Applications
GMP252 is ideal for agriculture,
refrigeration, greenhouses, and
demanding HVAC applications where
stable and accurate ppm-level CO2
measurements are needed.
A flow-through adapter with gas ports is
available as an accessory, enabling
tubing for easy and flexible remote
measurement with a separate pump. A
multiplexer can also be added for
sampling gas from several locations.
