Heitronics KT15 IR temperature sensor (number 1) is a digital, compact, programmable and universally applicable radiation pyrometer series with comprehensive and flexible functions for industrial temperature monitoring and control. It measures surface temperature remotely from infrared radiation.

The KT15.85 IIP model is able to measure between -25 and 200 °C.

Data are measured and outputted at 1Hz.

It features:
- Extreme high stability due to Chopped Radiation Method
- Very high resolution 0.03 °C
- Fast response times from 5 ms on low temperatures
- Very high linearization accuracy (0.02K)
- Fields-of-view from 0.7 mm at low temperatures allow high optical resolutions
- Permanent self-monitoring routines ensure a reliable operation
- Integrated calibration routine allows for fast and reliable control of the device.

These data were collected as part of the joint Natural Environmental Research Council (NERC) and US National Science Foundation (NSF) -funded Integrated Characterisation of Energy, Clouds, Atmospheric state, and Precipitation at Summit - Aerosol Cloud Experiment (ICECAPS-ACE) project.
