Product performance:
RAY-3000A ray alarm device
1, low power consumption, the background can work continuously for 20 days
2, measuring the dose rate of radiation, showing dose rate, cumulative dose and storage cumulative dose
3, with a cumulative dose storage function, data can be permanently saved after power is not lost
4, a variety of dose rate alarm threshold to choose from
5, there are regular alarm, continuous alarm, mute alarm three modes for users to choose
6, high sensitivity, more accurate and reliable measurement
7, small size, easy to carry
8, the instrument operation is more simple, more convenient to use
9, with imported CR2450 button batteries, and more security and environmental protection

Technical Parameters:
The G-M counter is compensated for low energy response.
Instrument sensitivity, the environment will have a response to the background.
For radiation occasions γ, χ ray.
Measuring range: Dose rate: 0.01μSv / h-999.99mSv / h
5 liquid crystal display 0.01μSv-99.99mSv / h
Able to ring: < ±30% (50Kev—1.3Mev)
Relative basic error: < ±10% (137Cs )
Dose rate threshold alarm: alarm threshold is 0.5, 1.0, 2.5, 10, 30, 50μSv / h.
The instrument has a cumulative dose storage function. Power after the memory data can be permanently saved without loss, can be 100 million storage erase.
Working environment requirements: Temperature: -10 - +50 ℃ Humidity: 90% (no condensation)
