Product catalog summary

Introduction
The Mikro Type PV 11 is an intensity comparison pyrometer designed for precise temperature measurement ranging from +700 °C to +3500 °C. It is suitable for objects as small as 0.1 mm in diameter and has been in use since 1976.

Measurement Principle
The PV 11 operates on the principle of visual intensity comparison, using a calibrated reference lamp. The user adjusts the lamp's intensity to match the brightness of the measuring object, allowing the temperature to be read from a digital display. This method is highly accurate and stable over time, requiring no recalibration.

Features

High optical resolution of 5000:1, enabling measurement of small objects from a distance.
Focusable lens for distances from 1 m to infinity, with optional lenses for closer ranges.
Six filter stages and a multi-turn potentiometer for precise intensity adjustment.
Stable readings due to continuous monitoring of the light source's brightness.

Applications

Laboratory instruments for temperature determination in graphite cells.
Vacuum furnaces for metal sample temperature measurement.
Nuclear research for sintering uranium tablets.
Incandescent bulb manufacturing for filament temperature limits.
Glass fiber production for reliable distance measurement.
Used as a reference pyrometer in universities.

Technical Specifications

Measuring range: +700 to +3500 °C, divided into six ranges.
Display resolution: 1 K.
Accuracy varies with temperature range, from 0.6% to 2.0% of reading.
Repeatability: 3 K.
Minimum target diameter: 0.3 mm at 1 m, 0.1 mm at 0.2 m with lens.
RS 232 interface for PC connection, with included software.
Power supply: 15 V DC or 230 V AC.
Dimensions: 100 x 100 x 450 mm.

Accessories

Close lens set for various distances.
Grey filters for extending the measuring range.
Protective glass and floor stand.

Conclusion
The Mikro PV 11 pyrometer is a robust and precise instrument for non-contact temperature measurement, offering high accuracy and stability across a wide range of applications.
