- High accuracy ±0.2% of reading ±1 °C
- High emissivity 1.0 effective @ 0.7 ... 1.8 µm T>=230°C, 1.0 @ 8 ... 14 µm T<230°C
- Manufactured and tested to meet rigid quality control standards
- Furnished with certificate of calibration traceable to NIST
- RS232 (standard) or RS485 (optional) serial communications port
Details
The M305 blackbody calibration source uniquely combines portability with wide temperature range, high emissivity and high accuracy. It is an ideal calibration unit where portability is required or where installation space is limited. Its spherical, metal cavity design yields an emissivity of 0.995 over the temperature range of 100 to 1000 °C (212° to 1832 °F) with an aperture of 25 mm (1”). An integrally mounted PID controller adds to the unique versatility of this calibrator.
Quotations for custom designs and variations are available upon request.
