The pyrometers IS 50-LO plus and IGA 50-LO plus are digital pyrometers with fibre optics for non-contact temperature measurements on metals, ceramics, graphite etc. between 250 and 2500°C.

The optical fibre as well as the exchangeable optical head are unaffected by electromagnetic interferences (e.g. induction) and can be used in high ambient temperatures up to 250°C. Two different types of optical heads for different measuring distances and very small spot sizes (min. 0.45 mm) are available. A laser targeting light enables the exact alignment onto the measuring object.
Due to their short response time of less than 1 ms these pyrometers ideally suit for the measurement of fast heating processes.

The pyrometers are equipped with a display which shows the current temperature, when in measuring mode. Moreover it displays all instrument parameters, if they are changed via the integrated keys at the instrument. Via serial interface and the provided software InfraWin the temperature can also be displayed and stored on a PC; parametrizing can also be done.

The IS 50/67-LO plus is a special version with an extremely short wavelength for the measurement of molten metals with a very high emissivity.
