FLIR identiFINDER R400
Operators use the handheld R400 to detect, quickly locate, measure, and identify the source of radioactive material. Teledyne FLIR describes it as the most widely deployed handheld radiation detection and identification product in the world.
The ideal balance of size and weight for a wide variety of monitoring scenarios.
- All-purpose surveying
- Emergency response
- Environmental monitoring
Field-proven, tried and true
The R400 is a handheld RID in the identiFINDER R-series. Teledyne FLIR puts it at over 20,000 devices deployed globally and calls it the most trusted RID in the world. It shares a common operating interface with other identiFINDER R-series products, which Teledyne FLIR says reduces training time and costs.
- 01
Over 20,000 deployed globally
Teledyne FLIR’s summary: “Over 20,000 deployed globally for tough, tried-and-true performance.”
- 02
One interface across agencies
The common operating interface reduces training time and costs, while increasing operator confidence and inter-operability between agencies.
- 03
Sized for stressful work
Teledyne FLIR states that at half the size and weight of competitive RIDs, the R400 helps operators feel comfortable using the instrument even in the most hazardous and stressful environments.
- 04
Rugged and mission-ready
Built for fast front-line detection and response, in an aluminum housing weighing ≤3.2 lbs (≤1.5 kg).

“Same tried and trusted interface as the R400. Pick it up and go.”
Detect. Locate. Measure. Identify.
One handheld covers the whole sequence, from the first alert to a nuclide identification. The scintillator covers dose rates up to 500 μSv/h, and a back-up Geiger-Müller tube provides detection capability even in high dose rate environments.

Step 01
Detect
Rapid visible, audible, and tactile alerts that expedite response measures.
Energy range (gamma)20 keV - 3 MeV -
Step 02
Locate
Quickly and efficiently close in on the source of radioactive material.
Scintillator dose rate range0 nSv/h - 500 μSv/h (0 nrem/h - 50 mrem/h) -
Step 03
Measure
Back-up gamma detector provides detection capability, even in high dose rate environments.
Geiger-Müller dose rate range100 μSv/h - 1 Sv/h (10 mrem/h - 100 rem/h) -
Step 04
Identify
Identifies ANSI N42.34 library, with high resolution and low false alarms.
Sampling & analysisFrom a few seconds to minutes
Identification you can read
Nuclide identification follows ANSI N42.34. The R400 stores up to 600,000 spectra in 2GB internal memory, and the large, color display eases data interpretation.
Choose the crystal, the radiation, the housing
The R400 comes in ten product variants. Teledyne FLIR describes NaI or LaBr detectors for custom sensitivity and resolution, gamma-only or gamma and neutron models, and an underwater model. Two variants use a tungsten-shielded NaI detector.

Ask about configurationsAlerts that move the decision forward
Like other identiFINDER R-series products, the R400 contains on-board Bluetooth, web server, and GPS technologies, so important tactical information is easy to transfer.
Visible, audible, tactile
Rapid visible, audible, and tactile alerts expedite response measures.
Large color display
A transflective color LCD eases data interpretation.
GPS, webserver, Bluetooth
On-board GPS, webserver, and Bluetooth capabilities, with onboard webserver software.
Fast two-minute startup
<2 mins from cold start. Either rechargeable NiMH or 4x AA pack (supplied), with ≥8h operational battery life.
Short to train
Training requirements: <10 mins for operator; 1 day for advanced user. The common operating interface reduces training burden.
