AVTECH’s Extreme Temperature Sensor monitors a wide range of 
cold temperatures with a rugged thermocouple and 
smart ID box that communicates readings 
to your Room Alert analog sensor 
(built-in or external). This reliable 
sensor has a range of -328º F to 
32º F (-200º C to 0º C), making                                                                                                                                  
it perfect for your low temperature 
threshold monitoring.
