FH 40 TG Telescopic Probes

FH 40 TG Telescopic Probes

Measure dose and dose rate at a secure distance for all situations where an extended range is required or high radiation may occur with the Thermo Scientific™ FH 40 TG Telescopic Probe, which attaches to the Thermo Scientific™ FH 40 GL Digital Survey Meter.

Simultaneously determines dose and dose rate measurement at the operator end while measuring dose rate at the teleprobe end


  • Features a built-in speaker and the ability to log up to 256 measurements for later retrieval by a PC via infrared serial interface
  • A large backlit digital display with an analog graph and menu-driven operator functions facilitate a user-friendly interface
  • Modular design allows easy exchange of components
  • Extendible up to 4m (approx. 13ft.)
