Black Body
Tempsens offers an advanced range of black body calibrators designed for accurate, stable, and traceable infrared sensor calibration across a wide temperature range. Whether you’re validating industrial pyrometers in a steel plant, thermal imagers in aerospace R&D, or field instruments on-site, our solutions deliver high-emissivity, low-drift, and repeatable performance every time.
From low-temperature black body sources to high-temperature black body calibration sources, Tempsens is trusted by metrology labs, manufacturers, and system integrators as a leading black body manufacturer and supplier across the globe.
Extended Area Black Body
Extended Area black body is specially designed with the large emitting surface area and precise temperature control with good uniformity.
High Temperature Black Body Furnace
These calibrators can be used in many Process Industries, R&D institutions and laboratories for high temperature calibration.
CAL FAST BB
CAL FAST 400 BB offers a medium temperature range from 50 to 400°C. It is a highly stable standard black body calibrator for calibrating non-contact type sensors like Pyrometer/IR Thermometers.
Dual Black Body Temperature Calibrator
Extended area black body is defined by the large emitting surface area precise temperature control with good uniformity. Tempsens make Blackbodies are state of the art, highly accurate, and stable with different standard sizes and temperature ranges.

About Tempsens Black Body Calibrator
Understanding How a Black Body Furnace Works
A black body temperature calibrator is a thermal radiation source that emits uniform infrared energy at a known temperature and high emissivity (typically ≥ 0.95 ). This consistent radiation output is used to calibrate IR thermometers, thermal cameras, and pyrometers.
The blackbody calibrator includes:
- A heated cavity (cylindrical or conical)
- PID Temperature controller
- Insulated enclosure to maintain stability
Black Body Furnace follows Planck’s Law, producing radiation proportional to the setpoint—ideal for infrared black body calibrator applications.
