Real Time Radon Thoron Monitor For Air Soil Water Radon Testing Device

DA-Ra01 real-time radon monitor for air, soil, water

 Product introduction 

DA-Ra01 real-time radon monitor is a radon testing device that do real-time and micro pump automatic continuous sampling of radon gas in air, soil and water. It uses a micro pump combined with static electricity to collect radon decay radon progeny RaA As the measurement object, it meets the sampling and measurement method requirements of GB/T 14582-1993, and quantitatively measures the radon concentration in soil or air. It has high sensitivity, easy operation, overcomes the inconvenience of manual sampling and external interference factors, and measures and gives results in real time. The measurement time can be set within 1-120 minutes according to the level of radon. It is the most automated instrument for soil radon detection in China. It meets the requirements of soil radon measurement in GB50325 "Code for Indoor Environmental Contamination Control of Civil Construction Engineering" and is widely used in civilian use. Construction engineering, radioactive ore prospecting emanation measurement and water radon concentration determination for hydration ore prospecting can also be used for radon level investigation and radon prevention and radon reduction research in departments such as searching for groundwater sources, earthquake forecasting, environmental protection engineering, scientific research and teaching. It meets the verification requirements of JJG825-2013 "Radon Meter".

Features

• Built-in measuring chamber with a volume of 0.8L

• The pump suction electrostatic measurement method is adopted, and the sampling flow rate is controlled at about 1L/min by a micro vacuum pump system;

• Desiccant is used at the sampling point to eliminate the influence of humidity on the measurement;

• The detector adopts highly sensitive α-particle semiconductor devices, which can convert α-particle rays into electronic signals, collect and amplify electricity through static electricity.

The amplitude of the electronic signal is measured by means of a circuit, thereby identifying the energy of the incident alpha particle;

• The instrument can accurately measure Po-218 particles produced by indoor radon decay, with good energy resolution and high detection efficiency.
