Features:
- Range: 700 to 3500 °C
- Large field of view to easily spot the target
- Sharp, high definition image of targeted object
- Excellent optical resolution (target of 1 mm diameter can be detected at a distance of 5 m)
- Spot size as small as 0.1 mm
- High accuracy due to the specific measurement technique and spectral response
- Measurement is virtually unaffected by emissivity of target object

Intensity comparison pyrometer
Mikro PV 11
Modern intensity comparison pyrometer (successor of the disappearing filament pyrometer) for precise contol of temperatures ranging between 700 °C and 3500 °C. Target spots as small as 0.1 mm can be achieved. Mikro PV 11 is used in many fields of research and industrial manufacturing, at universities, institutes and laboratories. Measurement applications include tungsten filaments, tiny metal and ceramic samples and atomic absorption spectroscopy.
