  • BACnet or Modbus digital outputs
  • Backlit display
  • Analogue output option
  • User selectable gas detection range

The IAQPoint’s dual IR sensing technology offers better drift and temperature compensation for measuring ambient CO2 levels. The addition of BACnet and Modbus digital outputs make it simple to install and integrate into the existing building automation system. Units can be ordered with a simple 4-20mA analogue output or optional display. If the application does not require temperature and relative humidity, a CO2 only version is also available. Eliminating the need for additional devices and excess wiring, the IAQPoint easily snaps into a standard electrical box for simple wall mount installation. A duct mount version is also available for those applications that need to monitor incoming air from outside the building or do not wish to place the unit in plain view. The IAQPoint’s plug-and-play nature and simplified mounting dramatically reduce the overall cost of installation. Temperature and relative humidity readings are measured at the tip of the antenna that extends from the bottom of the unit. Taking these measurements outside of the enclosure guarantees the most accurate and repeatable readings. A stylish protective cover is also available for those applications where breakage or vandalism is a concern.


*About digital output protocols (via wikipedia):

Modbus is a serial communications protocol published by Modicon in 1979 for use with its programmable logic controllers (PLCs).

BACnet is a communications protocol for building automation and control networks. It is an ASHRAE, ANSI, and ISO standard protocol.

LonWorks (local operation network) is a networking platform specifically created to address the needs of control applications. The platform is built on a protocol created by Echelon Corporation for networking devices over media such as twisted pair, powerlines, fiber optics, and RF. It is used for the automation of various functions within buildings such as lighting and HVAC
