Features: 

1. Monitor of X, r and hard β ray. 

2. The instrument enjoys a high flexibility and can measure the environmental background. 

3. Chinese and English operational interface. 

4. Real-time measurement and display of dosage rate and accumulative dosage. 

5. Permanent data storage upon power cutoff. 

6. Graphic LCD and maximum screen. 

7. Low power consumption and battery under-voltage indication function. 

8. The instrument can preset the alarm valve value of dosage rate and accumulative dosage. 

9. Three selective alarm modes: sound, light and vibration.
