The DMS-12 alarm system can be used for temperature monitoring of a cold chain in the food industry. T-12 alarms are fitted at the various points at which the temperature is to be monitored. The base displays all of the alarms and the current temperature measurements clearly and enables convenient export of temperature records by USB interface. Threshold values at which a temperature alarm is triggered can also be set. An overview can always be maintained and discrepancies in temperature are displayed immediately. There are portable receivers to notify employees when they are elsewhere in he building and they draw attention to a temperature alarm by vibration and an audio signal. The display also shows the location at which the alarm was triggered.
