Portable probe basis is a measuring chamber with a semiconductor photodetector. Radon enters the chamber by diffusion through the input filter on the bottom of probe. The probe measures in autonomous and time continuous way. It processes results in 2-minute intervals and from this counts short-term moving average of radon concentration (0,5 hour moving average – average of 15 2-minute process intervals from RaA(Po218)). It also counts long-term moving average of radon concentration (24 hours moving average from RaA(Po218)+RaC(Po214)). The probe saves time records of these radon concentration values RaA; RaA+RaC, including values of humidity and temperature within its internal memory (typically at an interval of 1 hour). Next saved value is time record of measuring energy spectrum (typically at an interval of 12 hours). The probe is random for location in measured place, but generally it is put on the bottom of the probe. Bottom of the probe cannot be covered. The probe can be switched on/off by switch. LEDs „STAT“ and „CHRG“ indicate current status of probe.
The resulting values can be downloaded continuously during measurement or at once at the end of measurement. Data from the radon probe can be downloaded to a PC directly via USB interface or wirelessly via antenna and Central Unit. Central Unit is not included with package and it is sold and delivered extra.
Measurement
- Continuous monitor of radon volume activity – radon concentration electronic measuring 20 – 100 000 Bq/m3
- Current radon concentrations – short-term (hourly average) and long-term (daily average)
- Measurement uncertainty – < 13% at 300 Bq/m3 per 1 hour; < 3% at 300 Bq/m3 per 24 hour
- Measuring algorithm – Calculation from RaA or from RaA +RaC impulses
- Accompanying measurements – temperature, humidity, energy spectrum
- Long-term records – results stored in internal memory for the period up to 208 days, export for spreadsheet
Data
- USB interface – data are downloaded directly via USB into PC
- Wireless interface – data are downloaded wirelessly via mobile Central Unit (supplied extra)
- Remote Access – Data from Central Unit can be downloaded over LAN or internet access.
- PC application – data managing, viewing, export and system configuration by PC application, Czech, English, German, Italian language
Advantages
- High Mobility – Portable device – easy equipment transfer between locations
- Nondestructive Installation – Internal accumulator with battery life more than 1 year without charging
- Autonomous Measuring – Each probe separately measures and stores data into internal memory
- Data Download Options – Continuously or one-time after measurement end
- Wireless Network – Up to 16 elements with one central unit
- Wireless Range – Can be increased by repeaters
- Technical Support – Extensive services directly from manufacturer
