PSC BBS-FP Fixed Point Temperature Calibration Sources

The PSC-BBS-FP Series

The BBSxx-FP Blackbody series provides a quick and accurate way to check the calibration of non-contact infrared temperature sensors. Eighteen Blackbody calibration source models are available; offering fixed target temperatures from 35ºC to 150ºC, all providing outstanding stability with less than ±0.2ºC deviation.



The Blackbody emitter heats up and stabilizes in 5 to 15 minutes to the desired temperature, depending on the model. An LED indicator on the Blackbody is used to show when it has reached its final target temperature:  green when the BBS…FP is warming up, orange when the BBSxx-FP is ready for operation and red when the BBSxx-FP is overheating (visual warning alarm).

The BBSxx-FP can be used with any infrared temperature sensor that is able to measure between 35ºC and 150ºC and can focus on a target area less than 2” (50.8 mm).

The PSC-BBS-FP series is avalible in the following fixed temperature points:

  • BBS35-FP             Calibration source BBS35              35 °C
