Frost Protection Instruments

Help you protect your crops from Frost Damage

"Frost Alarm" has come to mean an electronic device designed to monitor temperature and give warning when temperature falls to a setpoint. Some of Westach's frostalarms give this warning in the form of a buzzer. Others have a relay closure output used to control a sprinkler valve or other frost prevention device. (Some have both a relay and a buzzer). And some are designed to flash a warning light from a remote location. There are presently thousands of these simple, proven, American made, Westach frost protection instruments installed at orchards, vineyards and farms, all over the world.
