The Polwax CD50 is an advanced carbon dioxide (CO₂) transmitter designed to deliver accurate and reliable CO₂ concentration measurements across diverse environments. Engineered with precision and durability in mind, the CD50 ensures consistent performance for both indoor and industrial applications.
The gas-permeable membrane on the sensor shell has good gas permeability, the gas in the environment can circulate freely, and the imported sensor is built in the shell, which has high measurement accuracy. Quick Response. Our company provides a one-year warranty for the product. Under normal circumstances, the service life is up to 5 years. Our co2 sensor housing is waterproof and dustproof and is not easily damaged. Only need to replace the breathable membrane regularly every year.
