Equipped with high sensitivity detection sensors, this radon monitor supports accurate real time radon gas concentration testing and provides two core data analysis modes including long term average detection and short term average detection. It can record and display stable long term radon average values and real time short term average values, allowing users to fully grasp the indoor radon gas content changes in different time cycles, effectively helping judge indoor air safety status.

The detector supports dual professional measurement unit switching, covering the two most internationally mainstream radon concentration units pCi/L and Bq/m³. Users can freely switch the display unit according to regional testing standards, detection habits and different industry detection requirements, realizing global universal detection and data reading.

Built with professional manual calibration function, this radon gas tester allows users to manually calibrate the detection data regularly to ensure long term detection accuracy, avoid data deviation caused by long term use, environmental changes or sensor aging, and maintain stable and reliable testing performance all the time.

Lightweight and portable in overall structure, the black integrated body is durable, scratch resistant and easy to carry. Users can hold it by hand for mobile spot detection in different rooms, or place it stably on desks, cabinets and flat surfaces for 24 hour continuous indoor radon monitoring, realizing dual scene application of portable inspection and fixed continuous monitoring.

This radon gas detector has passed strict CE and RoHS official certification, fully complying with European standard safety regulations and environmental protection requirements. The product features safe circuit design, stable working performance, no radiation, no pollution, low power consumption and high safety level, which can be safely used for long term indoor family environment monitoring, office building air detection, new house post renovation air quality inspection, real estate house inspection and field environmental safety testing.

Suitable for a wide range of application scenarios including family residences, bedrooms, living rooms, office spaces, commercial buildings, newly renovated houses, real estate house pre purchase inspection and indoor environmental field detection. It is an essential professional household air quality testing tool to prevent excessive radon gas and protect family and staff respiratory health and indoor living safety.

FAQ

Q1:What is radon gas?
Answer:
Radon gas is a radioactive noble gas primarily originating from the decay of uranium in soil and rock formations. It typically infiltrates buildings through ground penetration. With a higher density than air, radon tends to accumulate in lower areas,particularly near floor surfaces.

Q2: Does the radon concentration measured at floor level by the detector equal airborne radon concentration?
Answer:
No. Radon concentrations near floor surfaces may exceed those at elevated positions due to radon's higher density, which causes gravitational settling. Measurements taken directly on the floor reflect source-proximal concentrations, whereas central or elevated areas of the room may exhibit lower values.

Q3: How long does the device require to display accurate readings?
Answer:
Measurement duration varies by operational mode:

Rapid Mode: Delivers stabilized readings within 48 hours of initial activation.

Long-Term Mode: Requires continuous monitoring for at least 7 days to establish spatial average concentrations.

Q4: Where should the detector be positioned?
Answer:

Floor-level measurement: Place the device horizontally on the floor.
Wall-proximate measurement: Mount the device vertically on the wall.

Breathing-zone measurement: Position the device approximately 1 meter above floor level.
Note: Avoid areas with airflow disturbances such as air conditioner vents or radiators.

Q5: Can this device test radon in water?
Answer:
This instrument is exclusively designed for air medium analysis. For aqueous radon testing,
use dedicated hydro-radon testing equipment to prevent sensor damage.

Q6: At what concentration threshold should corrective action be taken?
Answer:
Per WHO safety guidelines:
2.70 pCi/L (100 Bq/m³): Implement mitigation measures (e.g., enhanced ventilation, crack sealing).
8.10 pCi/L (300 Bq/m³) : Engage certified professionals for structural remediation.
 

Q7: Why do radon readings exhibit sudden fluctuations?
Answer:
As a gaseous radioactive element, radon concentrations are dynamically influenced by:
Atmospheric pressure changes
Temperature/humidity variations
Ventilation rate shifts (e.g., door/window operation)
Intermittent soil gas infiltration

Resolution:
Maintain continuous monitoring for ≥48 hours
Conduct critical measurements only after maintaining closed conditions for 12 hours

Q8: When should manual calibration be performed?
Answer:
Initiate calibration under these conditions:
Following significant environmental condition changes
Upon detection of abnormal measurement deviations
