Ajax 52272.135.BL1 LifeQuality Jeweller Wireless Air Quality Monitor, Temperature, Humidity & CO₂, 2 × CR123A Battery
About this product
The Ajax LifeQuality Jeweller (52272.135.BL1) is a wireless temperature, humidity and CO₂ monitor in black for Ajax systems, connecting to a hub or range extender over Jeweller. Designed only for indoor installation, it tracks air quality, lights its LED when air quality changes critically and shows charts of temperature, humidity and carbon dioxide concentration in the Ajax apps.
Key features
- CO₂ measurement range from 400 to 10,000 ppm
- Temperature measurement from 0 °C to +50 °C with ±0.2 °C accuracy
- Humidity measurement from 0% to 100% with ±1.8% accuracy
- Colour LED indication: green for normal air, yellow for slightly polluted, red for polluted and purple for critically polluted air
- Jeweller radio range of up to 1,700 m between the detector and a hub/range extender in an open space
- Automatic CO₂ sensor calibration once every 1–14 days
- Backup memory of up to 3 days if communication with the hub is lost
- Powered by 2 × CR123A batteries, pre-installed
Frequently asked questions
What does the LifeQuality Jeweller measure?
Temperature from 0 °C to +50 °C, humidity from 0% to 100% and CO₂ concentration from 400 to 10,000 ppm.
What powers it and how long do the batteries last?
It runs on 2 × CR123A batteries, which come pre-installed, for up to 3 years of autonomous operation, or 2.5 years if LED indication and accelerometer are enabled.
Can it be used outdoors?
No. The device is designed only for indoor installation at any height, and it can also be placed on a table or shelf.
What is the wireless range to the hub?
Up to 1,700 m between the detector and a hub/range extender in an open space, over Jeweller.
Does it need calibrating?
The CO₂ sensor calibrates automatically once every 1–14 days. Manual calibration is run in the Ajax apps and suits unventilated rooms.
What happens to readings if it loses connection with the hub?
It stores all measured values in backup memory for up to 3 days and sends them to the Ajax app once the connection is restored.
