AL-HB6300Intelligent Radon Meter (Electrostatic Collection Spectroscopy Method)

The AL-HB6300 series intelligent environmental radon measuring instrument is an electrostatic collection semiconductor sensor alpha spectrum analysis radon measuring instrument. By pumping the measured gas (air) into the electrostatic collection chamber, the first generation decay product RaA (218Po) of 222Rn is adsorbed onto the surface (cathode) of the semiconductor alpha ray sensor through a high-voltage electric field. Through energy spectrum analysis, the alpha particle count rate of RaA is measured, and the volume activity of 222Rn is quantitatively measured.

The instrument complies with:

GB 50325-2020 "Standard for Indoor Environmental Pollution Control of Civil Building Engineering" Pump suction static collection energy spectrum analysis method

Technical advantages

1. Exquisite, lightweight, and portable:

Dimensions (275x220x167) mm, weight 2.5kg

2. Advanced, accurate, and reliable:

The energy spectrum measurement of alpha particles with a short half-life of 222Rn (218Po half-life of 3 minutes) may effectively solve the interference of thorium gas in soil radon measurement. At the same time, due to the short half-life of the measured daughter, the detector can recover to a low background state in a relatively short time when measuring high activity (such as soil radon). Equipped with a built-in climate sensor, it can accurately measure the gas temperature, temperature, and atmospheric pressure inside the electrostatic chamber, used to indicate the status of the dryer, correct gas volume, and adjust temperature adsorption rate.

3. Intelligent and user-friendly:

The computer platform based on ARM processor and Android 4.4 operating system has powerful data processing capabilities, WIFI、 Rich data connection modes such as Bluetooth, USB (HOST/DEVICE mode), RJ45, RS232, etc., support users to update software.

4. Supporting facilities and complete functions:

Equipped with various professional accessories for measuring radon activity in soil, building materials, water, etc. Mature and reliable technical solutions, highly integrated platforms, and mature software environments make the device structure compact and the performance more reliable
