The CI Systems SR-200 is a highly reliable and durable cavity blackbody. The SR-200 unique design permits rapid warm-up and cooling. It's unique controller enables the addition of numerous options.The SR-200 operates using the controller's touch keys located on it's front panel and may also be controlled by a computer. In order to keep it's accuracy and NIST traceability, it is recommended to recalibrate the SR-200 yearly.
