Product Description

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.

FJ-3501 personal dosimeter is operated by a single machine. The dose and dose rate data can be read directly by LCD. Within the measurement range, all kinds of threshold alarm values can be set arbitrarily, and sound and light alarm will be issued to remind the staff to pay attention to safety. The instrument is equipped with alarm of dose and dose rate exceeding threshold, alarm of working overtime, alarm of detector block, alarm of battery undervoltage and alarm of memory gradually full.

Personal dosimeter FJ3501 type main technical indicators meet the national standards and international standards, is the current domestic similar instruments in the strong function, small volume, low power consumption with a pocket instruments, it is widely used in nuclear military industry, nuclear power plants, industrial nondestructive flaw detection, isotope application and cobalt hospital treatment, occupational protection, residents around the plant background radiation level monitoring and other fields.


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
