SR-200N High Emissivity Blackbody

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