HM Digital HM-100
Professional Continuous Water Quality Monitoring The HM Digital HM-100 is a high-end, multi-parameter continuous monitor designed for 24/7 tracking of essential water metrics. It is a versatile instrument ideal for a wide array of applications, including hydroponics, water purification, aquaculture, laboratory testing, and wastewater regulation. By providing real-time data, it ensures that your water quality remains within optimal ranges for successful gardening or industrial processes.
Simultaneous Multi-Parameter Display This monitor features a large, easy-to-read LCD screen that displays three critical parameters simultaneously: pH, Temperature, and either EC or TDS. This eliminates the need to cycle through menus to see your primary readings, allowing for at-a-glance monitoring of your system's health.
Integrated Alarm System To protect your environment, the HM-100 includes a user-programmable alarm function. You can set high and low thresholds for each measured parameter; if the water quality drifts outside these limits, the device will provide both a visual indicator and an audible sound to alert you immediately.
Digital Calibration and Advanced ATC The unit offers simple push-button digital calibration that can be set to any point within the meter’s measurement range. It also features Automatic Temperature Compensation (ATC) using three distinct temperature coefficients, ensuring that your pH, EC, and TDS readings remain accurate even as the solution temperature fluctuates.
Durable Design and Replaceable Probes Built for longevity, the HM-100 comes with replaceable sensors (SP-P5 for pH and SP-C2 for EC/TDS/Temp), which are connected via shielded coaxial cables to minimize interference. The main unit is wall-mountable, making it a permanent fixture in your grow room or laboratory.
