Corentium Pro is a light, portable and battery-operated Continuous Radon Monitor (CRM), designed for professional radon testing and home inspections.

Four highly accurate silicon photodiodes work in parallel for maximum reliabilityand performance, while the Bluetooth Smart® connectivity allows data to be wirelessly transferred to your smartphone or tablet.

With a battery lifetime of 1.5 years, you will never have to worry about finding an outlet anymore: the placement of the device is always optimal.

Weighing just 10.5 ounces (300 grams), Corentium Pro is the lightest approved CRM in the world, and a joy to work with.

There are no moving parts, cables, or adapters. The setup is quick and automatic, allowing you to focus on what matters most: serving your customers.

The Corentium Pro is tamper resistant, has additional sensors for temperaturepressure and humidity and safely stores all your measurements up to 5 years.

Corentium Pro samples indoor air through a passive diffusion chamber, using alpha spectrometry to precisely calculate the radon level. Radon is detected using silicon photodiodes to both count and measure the energy of alpha particles resulting from the decay chain of radon gas. The instrument is calibrated to reference instruments in accredited laboratories, and is C-NRPP certified.

The standard deviation from the exact radon level is less than

7% + 5 Bq/m3 after 24 hours (US: 7% + 0.12 pCi/L)

and less than

5% + 2 Bq/m3 after 7 days (US: 5% + 0.05 pCi/L)

The Corentium Report and Analyze (CRA) software, which comes with the Corentium Pro, allows the user to download all the data from the monitor and each sensor to a PC. The software functionalities are extensive, including the ability to generate custom graphics, custom professional reports, and convert all the data into a CSV file.

The iOS and Android applications provide responsive graphs that can be shown to a homeowner. Data is transferred from the Corentium Pro to your smartphone via Bluetooth.

Q: Kan jeg bruge dette som en husinspektør. Er NRPP certificeret?

Svar: Ja, Corentium Pro er fuldt certificeret af NRPP og kan gøre 48-timers målinger. Mange husinspektører og radon fagfolk på verdensplan allerede bruger det til at gøre officielle radon målinger.

Spørgsmål: Hvor hurtigt kan Corentium Pro display nøjagtige målinger? En fraflytter varer kun et par timer, det skal efterlades natten over?

Svar: I USA kan man tage en kortsigtet prøve, der varer mindst 48 timer. Selvom instrumentet er meget præcise i deres målinger, så svinger radon meget fra måned til måned. Derfor skæres målinger over flere måneder, der giver de bedste målinger.

Spørgsmål: Hvad er den anslåede batterilevetid instrumentets?

Svar: AA batterier holde i omkring 1,5 år i løbet kontinuerlig måling.

Q: Hvor nøjagtig er måleren?

Svar: Standardafvigelsen fra præcis radon niveauet er mindre end 7% efter 24 timer og mindre end 5% efter 7 dage. Nøjagtigheden kan forbedres ved at måle længere.
