Electron Microscopy Sciences Scienceware FreezGuard™ Alarm Fahrenheit

Supplier: Electron Microscopy Sciences 7209220

The FreeGuard Alarm monitors freezers and coolers and detects any variance of +/-1 degree C in temperatures between -20 degree C and 13 degree C (-5 degree F to 55 degree F). If the temperature falls out of the range set by the user, the resonant alarm will sound for up to three days. Should the temperature correct itself, an LED will indicate that a variance has occurred. The alarm can be reset manually. A beep will signal when the 9V battery (not included) is low. For added protection, and extra life, a second battery can be connected.
The unit mounts with self-adhesive tape or screw. Unit comes with a 3 meter probe lead. The weight without the battery is 144 g (5.1 oz).
