AT-A-GLANCE COMPARISON
Why Most CO Detectors Cannot Match Fabisense
Most standard CO detectors only alert you when carbon monoxide reaches a dangerous level, giving you little visibility into what is happening before the alarm sounds.
Fabisense PTH-24D was designed differently. It combines real-time CO readings with temperature and humidity monitoring, giving you a clearer picture of your indoor environment day and night.
Powered by a high-precision electrochemical CO sensor, it continuously keeps watch while the easy-to-read digital display puts important information right in front of you.
More than an alarm. A clearer view of the air around you.

FIREFIGHTER PERSPECTIVE
“After 12 Years as a Firefighter, Carbon Monoxide Is One Risk I Never Take Lightly.”
“Over the past 12 years, I have seen how dangerous carbon monoxide can be, especially because you cannot see it, smell it, or always recognize the warning signs before it becomes a serious problem.
That is why I like the simplicity of the PTH-24D. It continuously monitors carbon monoxide, temperature, and humidity in one compact plug-in device, giving you clear real-time readings at a glance.
For homes and especially RVs, where families may sleep near fuel-burning appliances in smaller enclosed spaces, continuous CO monitoring is something I consider extremely important. I also appreciate being able to check the temperature and humidity at the same time, which makes it easier to understand the overall indoor environment.
Simply plug it into a wall outlet and let it keep watch day and night.
Whether I were protecting my family at home or spending the night on the road in an RV, the PTH-24D is the kind of monitor I would want nearby.”

Fabisense Detector warns you first
It doesn’t wait until the air is dangerous. You see the number rise from zero — and act before a late alarm becomes the first sign of trouble.
THE PART NOBODY TELLS YOU
Your alarm is built to stay silent until it’s almost too late.
Carbon monoxide harms the body long before a standard alarm reacts — and it can legally wait hours to sound. That’s why seeing the live number matters.

THE SILENT KILLER
You can’t see it. You can’t smell it.
And it doesn’t hurt.
CO leaks from furnaces, water heaters and stoves — and a dead sensor keeps glowing green anyway.

Then the sensor dies — silently
A threat you’ll never sense
No color, no smell, no warning — and a standard alarm can stay silent until it’s already dangerous.

FREQUENTLY ASKED QUESTIONS
Everything You Need to Know About PTH-24D
Can I use PTH-24D outside my home as well?
Yes. PTH-24D is ideal for houses, apartments, cabins, vacation rentals, RVs, campers, and other enclosed living spaces where carbon monoxide may become a concern. Its compact plug-in design makes it easy to use wherever a suitable power outlet is available.
At what CO level does PTH-24D alert?
PTH-24D continuously monitors carbon monoxide and uses four visual and audible states based on the measured concentration:
- 0-50 ppm - Green breathing light: The emerald-green breathing light flashes, the screen shows a green status icon, and the buzzer remains silent.
- 51-100 ppm - Orange breathing light: The orange breathing light flashes, the screen shows a yellow warning icon, and the audible alarm sounds.
- 101-150 ppm - Orange flashing light: The orange light flashes, the screen shows an orange warning icon, and the audible alarm sounds.
- More than 150 ppm - Red warning: The red light flashes, a red warning appears on the screen, and the audible alarm sounds. The high-level warning cannot be dismissed while the reading remains above this range.
Never ignore an alarm. Move to fresh air and follow the product manual and applicable local emergency guidance.
Does PTH-24D work during power outages?
PTH-24D is a plug-in powered monitor and requires continuous external power to operate. If power is interrupted, monitoring will pause until electricity is restored.
How long does the sensor last?
PTH-24D is built for long-term everyday use with a 10-year sensor service life. When the sensor reaches the end of its lifespan, the device provides an automatic end-of-life reminder, so there is no need to remember the replacement date yourself.
10-Year Sensor Life. Automatic End-of-Life Reminder.
Will everyday activities cause false alarms?
PTH-24D is designed for reliable everyday monitoring. However, strong chemical vapors, concentrated alcohol, solvents, ammonia, and certain household products may temporarily affect sensor readings.
For best performance, keep the monitor away from strong chemical fumes and maintain normal ventilation during cooking and cleaning.
Where should I place PTH-24D inside my home?
Place PTH-24D in an area where you want continuous CO monitoring, such as near sleeping areas, hallways, living spaces, furnaces, water heaters, or other areas near fuel-burning appliances.
Keep the air vents unobstructed and avoid placing the device near water, excessive dust, direct sunlight, or extreme heat. Always follow the user manual and local safety requirements when selecting a location.
How does PTH-24D alert me?
PTH-24D combines color-coded indicator lights, a clear digital display, and an audible alarm to make changing CO conditions easy to recognize.
You can see real-time CO readings directly on the screen, while elevated levels trigger visual and audible warnings to help get your attention quickly, including while you are sleeping.
Is PTH-24D better than a standard CO detector?
Many traditional CO detectors primarily provide an audible alarm when carbon monoxide reaches an alarm condition.
PTH-24D gives you more visibility by combining real-time CO readings, temperature, and humidity monitoring in one compact 3-in-1 device.
Instead of only hearing an alarm, you can check your indoor environment at any time and see what is happening at a glance.
Real-Time CO. Temperature. Humidity. One Simple Plug-In Monitor.

What Customers Say About PTH-24D
L
We use gas heating in winter, so having a dedicated plug-in monitor near the bedrooms makes me feel much more informed. The 3-in-1 layout keeps the information simple and useful, with no need to juggle separate devices around the room. I would gladly use another one in a second part of the house because the format is so convenient.
H
During cold weather we run the heat for long stretches, so seeing CO, temperature, and humidity together is reassuring. It does one job clearly: it keeps the three key readings visible so the whole family can check them at a glance. I would gladly use another one in a second part of the house because the format is so convenient.
M
Our furnace room is close to the main living space, and this gives us a convenient way to check CO plus temperature and humidity. I appreciate the continuous monitoring because conditions can change while we are cooking, heating the house, or sleeping. This is the kind of home-safety product I appreciate most: simple to use, always visible, and easy to understand.
G
I wanted something simple for our upstairs living area, especially during the months when the windows stay closed most of the day. Having temperature and humidity next to the CO reading also helps me understand why a room feels stuffy, dry, or uncomfortable. For anyone who wants a no-fuss way to watch CO and basic room climate, this is a very useful device.
L
We recently renovated and started paying more attention to indoor conditions, especially when doors and windows are closed. The display is easy to read from nearby, so I can check the room conditions during the day without interrupting what I am doing. It gives me the information I wanted without taking up counter space or requiring a complicated installation.
N
We have a busy family household, so I appreciate products that work quietly in the background and are easy for everyone to understand. The plug-in format keeps it in one consistent location, which is exactly what I wanted for everyday home monitoring. For our family, it is a practical little layer of awareness that we now prefer having on every day.
A
I placed the PTH-24D in our basement family room, where air conditions can feel very different from the rest of the house. Setup was exactly what I hoped for: plug it into the outlet, let it run, and check the readings whenever needed. It is compact, uncomplicated, and has earned a permanent spot in our home.

C
We were looking for a straightforward monitor for our parents home that would not require a lot of setup or app menus. It has become part of my normal routine to glance at the CO level and room climate when I walk past it. After a few days, checking it became second nature, and I would miss having those readings available now.
