Technical Indicator:

Detector: GM counter tube (with energy compensation)

Measurement range: cumulative dose equivalent: Hp（10）0.0 μSv ～ 99.99 mSv

Dose equivalence rate: Hp（10）0.1 μSv/h ～ 99.99 mSv/h

Relative error:<±15%（¹³⁷Cs）

Energy response: 48 keV ～ 1.3 MeV, error ≤ ≤ ± 30%

Angular response: The reference ¹³⁷Cs should not exceed ±30% of the response in the calibration direction at 0°to 90 °

Alarm function: This instrument now has a fixed alarm threshold of 50 μSv and 25 μSv/h, when it is greater than the set alarm threshold, there will be an audible and visual alarm. When the counter tube is blocked, there will be continuous alarms, and the alarm sound intensity will be greater than 80 dB at 30 cm.

Power consumption: Two AAA 1.5V alkaline batteries (No. 7 battery) in an environment with a power consumption of less than 2 mW and continuous use for 720 hours

Boundary dimension: 55 mm × 92 mm × 18 mm (width × long × Thick)

Weight: 98 g

Functional Characteristics:

The instrument has high sensitivity and is also responsive to environmental background

Low power consumption:<2 mW

Strong resistance to electromagnetic interference

Main Purpose:

Suitable for the protection and personal dose monitoring of workers in industrial non-destructive testing, isotope applications, nuclear industry, hospitals, railways, civil aviation, environmental protection and other radioactive application fields.
