Introduction

    DSHD-3017A radon
survey water detector is a new model meter, it replies static to collect the
first generation progeny-RaA of radon decay as measurement objects, can survey
soil or radon concentration in water quantitively.And has many features: no
detector pollution problems, no radon emanation effect, high sensitivity,
simple operation, site result gained (generally 5min, 3min fastest to complete
one point measurement, the efficiency improves near 10 times more than foreign
products), which is the most advanced soil radon detector at home.

Applications

Besides mineral, water prospecting and radon concentration
determination,you can use DSHD-3017A radon survey prospector
to soil radon detection and water source seeking in construction project, radon
measurement of department like earthquake forecast, EP and scientific research
teaching etc. And You can read counting rate directly and converse to Bg/m3
value after demarcating by authorized computation branch.

Technical
Parameters

1. Limit exploration sensitivity: £¼0.1
Bq(1Bq/L=0.27*10-10ci/L=0.27em)

2. Air pump sealing functions: when the pump ram is at 70mm, gas leakage
velocity is less than 20mm Hg/min.

≤φ26mm)

5. Background: ≤4 pulse/h

6. Counting capacity: 1~99999

7. Equipment display: pulse numbers, HV indicate mark, measurement indicates
mark, low voltage or voltage shortage indicates mark, date and time.

8. HV and measurement timing: several shifts in 0, 0.5, 1, 2, 3, 4, 5, 6, 10,
15, 25, 30min. Among them, 0min is manual measurement, that is HV or
measurement will last to manual.
