Couldn't load pickup availability
The HM Digital PSC-64D is a compact, dual-line EC/TDS monitor designed for high-output commercial and industrial water systems. Its extended measurement range makes it ideal for applications that require precise monitoring of total dissolved solids (TDS) and electrical conductivity (EC) in demanding environments.
If the TDS level rises above a user-set threshold, an audible alarm will sound, and the monitor will activate or deactivate external equipment—such as pumps, solenoid valves, or control relays—through its dry contact relay system. This built-in control feature helps maintain water quality automatically and efficiently.
Features:
- Compact “Mini” dual-line monitor
- Continuously monitors two lines simultaneously 4–20 mA output
- Extended range for EC and TDS measurement
- Audible alarm when TDS exceeds user-set level
- Dry contact relay to control pump, valve, or other device
- Includes power cord and installation accessories
- Ideal for high-output commercial systems
