Introduction
2.1
Appropriate use
IS 12-TSP and IGA 12-TSP are extremely precise and longer-term stable transfer standard
pyrometers which can be used for the checking of calibration sources in the respective
pyrometer spectral range.
2.2
Scope of delivery
Instrument with selectable optics, PC measurement and evaluation software „InfraWin“, works
certificate with 3 selected measuring points, user manual.
Note:
The connection cable is not included with the instrument and has to be
ordered separately (see
