Details

IS 12-TSP and IGA 12-TSP are extremely precise and long-term stable transfer standard pyrometers which can be used for the checking of calibration sources. Calibration sources are subject to heavy wear due to the extremely high temperatures which they have to produce. This can lead to the fact that, over time, the temperature display at the controller no longer corresponds to the radiation temperature in the spectral range being investigated. If high precision measurements are required on the calibration source over long periods of time, we recommend that regular checks are carried out.

The IS 12-TSP or IGA 12-TSP transfer standard pyrometers have been specially designed for this purpose. They are available in several temperature ranges between 200 and 2520°C and in various spectral ranges, which means that they can be used with calibration sources with which pyrometers with Silicon or Indium Gallium Arsenide detectors can be checked.

The detectors in the TS pyrometer are thermostatically controlled to achieve this high precision. This means that the measurement is, to a large extend, independent of surrounding temperature variations and allows a resolution of 0.01 °C to be achieved.

Use of a TS pyrometer ensures that temperature values as stipulated by national institutes can be transferred to your own calibration sources to guarantee traceability to the ITS90 international temperature scale. 
In order to guarantee an adherence to high technical specifications, the TS pyrometer should be checked regularly by IMPAC. This is, however, only necessary every 2 years thanks to the pyrometer's solid construction.
