Accucold’s AlarmKit is a NIST calibrated temperature alarm that can be installed aftermarket on any refrigerator or freezer. The alarm also functions as a thermometer, providing a NIST calibrated readout of the minimum, maximum, and current temperatures to the nearest tenth of a degree (viewable in Celsius or Fahrenheit). The temperature display is accurate within +/-.5 C when operating in -10 to 10 C ranges (and 1 C when operated outside that range). The alarm’s temperature sensor is enclosed inside a glycol-filled bottle, as recommended by the CDC to ensure the temperature readout better reflects the temperature of stored contents. This alarm is powered by a replaceable AAA lithium battery. The display screen includes a low battery alert for added convenience. The AlarmKit is calibrated in our ISO/IEC 17025:2017 accredited laboratory and ships with a certificate of calibration for your facility’s records. This alarm can be recalibrated in our laboratory.
