RK300-03 CO2 sensor (indoor or outdoor models)
The RK300-03 CO2 transmitter uses the NDIR principle to detect the concentration of CO2 in the air.
Designed with advanced infrared absorption gas detection technology, it has a precise optical path and an excellent circuit design.
Model RK300-03A for Indoor use.
Model RK300-03B for Outdoor use.
One temperature sensor built-in realizes temperature compensation to ensure the accuracy of measurement.
It is without oxygen dependence, of long service life.
2 Models: for indoor and outdoor use:
Model RK300-03A for Indoor use.
Model RK300-03B for Outdoor use.
