KoolWatch Programmable Electronic Temperature Indicators

Temperature Indicators

KoolWatch™

  • Wide-range
  • Single-use
  • Programmable Electronic

Accurately monitors two high and two low threshold response temperatures (from -20°C to +60°C), and the duration of high and low temperature excursions. For refrigerated applications, the KoolWatch is accurate within ±0.5°C.

TMC Thermax®

  • Ascending High Temperature
  • Single-use
  • Chemically Activated

Uses an irreversible dye change to indicate when the monitored environment reaches its specified ascending high threshold temperature.

WarmMark™ and 3M MonitorMark™

  • Ascending Temperature
  • Single-use
  • Chemically Activated

Uses an irreversible dye change to indicate when the monitored environment has reached its specified ascending threshold temperature.

ColdMark™ and 3M Freeze Watch™

  • Descending Low Temperature
  • Single-use
  • Chemically Activated

Uses an irreversible dye change to indicate when the monitored environment has reached a specified descending low/cold threshold temperature.

Temperature Loggers

Monitor In-Transit Temperature Chart Recorder

  • Wide-range
  • Single-use
  • Battery Powered

A tamper-resistant, simple-to-operate, highly reliable battery-powered device that measures temperatures during a 10-day run time. It generates a permanent paper strip chart data record of temperature conditions and time duration.

Onset HOBO® Pendant Data Loggers

  • Wide-range
  • Multiple-use
  • Electronic Temperature

Provides a wide range of temperature readings (20°C to +70°C) for both short- term shipping applications and year-long remote deployments. Miniature in size, water-resistant, value-priced, and has an 8K memory capacity.
