GRAETZ CE-Telescope

With the GRAETZ CE-Telescope, measurements of dose rates & pulse rates can be performed from a safe distance. Even measuring locations that are difficult to access can be reached more easily with the stainless steel telescope. The telescope can be equipped with a wide variety of measuring probes from GRAETZ. There is also the possibility of an easy connection with the dose rate meters of the GRAETZ-X5 series.

Product Highlights

GRAETZ CE-Telescope

Large operating radius for safe measurements

Sturdy stainless steel telescope with a robust housing

Safety through practical application of the quadratic distance law in radiation protection

Different measuring ranges selectable by plug-in probes from the GRAETZ probe program

Can be combined with the dose rate meters of the GRAETZ-X5 series

  • For measuring high dose rates/pulse rates from a safe distance
  • For measurements in poorly accessible measuring locations
  • Easy connection with the X5C plus SE, X5C FW dose rate meters and the X5C plus calibratable dose rate meter via contact row using snap-in technology
  • Safe connection of telescope and base unit without plug or cable (only via contact row)
  • Telescope made of stainless steel, continuously extendable up to 4 m total length
  • Torsion-proof connection between measuring head and electronics through internally routed ribbon cable
  • Automatic measuring range switchover
  • Display of dose rate at the operator’s location at the push of a button
  • Voltage supply from the dose rate meter
  • Energy range, measuring range, measured variable correspond to the data of the respective connected probes

Note for use by fire departments:

  • Possibility of connecting the X50ZS dose rate meter by means of a special adaptation module

Energy range, measuring range, measured variable correspond to the data of the respective connected probe.
