Freezer Thermometer - constant, accurate, reassuring DefrostWatch ™

After a power interruption, it's important to know if temperature-sensitive products are still in a useable condition. DefrostWatch ™ a unique type of freezer thermometer will sit unobtrusively in a freezer and indicate whether the temperature has risen above critical levels and, crucially, for how long.

Rely on it and refer back to it

DefrostWatch ™ is an irreversible freezer thermometer indicator. Once activated, the viewing window will change from white to blue - if there is no temperature breach in the freezer, the indicator does not move. When a temperature breach does occur, the freezer thermometer indicator will show how long the breach has lasted, allowing you to take appropriate action. If the temperature returns to safe levels, indicator progress stops, helping avoid unnecessary waste.
