P300 Blackbody Radiation Calibration Source
Blackbody Calibration Source Design Achieves An Emissivity of 0.999 or Better Pyrometer Instrument Co Inc., Northvale, NJ – Introduces its new P300 precision blackbody calibration source. The P300 has a 51mm (2.0)" aperture opening and employs a uniformly heated spherical shaped cavity that achieves a near ideal emissivity value of 0.999 or better over its entire temperature range. The P300 will provide any temperature between 100°C-1200°C (210°F-2190°F) accurately to ±0.25% of reading ±1°C. (Accuracy calibration performed radiometrically, the uncertainty of emissivity and transfer standards are already included.) The P300’s accuracy is traceable to the National Institute of Standards and Technology (NIST). A certificate of calibration is supplied with the unit. The P300’s utilizes a microprocessor based, self-tuning digital PID controller to display and hold the operator selected temperature to within±1°C. An optional RS422/485 serial communications port is available to allow the current displayed temperature and set point temperature to be output to an external PC or controller. The P300’s requires only a 1 hour warm-up time from room temperature to 1000°C and can be operated at ambient temperature ranging from 0°C-44°C (32°F-110°F). The P300 is fan cooled with the air inlet on the back of the unit’s enclosure. Optional accessories include a water-cooled aperture wheel assembly to reduce the size of the aperture opening and a universal-mounting flange. Applications include calibration of infrared thermometers, heat flux meters, radiometers, thermal imaging systems and spectrographic analyzers.
