Refrigeration

Temperature monitoring for walk-ins, reach-ins, coolers and refrigerated cases — panel and door-mount thermometers, min/max units with high and low alarms, cooler thermometers, and data loggers for recorded temperature history. Most are built for continuous use in wet, cold conditions.

Sensing types here include thermocouple, thermistor, vapor tension, bi-metal and RTD. Vapor tension and bi-metal dials are the usual choice for a door or wall mount that needs no power; digital and logger-based units are the choice when you need alarms or a recorded history.
