CO Transmitter

Most building codes require a very high ventilation rate in enclosed parking or in areas involving vehicle repairs and operation. This must be provided during all hours of use. Most codes allow fans to be operated intermittently or complete shut-off as long as the carbon monoxide (CO) concentration in the space does not exceed 25 or 50ppm (check local code). A CO sensor can be used to reduce fan energy costs by switching off or reducing fan speed when CO level is low.
The CO-T1 is a simple CO sensor/transmitter designed specifically for these applications. It delivers all the advantages of electrochemical sensing in a durable, long life (5-year) package and at attractive low price. The 2-wire loop powered sensor delivers a linear 4~20mA output that is easily integrated into any building control, ventilation or alarm system.
