Smart CO & CO₂ Monitoring

Two Important Gases. One Smart Monitor.

The PTH-281BW combines carbon monoxide and carbon dioxide monitoring in one compact device.

Instead of carrying separate monitors, you can easily check both gas levels together with temperature and humidity information.

Ideal for everyday monitoring in:

Home • RV • Camper • Cabin • Garage • Office

Real-Time Carbon Monoxide Monitoring

Carbon monoxide is colorless and difficult to notice without a detector.

The PTH-281BW continuously monitors surrounding CO concentration and displays the reading clearly on its color screen.

CO Detection Range

0–1000 ppm

Quickly check current CO levels and stay informed when environmental conditions change.

---

Monitor CO₂ Levels Too

Know When Indoor Air Needs Attention

High indoor CO₂ levels can indicate poor ventilation, especially in bedrooms, offices, RVs and other enclosed spaces.

The PTH-281BW monitors:

CO₂ Range

400–5000 ppm

Use real-time CO₂ readings to better understand ventilation conditions and know when fresh air may be needed.

5-in-1 Environmental Monitoring

More Than a Gas Detector

One compact monitor gives you access to multiple environmental readings:

CO

Carbon monoxide monitoring

CO₂

Carbon dioxide monitoring

Temperature

Track surrounding temperature

Humidity

Monitor relative humidity

Feels-Like Temperature

Understand how the surrounding environment actually feels

This makes PTH-281BW a practical everyday environmental monitor rather than a single-function gas detector.
