DUT series is a CO2 and Temperature transmitter with relay, which sensor modules are installed inside the probe, detecting CO2 ppm concentration value inside ducts and send signal to remote host through analog voltage/current or RS485-Modbus standard protocol.

∙ Application: Automatic indoor ventilation system, Agricultural, livestock industry

∙ CO2 Measurement Range :

  0 ~ 2,000/3,000/5,000/10,000ppm - Optional (2%/3%/5% Optional)

∙ Accuracy : 3% ±50ppm of reading (DUT-1000), 3% ±30ppm(DUT-2000)

∙ Input Power : 24VAC/DC, ±20%, 50/60Hz, 3wired/4wired (Optional)

∙ Output : RS485 Mod-bus, 2 ~ 10V DC/4 ~ 20mA, Relay: 1A, 120VAC, or 24VDC
