HM Digital
The HM-500 HydroMaster by HM Digital is a premium, all-in-one continuous monitoring system engineered for precise laboratory and industrial analysis. This sophisticated device provides accurate, stable readings of four critical parameters simultaneously: pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), and temperature.
Designed for versatile deployment, the HM-500 features a user-friendly LCD touch-screen with auto-backlighting and supports both portable use via a rechargeable battery and fixed installation (wall-mounted or benchtop). Proactive monitoring is enhanced by adjustable high/low alarms, while automatic temperature compensation (ATC) ensures data integrity across varying environments.

What critical water quality parameters does the HM-500 monitor simultaneously?
The HM-500 HydroMaster provides real-time, continuous monitoring of four essential water parameters: pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), and temperature. This advanced premium monitor simultaneously displays these readings on a user-friendly LCD touch-type screen for proactive system management.
How does Automatic Temperature Compensation enhance HM-500 readings?
Accuracy in water analysis is critical. The HM-500 features a built-in sensor for Automatic Temperature Compensation (ATC). This technology automatically adjusts readings based on solution temperature, ensuring that measurements of pH, EC, and TDS remain stable and dependable even in fluctuating operating environments.
Is the HM Digital HydroMaster suitable for portable field use?
Yes, the HM Digital HydroMaster is designed for flexible mobility. While perfect for wall-mounted or benchtop installations in laboratory or water treatment settings, the unit is equipped with a rechargeable lithium-ion battery and a rugged design, making it highly suitable for environmental monitoring.
What kind of maintenance and calibration do the HydroMaster probes require?
For consistent data integrity, the HM Digital HydroMaster supports digital calibration for precise adjustments of both the ABS-body EC probe with Platinum electrodes and the Single Junction pH Sensor. Regular calibration using standard solutions ensures high-resolution accuracy for critical applications like hydroponics.
What are the specific measurement ranges for TDS and EC on the HM-500?
The HM-500 HydroMaster offers high-resolution analysis across wide ranges. Electrical Conductivity (EC) is measured from 0 to 9999 µS or 0 to 20.00 mS. Total Dissolved Solids (TDS) ranges from 0 to 9999 ppm or 0 to 10.00 ppt, ensuring comprehensive data capturing.
