SR-800N: Extended Area Blackbody

Extended Area Blackbody ControlMaster

Download Brochure

CI Systems’ ControlMaster SR-800N sets a new standard for accuracy and uniformity in blackbody technology.

Temperature measurement and calibration are performed in the radiation head and then transferred digitally to the ControlMaster controller.

The result is accurate, stable, reliable, and NIST-traceable (*).

System Calibration

Temperature is controlled by easily-removable, user-replaceable sensors.

Our factory-supplied replacement sensors provide an efficient means for recalibrating the system, providing an additional 12 months of service.

Alternatively, customers may recalibrate the blackbody with our optional CK-800R.

Notes (for pages 2-3):

All values are valid at an ambient temperature of 22 °C in a non-condensing environment
Uniformity values are for a ±1 °C step from ambient temperature over 80% of the central area. For other temperatures multiply by ΔT
Accuracy is referenced to a NIST-calibrated CI Systems master sensor
LT models include a refrigerator (power consumption depends on the model)
Typical yearly drift: 02 °C
Total system uncertainty: 02 °C @ ΔT < ±25 °C and 0.03 °C @ ΔT > ±25 °C
Differential temperature range is limited to the absolute temperature range,

and absolute temperature range is limited to the differential temperature range.
