portable pH/TDS/EC/Temp Meter

Brand: HM Digital

HM Digital HydroMaster HM-200 Portable pH/TDS/EC/Temp Meter

The HM Digital HydroMaster HM-200 is a portable monitor that measures pH, electrical conductivity (EC), total dissolved solids (TDS) and temperature through two dedicated probes. Its backlit LCD shows pH, temperature and EC/TDS at the same time, and it can be calibrated with a range of calibration solutions and buffers.

With 2 m (80 in) probe cables and AA battery power, the HM-200 travels between reservoirs, batch tanks and irrigation zones in indoor cultivation and controlled-environment agriculture facilities. Operators can save up to 20 readings during a walk-through and recall them later, and both the pH probe (SP-P5) and the EC/TDS/temp sensor (SP-C2) are replaceable.

Available Options

• HM-200 meter - ships with SP-C2 EC/TDS/temp sensor, SP-P5 pH probe, protective sleeve, pH 4 and pH 7 buffer packets and 2 AA batteries

• Temperature range 32 - 130 deg F (0 - 55 deg C), +/- 1 deg accuracy
• Scales: pH, uS, mS, ppm 0.5 (NaCl) and ppm 0.7 (442)
• Automatic temperature compensation from 0.0 - 60.0 deg C
• Push-button digital calibration; factory calibrated for pH and EC/TDS
• Stores up to 20 readings; auto shut-off after 5 minutes
• Single-junction Ag/AgCl pH probe and conductivity sensor on 2 m (80 in) cables
• Runs on 2 AA batteries; approx. 5.5 x 2.6 x 1.1 in (14 x 6.6 x 2.8 cm)
• One-year limited warranty on the meter and EC probe; six months on the pH probe

Ideal Applications

• Walk-through pH and EC/TDS checks of reservoirs and batch tanks
• Irrigation and runoff spot testing across multiple zones
• Verifying in-line controller and doser readings
• Portable water-quality testing for RO and source water
