Every device used for process-critical measurements should be checked occasionally to (check for truth/prove true) it continues to deliver the needed/demanded (quality of being very close to the truth or true number). Where (change to make better/related to changing something) is possible, a device measuring outside of expected limits should be brought back to an acceptable performance level, but in the case of non-(able to be changed or moved the way you want) equipment the moving away or measurement performance should be recorded and a decision made on whether it remains fit for purpose.In the case of temperature measurement equipment, the properties of bimetals and thermocouple wire change with use and time (especially when used at high/higher temperatures) resulting in measurement drift. Also, a thermocouple probe may be damaged in service, possibly mechanically or by (slow chemical breakdown of something/rust, etc.), resulting in fast (worsening / rusting, crumbling, etc.) of the wire. RTD's and (devices that change resistance as temperature changes) are also both delicate and breakable devices and easily damaged, so should be checked occasionally. The same applies for IR thermometers and thermal imaging cameras. Quality standards generally leave it to the user to decide how often a device should be adjusted (for accuracy). However, a person (who carefully checks business records) will expect a sound reason for whatever frequency is given. When beginning and building on an (adjustment accuracy-related) frequency (serious thought/something to think about/respect) should be given to type of use the device sees, the risk of damage and the rate of drift (which can be decided/figured out from historical (an adjustment for accuracy) records).The simplest way to adjust (for accuracy) a temperature sensor is to check how it reads the temperature of two physical constants: the temperature at which ice melts and the boiling point of water (although the last thing just mentioned should be corrected for (related to the air outside) pressure). While quick and inexpensive, one weakness of this method is that it is usually not a NIST traceable (an adjustment for accuracy).UIC provides a complete (adjustment accuracy-related) service for all of your thermometry needs.
