Monitors and controls dosing or injection systems.
Large, bright tri-color L.E.D. display.
Two adjustable set points keep TDS levels within a range.
An alarm will sound if the TDS reaches the maximum set point, and will start or stop a device (pump, valve, etc.) via switching a dry contact position.
Once the TDS level falls to the minimum set point, the alarm will stop and the dry contacts will switch to the normal position.
Digital calibration.
On-screen temperature display.
Installs easily in minutes.
Includes one sensor probe.
Protective cover also available (sold separately)
New controller includes extended range, digital calibration, on-screen temperature and tri-color display.
SPECIFICATIONS
TDS Range: 0 - 5000 ppm
Accuracy: ±2% (of the reading)
Resolution: 0.1 ppm (0-999); 1 ppm (1000-9999)
ATC: Yes (1 - 80 degrees Celsius)
Calibration: Adjustable (manual by push button)
Factory Calibration: 342 ppm NaCl
Set Points: Adjustable by push button. Set Point 2: Maximum TDS Limit. Set Point 1: Lower TDS Level (deactivates Set Point 2).
Relay Control: The unit will transmit an analog signal (simple switch) via open or
closed contacts to a device (e.g. pump/valve) when the ppm level reaches the maximum TDS
limit (Set Point 2). The contacts are switched back to the normal position once the TDS
level falls to the lower TDS level (Set Point 1).
