SPIRIT Radonlogger

from £1,188

SPIRIT radon logger incl. LoRaWAN network fee (3 years)

SPIRIT radon logger is a wireless detector with unique high sensitivity for simple and accurate radon measurements at workplaces and in homes. With the software, you can for example generate reports for follow-up radon measurements during working hours or for 2-day short-term measurements in homes.

You place the unit at the measuring site and log in to My Pages via our website. Once you have connected the radon logger to your account, the radon levels are displayed in real time. A graph visualizes the radon levels, temperature, humidity and air pressure for the measuring site. The average value and measurement uncertainty are calculated automatically between selected time intervals. Each unit is individually calibrated.

This is included in the package:

• Automatic connection to existing LoRaWAN network
• Free LoraWAN network fee for 3 years
• High-sensitivity radon detector with response time of less than 40 minutes
• Access to Radonova’s web platform with logger software
• Sensors for pressure, temperature, humidity and movement
• Battery power for 30 days
• Measures without connection, and sends measurement data as soon as it reconnects to a LoRaWAN network
• Calibrated for 1 year of use upon delivery. The extended package with service & calibration includes 2 more calibrations within 3 years

Common uses for SPIRIT radon logger are:

• To carry out accurate average measurements of the radon during working hours
• To calculate the estimated annual average value during working hours
• To obtain a valid 2-day short-term measurement in apartments or villas
• Log the radon levels in real time in connection with radon inspections or during follow-up of radon reduction measures

SPIRIT is not dependent on connection via Wi-Fi or Bluetooth. Instead, the public LoRaWAN network is used for communication with Radonova’s servers. It is not necessary to be connected to the network. The device still measures the radon levels, then automatically connects again as soon as the network is available.

As network coverage cannot be guaranteed in all locations, we always recommend supplementing with a gateway when purchasing your first SPIRIT device. Via a gateway, you can always reach the LoRaWAN network via a 4G subscription or with a network cable. To this gateway, all your devices can be connected to a radius of about 200 m in an indoor environment.
