direct-reading temperature indicator label / disposable / for logistics

ShockWatch WarmMark® Duo offers two main functions (1) Monitor length of time above 10°C and for brief excursions above 34°C (2) Alert whenever a product has been exposed past a threshold and check for spike in temperatures. This disposable temperature indicator is mainly used in shipping and storage, to check for goods in unacceptable conditions. Whenever the indicator alerts you of a spike in temperature or provide visual evidence of exposure to objectionable temperature levels, you can check for product quality. Suitable for products that have expiry dates when exposed to certain time and temperature combinations, and products with known temperature curve.
