## Summary description

TechnoLine WL1025 Black is a battery-powered CO2 monitor with built-in indoor and outdoor thermometers and trend display for temperature. It measures carbon dioxide (CO2) levels and shows thermometer trends to help monitor air quality and temperature variations in homes, offices or classrooms. Compact design for wall or desktop use.

## Long description

TechnoLine WL1025 Black is a battery-powered CO2 monitor with integrated indoor and outdoor thermometers and a trend display for temperature. Its compact enclosure and dual mounting options allow placement on a desktop or fixed installation on a wall. The device continuously measures ambient carbon dioxide concentration and displays current indoor and outdoor temperatures, helping to track air quality and temperature changes in homes, offices and classrooms.
Advantages
The WL1025 provides continuous CO2 monitoring with a clear numeric display and a temperature trend indicator that helps identify gradual changes. Battery operation removes the need for nearby mains power and enables flexible placement. The compact design combines CO2 measurement and both indoor and outdoor temperature sensing in a single unit, reducing the number of separate devices needed to monitor indoor climate.
Suitable for
Monitoring indoor air quality in living rooms, bedrooms and home offices
Use in offices, meeting rooms and classrooms to assess ventilation needs
Placement in small commercial spaces or reception areas where portable monitoring is useful
Portable or temporary monitoring when mains power is unavailable
When it may not be suitable
The WL1025 is intended for general indoor air quality and temperature monitoring and is not certified for medical or industrial hazardous-gas detection. It uses battery power, so continuous long-term operation requires periodic battery replacement. For precise environmental control in specialized laboratories or industrial sites, devices with professional calibration or wired power may be more appropriate.
Key specifications
Measurements: carbon dioxide (CO2) concentration; indoor and outdoor temperature
Power source: battery operation for flexible placement
Display: numeric CO2 readout and temperature trend indicator
Mounting: desktop placement or wall mounting
Design: compact housing intended for home and office environments
How to use
Install batteries according to the user manual, choose either a desktop location or mount the unit on a wall at breathing height for representative indoor readings. If an outdoor probe or external temperature sensor is included, place it outdoors sheltered from direct sun and precipitation. Allow the device to stabilise for several minutes after placement to obtain accurate CO2 and temperature readings. Use the trend display to observe gradual temperature changes and refer to the numeric CO2 value to decide on ventilation actions.
What to consider before purchase
Intended use: general indoor air quality monitoring, not for medical or hazardous industrial gas detection
Power: battery operation — factor in battery life and accessibility for replacement
Placement: plan for desktop or wall mounting and location away from direct heat sources or drafts for accurate readings
Accuracy needs: check whether the provided measurement accuracy and sensors meet your monitoring requirements
Usage recommendations
Position the WL1025 at typical breathing level in occupied rooms, avoid placing it next to heating vents or open windows, and ventilate spaces based on measured CO2 values and occupancy. Replace batteries as recommended to ensure continuous monitoring and allow the unit time to stabilise after movement or battery replacement for reliable readings.
