CO2 and Temperature Transmitter for Duct Mounting

HLX850

The HLX850 is optimized for use in building management applications. A multi-point CO2 and temperature factory adjustment procedure leads to an excellent CO2 measurement accuracy over the entire temperature working range.
The dual wavelength NDIR CO2 sensor compensates for aging effects, is highly insensitive to pollution and offers outstanding long term stability.
The HLX850 can be optionally fitted with a passive temperature sensor output. An optional kit facilitates easy configuration and adjustment.
