Monitoring of temperature excursions between two present limits is provided by the Temperature Monitor. If limits are exceeded, power to the monitored unit is removed, a warning lamp is illuminated and an audible alarm is activated. When temperature is again within limits, the monitor may be reset for continued operation. A combination pyrometer scale provides reading at a glance with both Fahrenheit and Centigrade ranges.
