The LT2000 environmental grade X - γ dose rate meter is a radiation detection instrument that monitors the environmental level specific release energy (absorbed dose) rate generated by various radioactive workplaces and gamma radiation sources. It meets the requirements of high sensitivity and high range radiation detection, using large volume NaI detectors and energy compensated GM detectors. The instrument adopts a separate design of host and probe, supporting wired and wireless connections between the host and probe. The host can be used independently and can connect multiple radiation probes to meet various complex environmental requirements. The instrument adopts a high-capacity built-in lithium battery, so users do not have to worry about the power supply of the instrument.

Application scenarios

Can be applied to environmental radiation background detection by environmental protection departments, radiation testing of radioactive medical equipment, radiation testing of non-destructive testing equipment, measurement of background in the peripheral environment of nuclear power plants, radiation testing in the peripheral environment of irradiation equipment, entry and exit inspection and quarantine, radiation safety inspection, and nuclear counter-terrorism;

Functional Features

1. Adopting dual detectors that combine high sensitivity and large range characteristics.

2. Background automatic deduction technology, automatically updating the background upon startup.

3. Support spectral analysis function.

4. The sensor supports automatic calibration and calibration functions.

5. Peak capture function, automatically capturing the time of radiation peak occurrence and displaying the last occurrence time in snapshot form on the host display screen.

6. Real time display of radiation dose rate and automatic accumulation of dose storage.

7. The alarm threshold can be adjusted arbitrarily, supporting dose rate alarm and cumulative dose alarm.

8. Real time measurement values and alarm thresholds are displayed in the same coordinate chart, which is intuitive and easy to read.

9. Alarm methods: sound, light, vibration, and can be combined arbitrarily.

10. Alarm types: Supports over threshold alarm, detector blockage alarm, detector failure alarm, artificial nuclide alarm, battery undervoltage alarm.

11. Low power design, the whole machine supports continuous use for 72 hours after being fully charged once.

12. Alarm records can be viewed without loss in case of power failure.

13. Dot matrix LCD display, with a simple and intuitive operating interface.

14. Automatic backlight function, which automatically enhances the display backlight as the ambient light decreases.

15. The instrument is equipped with a large capacity memory, which can be used to store measurement records, alarm records, and will not be lost in case of power failure.

16. The instrument has an independent calendar time built-in, and can operate normally when the instrument loses power.

17. The host and probe can operate independently.

18. The host and probe can support wired and wireless connections.

19. The instrument adopts a Micro USB interface and is compatible with Android phone chargers, making charging resources readily available.

20. Silicone physical buttons provide a comfortable and good tactile sensation.

21. Data export: Supports USB data export.

22. Network interface: Supports Ethernet data interface.
