HM Digital PSC-154 TDS/EC Controller with 4-20mA Output, 0-9999 µS Measurement Range, 0.1 µS/ppm Resolution, +/-2% Readout Accuracy
Hm Digital Psc-154 Tds/Ec Controller 4-20ma Output Ppm Conductivity Monitor is a 4-20mA TDS/EC controller designed to maintain optimal TDS/EC levels in commercial high-performance systems. It features an extended measuring range, digital calibration, an on-screen temperature display, a tri-color display, and a 4-20mA output. Built-in sensor for automatic temperature compensation (ATC) guarantees accurate measurements at different temperatures. A bright 5/8" L.E.D. display makes it easy to see the reading measurements. FEATURES: - Large and bright LED display. - 4-20mA output signal can be connected to PLC to record values. - An alarm will sound if the TDS/EC level exceeds the user set level. - A given point controls the device switch. - The screen display shows the temperature (C/F). - The kit includes one sensor probe (part #SP-1-PSC). PRODUCT DESCRIPTION: - EC range: 0-9999 µS - TDS range: 0 – 5000 ppm - Temperature range: 1-75°C; 33-167°F - Accuracy: ±2% (of reading) - Conversion factor: NaCl (average value 0.5) - Resolution: 0.1 µS/ppm (0-999); 1 µS/ppm (1000-9999) - ATC: Yes (1 – 65°C) - Calibration: Digital via push button - Setting the control point: One point controlled by the up/down buttons on the screen (any point in the range) - Relay control: The unit will open or close the contact when the preset ppm/µS level is reached or exceeded (simple switching). It can be used to control a pump, solenoid valve, or other device. - Relay voltage: 5V - Output signal: 4-20mA - Output Accuracy (mA): ±1% - Alarm: Constant beep (user configurable) - Display: Bright 5/8" LED display. - Probe: 1/2" threaded hole (NPT), 3 meters (9.8 feet) shielded cable - Power supply: AC 110V / AC 220V - Dimensions: 7.2 x 7.2 x 11.1 cm (2.8 x 2.8 x 4.4 inches) - Monitor weight: 241 g (8.5 oz) - Total weight (delivered): 610 g (1 lb 5.5 oz) Hm Digital Psc-154 Tds/Ec Controller is a reliable controller that will help you monitor and maintain optimal TDS/EC levels in your commercial system. Thanks to its features, you can quickly check measurements and adjust the control level using a switch and set point.
