ABSTRACT:
An alarm for a milk cooler which sounds when the temperature of milk within the cooler exceeds a predetermined value. A switch permits the device to be turned off to prevent it from sounding when milk is being discharged from the cooler or when the cooler is being cleaned with hot cleaning solvent. However when fresh milk is being introduced into the cooler that switch is overridden and the alarm sounds should the milk not be cooled to the required temperature after a predetermined interval of time.
