H5421 CO2 meter with movable sensor and two output relays and RS485 COMET output

Description

H5421 CO2 meter with movable sensor and two output relays and RS485 output.

The H5421 is equipped with a CO2 probe with a 1 metre cable. Optional 2 or 4 metre cables are also available.

Indoor carbon dioxide levels are often an important parameter and indicator of air quality. Especially in buildings where several people are present at the same time, such as schools, conference rooms, cinema halls, theatres and hospitals. A carbon dioxide sensor can help improve indoor air quality.

A visual display of the CO2 concentration in the air:

• green: CO2 concentration 0 … 1000 ppm
• bright yellow: CO2 concentration 1001 … 1200 ppm
• illuminated red: CO2 concentration 1201 ppm or more
