Ultraviolet radiometer is a wide-spectrum power measuring instrument, which is mainly used to measure the radiant energy power density of UV light, that is, the radiant energy power per square centimeter.

1 UV Light Irradiance Meter

The unit of measurement is microwatts/square centimeters (μW/cm2). The detector is located on the front face of the instrument, which is convenient and quick to use, and reliable in measurement.

2 Main application areas

1. Architectural film, solar film, heat-insulating glass, etc. to the UV barrier performance test;
2. Radiation intensity measurement of ultraviolet sources (sun, ultraviolet lamps, etc.);
3. UV disinfection and curing;
4. Meteorological and agricultural production fields;

Parameter

  1. Measurement accuracy: ±(4 %FS + 2digit) FS: Full scale
  2. Spectral response, 260nm-380nm, center wavelength 365nm
  3. Range: ×1 (0-1999 uW/cm2); ×10 (2000 -19990 uW/cm2, multiply the displayed value by 10)
  4. Dimensions: Length 125mm × Width 68mm × Height 22mm
  5. The weight of the instrument is about 110 grams
  6. The battery is a standard 9V alkaline battery, model: 6F22

Instructions

  • Radiation intensity measurement of ultraviolet source (sun, ultraviolet lamp, etc.) When measuring the ultraviolet intensity of the ultraviolet source, the direction of the detector is facing the ultraviolet source, press the “POWER” key, turn on the instrument, and select the appropriate test range. Test the ultraviolet radiation intensity of sunlight reaching the ground, and the measured value is 712 uW/cm2.
  • Testing the UV-blocking performance of the solar thermal film, thermal insulation glass, etc. When testing the UV-blocking performance of solar thermal film or thermal insulation glass, the measurement should be divided into two steps:
  1. The first step: measure the radiation intensity of the ultraviolet source: The ultraviolet source can be sunlight or ultraviolet lamp, etc. First measure the ultraviolet radiation of the ultraviolet source. The radiation power density is UV1 W.
  2. Step 2: Measure the radiation intensity of the ultraviolet source blocked by the solar film:
    Keep the distance between the UV source and the instrument unchanged, insert the solar film or insulating glass to be measured between the instrument and the UV source, and the measured object must be close to the measuring end face of the instrument to avoid the influence of external light. Note the power density of ultraviolet radiation energy UV2 W when there is a solar film.
  • Then the UV blocking rate = UV2 UV1 100%-W /W
  • From the first step, UV1 W =372 μW/cm2
  • From the second step, UV2 W = 12 μW/cm2
  • UV blocking rate = UV2 UV1 100%-W /W =100%-12/372 = 96.77%

Precautions

1. When testing the UV barrier performance of solar film or heat-insulating glass, the distance of the light source should be the same in the two-step measurement.
2. For UV sources of different intensities, select the appropriate range.
3. When not in use, please press the “POWER” key to shut down.
4. When replacing the battery, you need to open the back cover, remove the old battery, and replace it with a 6F22 alkaline battery.
5. Avoid contact with corrosive materials and stay away from high-temperature and high humidity environments.
