UV power meter

C9536 H9535 SERIES

null

The C9536/H9535 series are UV power meters that directly measure UV light at specific wavelengths. The H9535 (sensor head) uses a UV sensor (phototube) that ensures stable UV measurement over a long period of operation and is calibrated in combination with the C9536 (controller) based on national standards. The detachable sensor head contains a rechargeable battery for UV detection and data memory, allowing remote measurement such as on a belt conveyor or in locations where cable routing is difficult. In addition to external control via the RS-232C interface, an analog control is available for recording on a data recorder, etc.

Features

  • Absolute optical power monitoring (mW/cm2)
    Sensitivity-calibrated data at each wavelength (172 nm, 222 nm, 185 nm, 254 nm) is supplied with the power meter. We also append a Certificate of Calibration.
  • Detachable sensor head / remote measurement
    The detachable sensor head allows remote measurement on a conveyer belt of UV oven, etc.
  • Thin, flat sensor head: 14 mm thickness
    Allows the sensor head to be used closer to a light source.
  • External control: RS-232C
    The main unit has RS-232C interface for external control.
  • Stable performance at deep UV since no optical filters are used
    Specific UV light can be directly detected without any optical filter.
  • Wide light incident angle
    Acceptable light incident angle is close to cos θ, even without using diffusers.

Applications

  • Excimer lamp monitoring
  • Low pressure mercury lamp monitoring
  • UV light monitor
    ・ UV furnace (coating, adhesive, printing) ・UV cleaning, UV sterilization ・Improving surface characteristics
