Photometric Sensors

  • Product No:211 / 263 / 268P / 424
  • Manufacturer:Gamma Scientific

UDT Instruments offers a wide range of photosensors for both photometric and radiometric applications. Basic sensors, used alone, are suitable for illuminance or irradiance measurements. Each type of sensor can be combined with various types of optical adaptors to form sensor head assemblies suitable for measurements of flux, intensity, luminance, or radiance.
