Besides the UV measurement value the ZED TinyMeter enables access to sensor specific data: sensor-ID, operating hours and date of last adjustment/calibration. Exceeding the specified operating hours of a connected reference sensor is indicated in the display.


  • UV-C Reference Radiometer use with ZED Reference Sensors D-SiCONORM-LP-REF for checking DVGW and ÖNORM compliant plant sensors
  • optimized for cost sensitive applications
  • simplified usage, base functionality
  • alphanumeric display with dynamic resolution and backlight
  • protected against dust and streams of water (IP65)
  • low power consumption / long operation time with normal alkaline battery
  • connects to ZED D-SiC UV sensors with RS485 interface (types with measurement in W/m², production date starting 2017)
  • The measurement range is defined by the connected sensor, the TinyMeter does not have to be recalibrated.
