In 1989 Wintronics was contracted to calibrate and repair  HEITRONICS' Infrared Thermometers (also called Infrared Radiation Thermometers, Pyrometers or Radiometers). Wintronics became the exclusive USA Sales and Service Center in 1995.


HEITRONICS Infrarot Messtechnik GmbH located in Wiesbaden Germany, formally a group within Heimann Optoelectronics, has been designing and manufacturing non-contact infrared thermometers for close to 50 years. 

100% adherence to specifications during final inspection and burn-in tests is required for each instrument. Calibration is traceability to the German national metrological institute, PTB, to ensure high product quality.

HEITRONICS Infrared Thermometers are designed to meet the highest demands and standards of its customers, who are themselves technical leaders in their respective industries. Heitronics' unique and patented chopped radiation method eliminates thermal drift and compensates for thermal shock. The resulting stability from this method, combined with sophisticated noise reduction signal processing circuits, ensures the instruments' excellent performance.

In general, HEITRONICS instruments excel in difficult measuring applications, applications characterized by small targets and fast response times over wide temperature ranges, often with high repeatability requirements. HEITRONICS Radiation Thermometers are unequalled in their NETD temperature resolution, optical resolution definition, high stability, accuracy, fast response and being available in the greatest variety of spectral ranges. 




HEITRONICS is committed to providing "world class" advanced infrared sensing equipment for non-contact temperature measurements in professional applications.




IR Overview

Infrared thermometers measure the temperature of an object without touching it. Typical applications for non-contact temperature measurement are when the measured object is small, moving or inaccessible, has low thermal conductivity or too fragile to touch; or for dynamic processes that require fast response. 

Most of the well-known thermometers (e.g. glass bulb mercury or alcohol, thermocouple, or RTD) must be placed in direct contact with the temperature source. In contrast, infrared thermometers determine the surface temperature of an object by receiving the infrared radiation it emits at distances that can vary from a fraction of an inch to several miles in airborne applications.

The underlying principle of Infrared Thermometers is based on the fact that all objects emit radiation at wavelengths in the infrared region of the electromagnetic radiation spectrum. Infrared radiation lies beyond the visible response of the human eye. (blue to red, 0.4 to 0.75 μm).  Infrared thermometers process this radiation and provide an output signal(s) calibrated proportional to temperature.


For years, HEITRONICS' Radiation Pyrometers have been the most frequently selected radiometers for airborne remote sensing.  On July 1, 1997, a HEITRONICS system was the first commercial infrared pyrometer to be part of a scientific experiment in the "Columbia" spaceshuttle SpaceLab project.
