PS-100

The HM Digital PS-100 is a reliable panel-mount Total Dissolved Solids (TDS) controller designed to monitor and manage TDS levels in water. Equipped with advanced features like alarm settings, digital calibration, and a tri-color display, this device ensures precision and ease of use. Its built-in sensor for Automatic Temperature Compensation (ATC) guarantees accurate readings across a range of temperatures. The bright 5/8″ LED display offers clear visibility for real-time monitoring.

Key Features:

1. Maximum Set Point Control:
   Helps maintain TDS levels within a defined limit.
   Activates a warning light, optional alarm, and switches the dry contact position if TDS levels exceed the set point.
   Automatically resets once TDS levels drop below the set point.

2. Relay Control:
   Sends an analog signal to operate external devices like pumps or valves when TDS levels reach the set threshold.

3. User-Friendly Design:
   Adjustable calibration.
   On-screen up/down buttons for easy setting adjustments.

4. Optional Alarm:
   Steady beep alert, configurable by the user.

5. Automatic Temperature Compensation (ATC):
   Ensures accurate readings between 1°C to 65°C.

6. Durable Build:
   Includes a probe with a 1/2-inch bushing and a 3-meter (9.8 ft) shielded cable.
   Compact and lightweight for easy installation.
