Temtop Portable CO2 Monitor Indoor Air Quality Meter — NDIR Sensor, CO2/Temp/Humidity, Compact Battery-Powered

The Temtop Portable CO2 Monitor is a compact, battery-powered indoor air-quality meter that continuously displays CO₂ concentration, temperature, and humidity for homes, offices, and classrooms.

Keep tabs on the air where you live, work, and learn with a single, easy-to-read device. This Temtop monitor uses an advanced NDIR sensor to measure CO₂ from 400 to 5000 ppm, reports temperature from -10°C to 60°C (14°F–140°F), and tracks relative humidity between 0–99% RH. Its compact housing, clear display, and configurable alerts make it practical for monitoring ventilation and comfort across rooms, small offices, classrooms, and grow tents.

How accurate and responsive is the CO₂ measurement?

The Temtop monitor uses a Swiss-engineered NDIR sensor with high precision and fast refresh. Accuracy is ±40 ppm plus 5% of the reading in the typical 400–2500 ppm range, and the display updates every 5 seconds to show small fluctuations.

• Swiss-engineered NDIR sensing for stable readings.
• 1 ppm display resolution for clear trend spotting.
• 5-second refresh rate to capture rapid changes in air.
• Reliable accuracy within the most relevant indoor range.

What else does the device measure and how is that useful?

Besides CO₂, the unit measures temperature and relative humidity so you can assess overall indoor comfort and environmental conditions in one glance. These three parameters help you evaluate ventilation, occupant comfort, and conditions for plants or equipment.

• Temperature range -10°C to 60°C (14°F–140°F) for varied environments.
• Humidity 0–99% RH to monitor dryness or dampness trends.
• Combined readings displayed together to simplify interpretation.
• Useful for classrooms, offices, nurseries, and grow spaces.

How portable and easy to use is the monitor for everyday settings?

The monitor’s slim profile and long battery life make it simple to move between rooms or mount on a wall. It includes a USB cable, mounting bracket, and a full standby time of up to 70 days using the new photoacoustic sensor technology, allowing prolonged monitoring without frequent charging.

• Compact, lightweight design for easy relocation.
• Mounting bracket for wall or vertical surface placement.
• USB powered with included cable for continuous operation.
• Up to 70 days standby—ideal for occasional or continuous use.

Can I customize alerts and avoid disturbance during sleep or meetings?

Yes — the Temtop monitor offers configurable alerts and display settings so you can silence audio alarms or turn off display illumination when you need quiet. That makes it convenient for bedrooms, conference rooms, or shared spaces where disturbance must be minimized.

• Disable audio alerts for quiet environments.
• Turn off display illumination for undisturbed sleep.
• Smart alert thresholds to notify when CO₂ rises beyond chosen levels.
• Clear on-device readings so you don’t need an app to check data.

Who this product is for: Ideal for homeowners, teachers, small-business owners, indoor gardeners, and building managers who want a portable, no-fuss tool to monitor ventilation and indoor comfort. If you need a reliable meter to check CO₂ levels alongside temperature and humidity without complex setup, this Temtop monitor provides accurate measurements, easy mounting, configurable alerts, and long battery life to suit everyday room-by-room air-quality checks.
