CO2 measuring transducer GT10-CO2-1R - Greisinger electronic
Co2 measuring transducer
Properties:
Due to the fact, that CO2 is
an important indicator for the quality of air in rooms, it´s super
important
to measure the CO2 content.
The recommended CO2 limit value for ambient air is 1,000 ppm.
An exceeding of this limit causes tiredness and a loss of
concentration.
The high quality and precise CO2-transducer works according
to the infrared principle (NDIR).
An auto-calibration procedure compensates aging effects and is
responsible
for an execellent long therm stability of this CO2 transducer.
Due to the freely adjustable output signal the transmitter could be used
for
nearly each existing controller input etc.
Additionally, there is a local display, which shows beside the actual CO2
concentration, the minimum and maximum values as well as an optical
alarm.
Advantages:
exellent long-term stability
auto-calibration procedure
for monitoring the recommended
CO2 concentration in ambient air
