SD023
SD-023 is a low-cost CO2 transmitter for installation in the climate
zone or in the ventilation duct. The SD-023 measures CO2 concentration
in the ambient air up to 2000 ppm and transforms the data into an
analogue 0/2..10 Volt output signal.
The patented goldplated measuring element is based on infrared
(NDIR) waveguide technology. This principle garantuees reliable
measurement. By controlling the ventilation based on the measured
values, it helps you decreasing your energy consumption while creating
a healthier indoor climate. |
