No internal battery
Powered directly from the vehicle socket, so there is no separate charging routine.
Built for vehicle cabins
See CO₂ inside your car — in real time.
EVO-CO2V plugs directly into a 12V/24V vehicle socket, samples CO₂ every 10 seconds and gives an audible alert above 1400 ppm.

Why EVO-CO2V
Designed around the way a car is actually used.
A fixed power point, fast sampling and a clear display make it practical for everyday vehicle use.
⏱
10-second sampling
Frequent readings help you follow changing CO₂ conditions inside the cabin.
🔔
Audible high-CO₂ alert
A beep sounds above 1400 ppm as a reminder to improve ventilation when safe.
Vehicle-ready mounting
Plug it in. Set the angle. Keep the reading in view.
The display head can be adjusted for different console layouts and accessory-socket positions.
- ✓ No loose charging cable across the dashboard.
- ✓ A consistent mounting point for everyday monitoring.
- ✓ Rotatable screen for easier viewing.
Clear information at a glance
CO₂ concentration and vehicle voltage on one color screen.
The display keeps the two readings visible together so you can check cabin CO₂ and the vehicle supply voltage quickly.
- ✓ Large CO₂ ppm value.
- ✓ Vehicle voltage display.
- ✓ Color status presentation for faster reading.
Start-up
Allow the NDIR sensor to stabilize after power-on.
After plugging in the meter, let the warm-up sequence complete before relying on the displayed cabin CO₂ value.
- 1 Plug into a compatible 12V/24V socket.
- 2 Let the sensor complete its warm-up.
- 3 Monitor the live cabin reading while driving.
NDIR CO₂ sensing
Measures carbon dioxide using infrared absorption.
NDIR sensing passes infrared light through a gas chamber. CO₂ absorbs specific infrared wavelengths, allowing the sensor to estimate concentration.
Important:
EVO-CO2V measures carbon dioxide (CO₂).
It does not measure carbon monoxide (CO)
and is not a replacement for a certified CO alarm.
Everyday vehicle use
Useful whenever people spend time in a closed cabin.
Keep cabin CO₂ visible during normal driving and longer trips.
Daily commuting
Watch how CO₂ changes during routine city and highway driving.
Road trips
Keep the reading visible during longer periods with windows closed.
Family vehicles
More occupants can change cabin air conditions faster.
12V / 24V vehicles
Designed for compatible vehicle accessory sockets.

FAQ
Before you plug it in.
Does EVO-CO2V measure carbon monoxide (CO)?
No. EVO-CO2V measures carbon dioxide (CO₂). It is not a carbon monoxide detector.
Does it contain a rechargeable battery?
No. It is powered directly from a compatible 12V/24V vehicle socket.
How often does it sample CO₂?
The device samples CO₂ every 10 seconds.
When does the audible alert sound?
The high-CO₂ beep alert is triggered above 1400 ppm.
Can I adjust the viewing angle?
Yes. The display head can be rotated to suit different vehicle console positions.
Make cabin CO₂ visible.
Plug in EVO-CO2V, let the sensor stabilize and keep the current value in view.
Vehicle Air-Quality Definitions
CO₂ and CO are different gases
EVO-CO2V measures carbon dioxide using NDIR sensing. It does not detect carbon monoxide and is not a replacement for a certified CO alarm. Review CO₂, CO, NDIR, ventilation and recirculation terminology in the glossary.
