Description
This blackbody source is particularly suitable for
the calibration of thermal imagers.
It comprises a heat / cool ridged blackbody
source of 70mm diameter whose temperature
can be set from 20°C to 45°C to a resolution of
0.1°C.
Features
Combined stability / accuracy of ±0.2°C using
contact thermometry.
Emissivity is better than 0.97 ± 0.02.
Evaluation at Land Pyrometers showed the
advantages of fitting a stainless steel tube
around the plate to give better uniformity and
less sensitivity to draughts and ambient
temperature effects.

Altering the Block Temperature, (Setpoint)
1. Switch the unit on. The power switch is located
on the front panel.
2. After Power Up the nominal temperature will
be shown on the display.
3. To display the set point (the desired
temperature) press Þ.
4. To increase the set point: Press Þ ▲together.
5. To decrease the set point: Press Þ ▼together.
The other controller functions are hidden from the
operator. The values are pre-set and should not be
changed.
