FD-3013B environmental gamma radiation monitor  

Features:

High sensitivity: the NaI (TI) crystals as detecting element. Easy to operate, Chinese LCD display, a second display a measuring results, alarm threshold choice and display unit: mu Sv/h. Has the battery voltage under-voltage and did not answer the probe tip alarm function.

Technical indicators:  

1, the detector: 30 x 25 mm, NaI (TI) crystal  

2, sensitivity: 350 CPS/mu Sv  

3, sensitive threshold: 40 kev  

4, measuring range: 0.01-200 mu Sv/h

5, reading showed: the five figures to mu Sv/h for the unit of measurement results is given

6, alarm threshold: there are four options: 0.25 mu Sv/h, 2.5 mu Sv/h, 10 mu Sv/h, 20 mu Sv/h  

7, battery under-voltage alarm: less than 2.2 v "please replace the battery" and sound

8, the accuracy of measurement, with a 95% confidence level, a reading: 0-10.00 mu Sv/h + / - 5% or less; 10-200.00 mu Sv/h + / - 10% or less

9, measuring time: conventionally, measurement time, every second, according to the current average for 3 seconds  

10, power: 200 mw or less  

11, using the environment: - 10-50 c + c (400 c temperatures), 98% relative humidity limit condition, the relative error of 10% or less  

12, weight: 1.2 kg
