How do you know that your clinical thermometer is correct?
In this article we present an updated product solution for the calibration of clinical thermometers and thermal imagers. The model is called the BlackBody 989 and is produced by our business partner, Isotech in the UK.
There has been great demand and the previous model, the 988, has been widely used during the current pandemic. Now Isotech has listened to its customers and made a new model that is smaller, easier to place, and has a wider temperature range and computer interface.
The unit is what is known as a black body and has a temperature range from 20 to 50 °C, with a resolution of 0.1 °C. The unit is 70 mm in diameter and has an emission factor of 0.97, which is the same as human skin.
The black body can be complemented with a tube to improve the measurement if desired. These are available in the lengths 40 mm and 210 mm. The shorter one is designed for hand-held clinical thermometers and the longer one is for thermal imagers.
The stated accuracy is ±0.2 degrees.
With the help of this unit, it has been possible to significantly improve measurement accuracy with use all around the world. One use, for example, is for thermal imagers that have been placed out to monitor the temperature of people walking by at train stations and airports.
The unit is also highly suitable to use to check the function, accuracy and performance of hand-held thermometers.
To sum up, this is an accurate, handy and portable unit that can easily be carried and used in different places to ensure reliable temperature measurement.
