MT3900 High Sensitivity Personal Radiation Alarm Dosimeter For Radiation Occasions γ,  χ , βrays

MT3900 personal radiation alarm dosimeter

Description:

MT-3900 personal radiation alarm dosimeter is a kind of small-sized portable equipment, which is made by 

new single-chip microcomputer technology. With its anti-interference performance, it is mainly used to detect

 χ-ray, γ-ray and β-ray even under bad working conditions, “radiation rate” and “accumulating radiation dose” 

can directly be read on its LCD screen. The threshold limit can be fixed for alarming, it alarms to prevent 

persons from being injured by the over dosed radiation. MT3900 is widely used in NDT, nuclear power station, 

nuclear submarine, isotope application and hospital cobalt treatment etc.

Specifications:

• Through G-M counter compensation, improve the low-energy response.
• Instrument with high sensitivity, will respond to the natural environment.
• For radiation occasions γ, χ ,βrays.
• Measuring range, dose rate: 0.000usv/h—5msv/h
• Accumulated dose: 6-digit LCD display 000.000—999.999msv
• Energy response: <±30% (50KeV—1.3MeV).
• Relative basic error: ＜±10%(137Cs Source 662 KeV γ Radiation 1msv/h).
• Alarm response time: ≤3 seconds.
• Alarm function
• Dose rate threshold alarm: alarm threshold value: 0.5,1.0,2.5,10,30,50usv/h.
• With accumulated dose memory function, after power-failure, data can be stored permanently, it can undertake 1 million times storage and erased.
• Battery voltage indication. 
• Icon shows the battery voltage in the upper right corner of Instrument LCD, when battery shows three full grids, power is about 2.8V-3.2V, when battery shows two grids, the power is about 2.5V-2.8V, when battery shows one grid, the power is about 2.1 V-2.5V, when battery shows without grid , the power is under 2.1V, it is in the state of less power.
• Working environment requirements:
• Temperature:-10 - +50℃ Humidity: reach 90% (no condensation)
• Weight:130g (not including battery )   
• Size: 150mm x 73mm x 31mm

Features 

1). sensitive, stable. 

2). Super LCD English display.

3). “radiation rate” and “accumulating radiation dose” can be directly read, testing time is chosed by the 

radiation rate and the precision, normally is 30s, 60s is chose when the radiation rate is low.

4). Natural enviroment test is specially designed to check whether the equipment works regularly, it is also 

convenient for self-checking and examinating by measuring organization .

5). Low consumptive, portable.

6). Simplely to operate.

Competitive Advantage:

• High sensitivity, stable and reliable.
• Super LCD English display functions, state display at a glance.
• When measuring radiation dose rate, display dose rate, accumulated dose and storage accumulated dose, it has variety of selections on dose rate Alarm threshold. According to the high-low of dose rate and accuracy choice the measure time, general measure time is 02s. When measure relatively small doses, please select 10 or 20 seconds.
• Specially designed the nature test function, it can test if the equipment works  normally, convenient to self-check and measuring department examination.
• With accumulated dose memory function, after power –failure, data can be stored permanently, and don’t lost.
• Low power consumption, multi-function, small size, convenient taking.；
• Simple operation and easy to use.
