FABISENSE PTH-9R 4-in-1 CO & CO₂ Detector

Two Gases. One Compact Monitor.

Monitor carbon monoxide, carbon dioxide, temperature and humidity with one compact device.

The FABISENSE PTH-9R provides real-time CO and CO₂ readings, adjustable alarm settings, temperature and humidity monitoring, and a built-in rechargeable battery for flexible indoor use.

4-in-1 Indoor Monitoring

Keep important indoor air information visible at a glance.

• Carbon Monoxide (CO)
• Carbon Dioxide (CO₂)
• Temperature
• Humidity

One device gives you a clearer view of changing indoor conditions.

Real-Time Carbon Monoxide Monitoring

The PTH-9R continuously monitors carbon monoxide levels from 0–500 ppm.

CO Range: 0–500 ppm
CO Accuracy: ±10%
CO Resolution: 1 ppm
CO Response Time: <60 seconds

The large digital display makes current CO readings easy to check.

CO₂ Monitoring Up to 5000 ppm

The PTH-9R also monitors indoor carbon dioxide levels to help you better understand changing air conditions in enclosed spaces.

CO₂ Range: 400–5000 ppm
CO₂ Accuracy: ±(50 ppm + 5%)
CO₂ Resolution: 1 ppm

Suitable for bedrooms, living rooms, offices, cabins, RVs and other indoor environments.

Adjustable CO & CO₂ Alarms

Customize the alarm thresholds according to your monitoring needs.

Default CO Alarm: 150 ppm
Default CO₂ Alarm: 1500 ppm

Both alarm values can be adjusted.

When the monitored concentration reaches the set threshold, the built-in buzzer provides an audible alert.

Clear Dual-Gas Display

See key information directly on one screen.

The display shows:

• CO Concentration
• CO₂ Concentration
• Temperature
• Humidity
• Battery Status
• Alarm Status

Clear numerical readings and visual indicators make daily monitoring simple.

Temperature & Humidity Monitoring

The PTH-9R also tracks surrounding temperature and relative humidity.

Temperature Range: 0°C–50°C / 32°F–122°F
Temperature Accuracy: ±1.5°C / ±2.7°F
Temperature Resolution: 1°C / 1°F

Humidity Range: 20%–80% RH
Humidity Accuracy: ±5%
Humidity Resolution: 1%

Rechargeable for Flexible Placement

A built-in 2000mAh rechargeable Li-Po battery allows you to place the monitor where you need it.

Battery: 2000mAh
Charging: USB Type-C
Input: 5V ⎓ 1A
Low Battery Alert: Yes

Easy to recharge and convenient to move between indoor spaces.
