Senva CT1D-E3D : Duct CO2/Temperature Combo Sensor, 10K Type II Thermistor, Selectable Outputs: 4-20 mA, 0-5 VDC, or 0-10 VDC, LCD Display, 7-Year Limited Warranty

Self-calibrating NDIR sensor for high accuracy. An built-in LCD display makes set up a snap, and a standard solid-state setpoint relay makes demand ventilation easy. Probe is non-directional for accurate readings and ease of installation. Dual 4-20mA and 0-10/5 vdc outputs.

Features

  • Integrated display and push-button menus for field selectable scale, calibration, and operational modes
  • Dual 4-20mA and 0-5V/0-10V output (jumper selectable)
  • Integrated high-reliability solid-state set-point relay is ideal for direct control applications; easy to set up thanks to LCD
  • Non-dispersive infrared sensing element (NDIR)
  • Field replaceable CO2 sensor
  • 15+ year life expectancy on CO2 sensing element
  • Industry leading 7-year limited warranty on electronics; NDIR module 3 years
  • Selectable auto-calibration mode returns sensor to baseline values
  • ±30ppm, ±3% of reading
