Radiation Alert Ranger Exp Geiger Counter provides optimum output in a lightweight, versatile approach for using your survey meter in laboratory or field harsh industrial environments. This provides outstanding exposure to low levels of Alpha, Beta, as well as Gamma and X-rays, with its oversized, pancake type GM pipeline. The survey meter for the EXP is now smaller, more ergonomic, and has better features, all at the same price! The Ranger EXP features a new touchpad technology interface and includes an integrated, protective boot with each instrument at no extra charge.
Features of Radiation Alert Ranger Exp Geiger Counter:
- Micro, hand-held instrument based on microprocessors
- Excellent exposure to weak Alpha, Beta, Gamma, and X-ray rates
- Digital display with a backlit view
- Red Light Counts
- Audible Beeper sounds with each detected count, giving instant indications of the level of radiation.
- Choose Alert Levels
- Timer adjustable to perform Timed Counts
- Built-in efficiencies to calculate activity in the Bq and DPM for common isotopes. (Important: The Ranger does not recognize any isotopes-you must know the isotope in advance to use this feature).
- Data storage, internal memory, and USB networking
- Free USB Observer program to download your files, set alarms to your device, and calibrate your instrument!
