Alarms

Thermalarm 3 Temperature Gauge - Critical Temperature gauges available in normally open or normally closed models.

The ThermAlarm II is well-suited to applications requiring a narrow high-low temperature range, or where recurring temperature fluctuations of only a few degrees must be sensed.

A compact power outage monitoring device to detect power failures.

When the temperature exceeds your settings the sensor triggers an alarm. It requires no power for operation and multiple units may be wired in series to a single input.
