The ColdSNAP transit thermometer is a reliable and inexpensive indicator for temperature-critical shipments, says the company. It consists of a bimetallic sensing element that snaps at a predetermined temperature, turning an indicator window bright red. The thermometers are available in both descending (cooling) and ascending (warming) versions, and will detect critical temperatures from –20Â° to 40Â°C with an accuracy of ±2Â°. The unit is activated by the user and can be shipped and stored outside of special temperature-controlled environments, the company says.
