Digital Sensor D-VUV 185nm for 185nm measurement back
  • The digital sensor D-VUV 185nm is intended to be used for checking ozone producing low pressure mercury UV lamps. The measurement is performed in air, the sensor front is placed directly on the lamp surface.
  • The sensor comprises a highly sensitive and stable phototube with spectral response between 120-220nm and extremely low response at 254nm.
  • The sensor is designed for use in dry rooms under laboratory conditions. It is not suitable for continuous operation and should not be operated in direct contact to the hot lamp surface for more than 30 minutes.
  • The digital sensor D-VUV 185 features digital signal processing. The measured value is internally converted into a digital signal according to ZEDs special ZCON protocol. Via RS485 this signal can be visualized using a suitable displaying system like the ZED SmartMeter or the PC software ZED Sensor Configurator.
    The designation of the measurement values is dimensionless in 'digits'.
  • Use the Sensor fastener F01 for correct mounting and repeatable positioning of the sensor at the lamp.
