FABISENSE PTH-9D / PTH-9DW Carbon Monoxide Monitor

See the Level. Hear the Alert. Stay Informed.

The FABISENSE PTH-9D / PTH-9DW Carbon Monoxide Monitor is designed for continuous indoor CO monitoring with a clear digital display and built-in audible alert.

It measures carbon monoxide from 0–500 ppm while also displaying temperature and humidity, helping you understand changing indoor conditions at a glance.

Choose the PTH-9D for simple standalone monitoring, or the PTH-9DW for added 2.4GHz Wi-Fi connectivity and Tuya Smart app support.

Real-Time Carbon Monoxide Monitoring

Carbon monoxide is invisible and difficult to detect without a dedicated monitor.

The PTH-9D series continuously measures CO concentration and displays the current level in real time.

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

The large numerical display makes CO levels easy to check from across the room.

Built-In Audible CO Alert

The built-in buzzer provides an audible warning when CO reaches the preset alarm level.

Default CO Alarm Value: 150 ppm

The CO alarm threshold can also be customized to better suit different monitoring environments.

Combined with the visual status indicator, the audible buzzer makes important changes easier to notice.

---

Large, Easy-to-Read Display

All key information is shown clearly on one screen.

View:

CO • Temperature • Humidity • Visual Status • Battery Level • Alarm Status

The large CO reading helps you quickly understand the current environment without navigating through complicated menus.

---

Visual CO Status Indicator

The visual status bar provides a quick reference for changing CO conditions.

Instead of relying only on numbers, you can see the current status more intuitively and recognize when CO levels begin to rise.

---

Temperature & Humidity Monitoring

In addition to carbon monoxide, the monitor also measures indoor temperature and relative humidity.

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

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

This gives you a broader view of the surrounding indoor environment from one compact device.
