JQAW-5 Pipe Type CO2 Transmitter

The product model:JQAW-5
The production:China
Attention index:8785
Data download:

JQAW - 5 series pipe type carbon dioxide transmitter is specially designed for ventilation pipe application, the technology is absorb gold-plated reflecting light pipe or waveguide diffusion gas chamber light. The light absorption is  in proportion to concentration of carbon dioxide. Measuring the residual light and convert it into an analog signal.


CO2 transmitter has wide application scope, including building air quality testing. Detect carbon dioxide concentrations in the building can promote the implementation of the ventilation control strategy.
