Irreversible Temperature Indicators

SMALL SELF-ADHESIVE TEMPERATURE RECORDING DECALS TURN BLACK AT 38°C TO 260°C (100°F to 500°F)

Non-reversible temperature indicator recording labels accurately and economically sense and record surface temperatures. Each recorder contains one or more sealed temperature sensitive chemical indicators which turn permanently and irreversibly from silver to black at its calibrated temperature.

Response time is less than one second with an accuracy of ±1% or 2% depending on the temperature rating. The miniature size, weight and thickness (nominal 0.01″) of the labels allow installation in areas and on parts which are not practical for other instruments.

The General Purpose Model 110 contains six temperature sensitive increments covering a range of 50°F on a single model. Ranges from 100°F to 500°F (38°C to 260°C). Rated values are printed at the indicator window in both °F and °C. High temperature models are white in color, with gold indicators. Size: 1.75″ x 0.75″.

ColdSNAP Temperature Recorders

Our ColdSNAP self-contained recorders monitor your shipments by recording a critical low temperature of refrigerated temperature sensitive products in storage or transit. The miniature self-adhesive ColdSNAP has a ±2°C accuracy bimetallic sensing element that snaps at its critical cold temperature, permanently turning an indicating window from clear into bright red. The rugged all-mechanical plastic-housed recorder has a long storage life. This unique patented design eliminates delicate chemical sensors, fragile glass and requires no batteries.

Special customer selected temperature snapping points are available from -20°C to +15°C.
Size: 1.38″ x .69″ x .22″ thick. Length with activation tab 2.13″. Weight: .15oz.

MINIATURE COLDSNAP RECORDS A CRITICAL FALLING TEMPERATURE FROM -20°C TO +15°C WITH ±2°C ACCURACY

The unique ColdSNAP+ (Plus) combines the ability to accurately record both a critical descending cold temperature and a critical ascending hot temperature in a single miniature plastic housing.

Because of its high performance, small size and light weight, the ColdSNAP+ can simply become an integral part of a packaging system to assure the quality and safety of critical temperature sensitive goods in transit or storage. The ColdSNAP+ combines the proven ±2°C accuracy of ColdSNAP to record a descending standard temperature with Irreversible Temperature Label Technology to record high temperature extremes.
