Kalibrierstrahler M300

Mid Temperature Range Blackbody Calibration Source

Großer Kalibrierstrahler mit sehr hohem Emissionsgrad zum wellenlängenunabhängigen Kalibrieren, Hohlraumstrahler, 200 ... 1150 °C

Kalibrierstrahler M300

Key Features

  • Superior accuracy within ±0.25% of reading ±1°C
  • Large 51 mm (2”) aperture diameter
  • High effective emissivity 1.0 at 0.7 to 1.8 µm, 0.998 typical at other wavelengths
  • Rugged housing designed for fixed installation in laboratory or test department
  • 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


A high standard, precision blackbody calibration source designed with a unique uniformly heated spherical cavity that achieves a near ideal emissivity of 0.998 or better.

The M300 will deliver any temperature between 200 °C and 1150 °C (392° TO 2102 °F) – accurately. A convenient microprocessor-based, self-tuning digital PID controller holds the selected temperature to within 1 °C, thus assuring high accuracy calibration.

Typical Calibration Applications

  • Infrared Temperature Sensors
  • Infrared Thermal Imaging Systems
  • Spectrographic Analyzers
  • Spectral Radiometers
  • Heat Flux Meters
