Temperature Indicators
Pages 16

Temperature indicators serve for approximate determination of bodies’ temperatures and are used tocontrol avariety of temperature treatment processes. œe temperatures are determined based on knowledge of characteristic rated temperatures, which are mean critical temperatures of the indicator. However, it should be stressed that the accuracy of these measurements is satisfactory only if the measurement conditions are similar to the standard conditions for which the temperature indicators were calibrated. Otherwise, the critical temperatures of the indicators can be di¥erent from their rated temperatures listed in the standards, and the measurements can have considerable errors.
