CO₂ • PM2.5 • PM10 • HCHO • TVOC • C6H6 • Temperature • Humidity
No need to switch between several different monitors.

Clear All-in-One Display
The large color screen organizes multiple readings into one easy-to-view interface.
Quickly check:
- CO₂ concentration
- PM2.5 and PM10
- HCHO
- TVOC
- C6H6
- Temperature
- Humidity
- AQI
- Time and calendar
One glance gives you a broader picture of your indoor environment.

Real-Time CO₂ Monitoring
Monitor indoor carbon dioxide levels from:
400–5000 ppm
Real-time readings make it easier to notice when CO₂ levels begin to rise, especially in enclosed or occupied rooms.
Useful for:
Bedroom • Office • Meeting Room • Classroom • Living Room

PM2.5 & PM10 Particle Monitoring
Track two important particulate-matter measurements:
PM2.5: 0–1000 μg/m³
PM10: 0–1000 μg/m³
Monitor changing particle levels caused by everyday indoor activities and surrounding environmental conditions.

Monitor Multiple Indoor Pollutants
Beyond CO₂ and particulate matter, the PTH-9B series also monitors:
HCHO: 0–2 mg/m³
TVOC: 0–5 mg/m³
C6H6: 0–3 mg/m³
This makes it suitable for users who want a more complete view of indoor air conditions rather than only monitoring one parameter.

Temperature & Humidity at a Glance
Built-in temperature and humidity monitoring helps you understand overall indoor comfort together with air-quality conditions.
Temperature: -10°C to 40°C
Humidity: 20%–80% RH
Air quality and comfort information are displayed together on the same screen.
