ABOUT THE LONG TERM STABILITY AND ACCURACY
CO2 and Temperature concentrations for AirTest TR9000 Products using
Dioxide Transmitter With Temperature.
wall mount case with display for CO2, temperature relative humidity
TR9230 family of products senses CO2 and temperature but also has the
capability to control a VAV box based on temperature
and ventilation. It is designed as a cost effective platform for new
or retrofit VAV applications that requires minimal
changes to existing control systems.
TR9240 integrates a setback thermostat, CO2 control and economizer control
into a single wall mounted device. It is ideal for
single zone applications where the need for ventilation may vary including
school classrooms, meeting rooms and retail spaces. Versions are available
with two stages of cooling or one state each of heating
and cooling. It is designed as a cost effective platform for
new or retrofit thermostat applications

Calibrating CO2 Transmitter.
9300 series CO2 monitor is designed to provide warning of elevated CO2
levels that may be
EE80 series combines CO2, relative humidity (RH) and temperature (T)
measurement in one housing. The snap-in mounting concept
stands for easy installation and replacement within seconds.
TR9000 products are can be provided with an advanced LonWorks® interface
that allows multiple sensors to communicate on a twisted
pair network. This feature is available as an option, or can be retrofitted
onto any AirTest TR9000 product. This feature will allow interrogation
of the sensor for temperature, CO2 and an optional
binary input on the sensor (e.g. Occupancy sensor) over a LonWorks®
network. For products with control capability such as the TR9230 and
TR9240 communication using the multi task LonWorks®
protocol 8500 Comfort Controller, allows remote adjustment
and control of a variety of devices.
