<0°C Temperature Indicator, 100 / pack

Product Code: 82101

Temperature indicators provide accurate, irreversible, evidence of a below threshold temperature excursion. The indicator turns from clear to magenta when the temperature falls below its threshold. A visual check of the indicator alerts the recipient if the temperature has been unacceptably cold and enables simple accept / reject decisions.

Specifications:

  • Response Time: Within 60 minutes

  • Activation: None - Product arrives ready to use. No pre-activation required

  • Accuracy: ±1°C / ±2°F

  • Quantity: pack of 100

Interpreting the Freeze Indicator: 

Freeze exposure equal to, or beyond, the time and temperature specification is shown when the indicator dot is as dark, or darker than, the reference dot.

The freeze indicator is “live,” meaning it’s continuously monitoring temperature. Because these indicators are designed to respond quickly to exposure below their threshold, they can be activated if they encounter freezing temperatures in transit. Once activated, they cannot be reused. 

From September through May, freeze indicators will ship next day air (from our US-based manufacturer) in an insulated container with heat packs. Although we take every precaution to limit the risk of exposure to cold temps in transit, if the shipment encounters delays (carrier, customs, etc.) and the weather is below freezing, it poses a risk. Because of this, we recommend whenever possible, to order these products before the coldest winter months.
