identiFINDER R400 (Formerly IdentiFINDER 2)

The world’s leading, smallest, and lightest handheld radiation detector

The R400 is a logical next generation instrument greatly based on the original identiFINDER. With 15,000+ identiFINDERs deployed worldwide inputs on how to improve this already excellent instrument have been few but valuable. The R400 is the result of taking these inputs and suggestions and adding them to the original instrument. The R400 uses the same algorithms that have proved themselves over many years of superb operation. The housing and three button, one hand operation is also the same. Following is a listing of the features added to make up the R400:

  • Extended 5 year service interval
  • Improved communications with industry standard Bluetooth and USB connections
  • New transflective color display, viewable in all lighting conditions
  • Storage for 600,000 spectra and GPS for location recording
  • No proprietary software used, simplifying customizing instrument settings and downloading industry standard n42.42 files.

The R400 is able to rapidly detect, quickly locate, accurately measure and precisely identify gamma emitting radionuclides.

The ability to detect gamma sources as well as the presence of neutrons in the radiation field via an optional neutron detector enhances the identiFINDERs capability.

The standard R400 includes a 1.4” (35 mm) diameter x 2” (51 mm) long NaI (Tl) detector plus a GM tube for high gamma dose rate measurements. Instruments are supplied with a carrying holster plus a wrist strap, serial cable, battery pack for rechargeable and non-rechargeable batteries, charging unit and a carrying case with shoulder strap. An optional, sealed 3He neutron detector can be added for neutron detection. The identiFINDER R400 is also available in fully submersible housing. Variations in operating conditions can affect the performance of radio-isotope identification devices (RIID) with scintillation detectors. Changes in temperatures or high count rates can cause measurements to shift impacting the peak positions and the instrument’s ability to ID accurately. The R400 automatically corrects for these changes by calibrating at start up and continuously stabilizing the measure through the use of an small internal source or our patented LED stabilization technique.
