HUATEC FJ-3501 Personal Dosimeter

Product introduction:

FJ-3501 Personal Dosimeter is a smart pocket instrument that monitors x-rays and γ rays and can read individual doses and individual dose rates directly. Within the measuring range, the alarm threshold can be fixed or preset, and a sound and light alarm will be issued when the alarm threshold or block is blocked. The product implementation standard is "JJG 100-2006 direct reading X, γ radiation personal dose equivalent (rate) monitoring instrument”. A production license for manufacturing measuring instruments.

Technical parameters:

Detector: GM counter (compensated)

Measurement range: cumulative dose equivalent: Hp(10)0.0μsv-9999msv

Dose equivalent rate: Hp(10)0.1μSv/h-100mSv/h

Relative error: ＜±15% (137Cs) (10uSv/h-50msv/h)

Energy response: 50KeV-1.3MeV, error of 30%

Angle response: the reference 137Cs does not exceed the calibration direction of ±30% at 0°-90°

Alarm function: the alarm threshold can be set continuously, the alarm valve value is greater than the set alarm threshold. When the counter is blocked, continuous alarm is constant, and the alarm sound intensity is greater than 80dB at 30cm.

Power consumption: a 1.5v alkaline battery section (no. 7 battery) environment under the environment, continuous use of 72 hours, power consumption ＜ 3mW.

Appearance size: 50 (style)×72 (long)×14 (thick)

Weight: 60g

Performance characteristics:

Small size, light weight, with back clamp, easy to carry

The sensitivity of the instrument is high, which also has a response to the environment background. Overload blocking alarm

Use a common battery, low power consumption

Strong resistance to electromagnetic interference

Application field:

It is applicable to the protection and personal dose monitoring of workers in the fields of industrial nondestructive testing, isotope application, nuclear industry, hospital, railway, civil aviation, environmental protection and other radioactive applications
