　　The DURRIDGE RAD7 radon meter from the United States can not only measure radon in the air, but can also be equipped with RAD H2O and RAD AQUA radon accessories to measure radon in water. The SOIL PROBE soil probe can be used to measure radon in soil, and the SOIL COVER can be used to measure surface radon. the United States

　　The DURRIDGE RAD7 radon detector has obtained the National Type Approval Certificate for Measuring Instruments, with type approval number PA 2006-C262.

　　The portable radon detector RAD7 is a handheld radon continuous monitoring device produced by DURRIDGE in the United States. It can not only measure the concentration of radon in the air, but also

　　Radon, optional soil and water probes can simultaneously measure radon in water and soil. The following is a detailed introduction, standard configuration list, and optional accessories for radon detectors.

　　The RAD7 alpha spectrum radon detector from DURRIDGE Corporation in the United States is a handheld detector with the shortest response and recovery time, sniffing and continuous operation on the market. Easy to operate, follow the prompts of the microcomputer to display the measured radon and thorium gas concentrations in frequency spectrum curves, and output data using an infrared printer. By using a drying device to reduce the humidity of the sampled air, the accuracy of the detection results can be improved. You can set the sound emitted when counting radon and thorium gas to understand high pollution areas. Multiple accessory options are available for measuring radon in the air, soil, and water.

　　It only takes one hour to measure the 4pCi/L action level concentration specified by the US EPA.

　　According to the Metrology Law and relevant regulations and technical requirements, the RAD7 electronic radon meter from DURRIDGE Company in the United States has been tested

　　Qualified identification and obtain the type approval certificate for the measuring instrument. Type approval number PA 2006-C262.

　　Features of DURRIDGE RAD7 Radon Meter from the United States

　　The electronic radon detector with the fastest response and shortest recovery time is a portable detector that integrates continuous monitoring of radon gas and detection of radon radiation sources

　　Easy to operate, follow the prompts of the microcomputer to display the measured radon and thorium in spectral curves, and can output data using an infrared printer. Multiple measurements can be taken, including radon in the air, radon in water, and radon in soil

　　Provide fast and highly sensitive readings (0.5cpm/pCi/L)

　　Compliant with the 1-hour 4pCi/L operating standard set by the US EPA

　　By using a drying device to reduce the humidity of the sampled air, the accuracy of the detection results can be improved

　　The test results can be displayed, printed out, and downloaded on a computer

　　Lightweight and durable, equipped with a sturdy portable case, built-in sampling pump, RS-232 and USB serial ports, data download and analysis software

　　Standard configuration of DURRIDGE RAD7 radon detector in the United States:

　　RAD-7 host, power cord, shoulder strap and key, printer, 3 rolls of printing paper, printer adapter, 6 air intake filters, 1 dust filter

　　Device, 3 ethylene resin tubes, large drying tube, small drying tube, desiccant, built-in charging battery, PC data software and computer connection cable, Chinese and English user manual.

　　Optional accessories:

　　RAD AQUA Continuous Water Radon Accessories

　　By continuously pumping water samples into the RAD AQUA reaction chamber using a pump, radon gas will be released from the water, and with the help of RAD7, the radon concentration in the water can be continuously monitored. This device has very high sensitivity and low detection limit. By selecting remote accessories, users can even monitor and download readings in real-time from a distance.

　　RAD H2O water radon gas accessories

　　Collect water samples using 40ml or 250ml glass bottles, and use RAD7 to select the appropriate measurement protocol. The instrument will automatically run and obtain detection results. The sensitivity of 40ml and 250ml bottles is 0.008ppm and 0.05cpm per pCi/L, respectively. Suitable for spot check measurement of radon concentration in water

　　Water PROBE water radon detection head

　　This is an optional accessory designed for RAD7 to monitor radon concentration at specific water depths in wells, ponds, or rivers. The radon detection head in water is composed of a hose with a semi permeable diaphragm installed on a metal support frame. Especially suitable for environments with long-term static conditions and no water collection pump.

　　HS25L High Sensitivity Radon Gas Accessories in Water

　　Collect water samples using a 2.5L glass bottle, in conjunction with RAD7, select the sniffing mode measurement protocol, and the instrument will automatically run

　　And obtain the detection results. The detection sensitivity can be increased to 0.3cpm per pCi/L, which is suitable for measuring a very low concentration radon gas sample in water in a short period of time

　　Soil rod SOIL PROBE

　　Insert the soil rod into the soil of the testing site and use RAD7. The built-in pump will extract radon gas from the soil through the soil rod, allowing for continuous monitoring of radon concentration in the soil.

　　Radioum PROBE radium detection head, DRYSTIK drying tube moisture converter, Addender range extender, SOIL COVER surface radon detection accessories, etc

　　Before starting the measurement, place RAD7 in a dry, radon free atmosphere to clean the instrument's gas path for a period of time. During the cleaning process, use a large laboratory drying cylinder. And small drying rods are used for actual measurement. Connect a filter to the intake port of RAD7 first (refer to RAD7 operation manual),

　　Then connect the large drying cylinder to the filter. After cleaning the RAD7 air path in clean and dry air for 10 minutes, press[MENU] (Menu) key, then press twice[ENTER] (Enter the status window with the confirm button and press the right arrow key twice to check the relative humidity. If the relative humidity has not decreased to 6%, clean it for a period of time. In order to achieve effective drying, after the next 10 minutes of air path cleaning, connect the outlet of RAD7 to the inlet end of the drying cylinder to form a closed-loop circuit. This can continuously dry RAD7 without introducing fresh air.

　　If RAD7 has not been used for a period of time, or if the rubber hose connecting the air inlet and outlet has been disconnected, it will take longer for the air path to dry, at least 30 minutes or more. Once the drying process is completed, the air path cleaning during each measurement process only takes 10 minutes.
