Profile: Thermalarm Products, Inc. is a provider of thermometers with alarms. Our Protect-it Alarm System is sued to provide an inexpensive alarm system capable of detecting and alerting to the critical environmental conditions of any greenhouse, animal confinement, or farming operation. Our 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. Our Thermalarm III uses hermetically sealed magnetic switches to trigger an alarm condition, eliminating concerns with corrosion and particle contamination of the contacts.
