Product Description

The Dwyer CO2 detector CDTA-5N000 measures indoor air quality with ±8 ppm/°C accuracy at 1100 ppm and 2 min response time for 99%. It supports RS-485 Modbus RTU or BACnet MS/TP communication on 10 to 42 VDC / 10 to 30 VAC power, fitting HVAC and building automation systems.

Frequently Asked Questions

What is the Dwyer CDTA-5N000 CO2 detector used for?

The Dwyer CDTA-5N000 measures indoor air quality by monitoring CO2, humidity, and temperature. It is used in HVAC and building automation systems to control ventilation and ensure occupant comfort. The detector supports RS-485 Modbus RTU or BACnet MS/TP communication for integration with building management systems.

What are the specifications of the Dwyer CDTA-5N000?

The Dwyer CDTA-5N000 has a CO2 accuracy of ±40 ppm ±3% of reading, with a temperature dependence of ±8 ppm/°C at 1100 ppm. It operates on 10 to 42 VDC or 10 to 30 VAC power, consuming 1.2 watts peak. The CO2 response time is 2 minutes for 99% of a step change, and it measures CO2 from 0 to 2000 or 5000 ppm, humidity from 10 to 95% RH, and temperature from 0 to +50°C.

Where to buy the Dwyer CDTA-5N000 in Singapore?

You can source the Dwyer CDTA-5N000 CO2 detector through 3G Electric in Singapore. We handle logistics, customs clearance, and delivery to your facility.
