IMPAC Pyrometer
IPE 140/39
Special version of IPE 140 with a spectral range of 3.9 µm for non-contact temperature measurement through flames and combustion gas as well as penetrating measurement into glass. Temperature ranges between 20 to 1800 °C.
Key Features
- 3 temperature ranges between 20 to 1800 °C
- Measurement through flames and combustion gas without influencing the measurement
- Penetrating measurement into glass
- Reduction of emissivity errors
Details
The IPE 140/39 is a special pyrometer for non-contact temperature measurement of metal parts in flame heated furnaces. Like the basic IPE 140, the IPE 140/39 is a highly accurate digital pyrometer.
The narrow spectral range of 3.9 µm avoids the influence of humidity and CO2 and enables a correct measurement through flames and combustion gases. Also humidity and CO2 do not have any influence on measurements with long measuring distances.
Another application is the measurement of glass if a small penetration into the glass is necessary (e.g. glass drop). Measurement errors caused by partially cooled down surfaces can be avoided.
For optimal match of the instrument to the application 3 different focusable optics with extremely small spot sizes are available.
