Geiger-Mueller counter for point level detection with separate transmitter

The Gammapilot FTG20 is the world’s most advanced Geiger-Mueller counter with highest available sensitivity and outstanding features. Even under extreme process conditions like high pressure, high temperature, corrosiveness, toxicity and abrasion, the radiometric measuring principle can be employed without any problems.

  • Benefits

    • Sensor and transmitter: One instrument for all measuring tasks - can be used universally due to numerous certificates and approvals

    • Highest availability, reliability and safety, even for extreme process and ambient conditions

    • No recalibration after...

  • Field of application

    For liquids, solids, suspensions and sludges etc. Particularly for applications under extreme measuring conditions, e.g. high pressure, high temperature, corrosiveness, toxicity, abrasion. All kinds of process vessels, e.g. reactors, autoclaves,...
