Carbon Dioxide Transmitter

Carbon Dioxide Transmitter is a category of sensors that includes sensors with an electrical transmission outcome for distant carbon dioxide level monitoring There are items that include optional relays and ome of these products have their application in ventilation. Carbon Dioxide Transmitters precisely monitor CO2 content and temperature in interior spaces to aid in energy savings. A single beam dual wavelength non-dispersive infrared sensor is utilised to automatically adjust the measurements in both occupied and unoccupied buildings against light source ageing effects for better sensor accuracy. The best degree of precision is provided by the single beam dual wavelength sensor technology.
