Electronic Personal Dosimeter NFR51

Product catalog summary

Overview: The NRF51 is an all-in-one electronic personal dosimeter designed for measuring X, γ, and neutron radiation. It features an emergency call button, a large backlit LCD display, and integrated communication and telemetry functions.

Specifications:

Reference Standards: IEC61526 Ed.3.0 and ANSI N42.20.
Radiation Measured: Hp(10) for X-rays, Gamma (γ) radiations, and Neutron.
Detector: Silicon semiconductor.
Measurement Range: For γ (X) rays, dose range is 1 µSv to 10 Sv and dose rate is 0.1 µSv/h to 10 Sv/h. For Neutron, dose range is 10 µSv to 10 Sv and dose rate is 1 µSv/h to 10 Sv/h.
Display Range: Matches the measurement range for both γ (X) rays and Neutron.
Energy Range: γ (X) rays from 30 keV to 7 MeV; Neutron from 0.025 eV to 15 MeV.
Energy Response: γ (X) rays ±20% (50 keV to 6 MeV); Neutron ±50% (250 keV to 4.5 MeV).
Angular Response: γ (X) rays ±20% (137Cs, 0° to 75°); Neutron ±30% (241Am, 0° to 75°).
Accuracy: γ (X) rays ±10% (137Cs); Neutron ±15% (252Cf or 241Am-Be).
Dose Rate Linearity: γ (X) rays ±10% (137Cs); Neutron ±20% (252Cf or 241Am-Be).

Display and Alerts:

Dot LCD (128x48) with a view area of 43.5mm x 16.3mm.
LED indicators: 3 red LEDs and 3 auxiliary LEDs (green, orange, red).
Buzzer: Piezzo-electric buzzer (90 to 100 dB @ 30cm).

Communication and Data Storage:

Communication options include USB, Infrared, Electromagnetic induction, Bluetooth, 900Mhz radio, or Wi-Fi.
USB Interface: USB2.0 micro-B for power supply and communication.
Data Storage: Up to 4000 trend data entries and 1000 entry/exit data entries.

Power and Environmental Specifications:

Battery: Two primary AA (LR6) batteries with a life of 2500 hours (without alarm/communication).
Operating Temperature: -10°C to +50°C.
Operating Humidity: ≤ 95%.
Waterproof: IP65/67.
EMC: MIL STD 461F.

Physical Characteristics:

Dimensions: 60 x 105 x 29 mm.
Weight: ≤ 100g (without battery); approx 170g (with 2 batteries).

Additional Features:

Vibrator, Emergency call button, Thermistor for temperature compensation, External battery via USB-micro B port, Accelerometer.
