江森CO-T1 CO傳感器
Most building codes require a very high ventilation rate in enclosed parking or areas involving vehicle repairs and operation. This must be provided during all hours of use. Most codes allow fans to be operated intermittently as long as carbon monoxide (CO) level does not excE+Ed 25 or 50ppm (check local code). A CO sensor can reduce fan energy costs by switching off or reducing ventilation when CO level is low.
The CO-T1 is a 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 loop powered sensor delivers a linear 4~20mA output that is easily integrated into any building control, ventilation or alarm system.
FEATURES
