Tempilabel and Thermax are the ideal solution to monitor and verify temperature specific operations such as climate conditions during storage and transit. They feature adhesive backing allowing them to be affixed to any surface quickly and easily. When desired temperature is reached the dot in the middle changes to black and remains that way indicating that the desired temperature has been reached. Accurate to +/- 2% of the Fahrenheit rating, Tempilabel and Thermax brands are both available in either the multiple temperature range configuration or single temperature design.
