PTH-28B Outdoor Multi-Gas & Air Quality Monitor
Know Your Air. Stay Ready Outdoors.
Whether you're camping, traveling by RV, cooking outdoors, relaxing around a fire, or spending time in an enclosed shelter, air conditions can change quickly.
The PTH-28B Outdoor Environmental Guardian combines multi-gas monitoring, environmental sensing, visual alerts, and smart app connectivity in one compact portable device—helping you stay informed about the environment around you.
All-in-One Environmental Monitoring
One compact device gives you access to multiple environmental readings:
-
Carbon Monoxide (CO) Monitoring
-
Carbon Dioxide (CO₂) Monitoring
-
UV Index (UVI)
-
Temperature
-
Humidity
-
Perceived Temperature / Heat Index
-
Audible & Visual Alerts
-
Emergency Flashlight
-
Bluetooth App Connectivity
Instead of carrying multiple individual meters, the PTH-28B puts essential environmental information right on one easy-to-read display.
Carbon Monoxide Monitoring
Carbon monoxide is colorless and odorless, making it difficult to notice without a dedicated sensor.
The PTH-28B continuously displays the current CO concentration in ppm and provides clear visual warnings when readings reach configured alert levels.
CO Reference Levels
| Status | CO Concentration |
|---|---|
| Safety | 0–49 ppm |
| Warning | 50–99 ppm |
| Danger | 100 ppm+ |
When elevated CO is detected, the display makes the warning easy to recognize at a glance.
Especially useful around: camping equipment, RVs, cabins, outdoor cooking areas, generators, heaters, fire pits, and other combustion-related environments.
Carbon Dioxide Monitoring
Poor ventilation can allow carbon dioxide levels to increase, particularly in tents, RVs, cabins, vehicles, shelters, and other enclosed or semi-enclosed spaces.
The PTH-28B displays real-time CO₂ concentration in ppm, helping you recognize when ventilation may be needed.
CO₂ Reference Levels
| Status | CO₂ Concentration |
|---|---|
| Safety | 400–1000 ppm |
| Warning | 1001–2000 ppm |
| Danger | 2000 ppm+ |
See the current reading directly on the device and respond quickly when air conditions change.
Clear 1.8" Touchscreen Display
No complicated menus. No guessing what the numbers mean.
The 1.8-inch LCD touchscreen brings key readings together on one interface, including CO, CO₂, temperature, humidity and UV information.
Large numerical readings and color-coded warning indicators make important information easier to understand—even when you're outdoors.
Audible & Visual Alerts
A monitor is only useful when you notice the warning.
The PTH-28B combines on-screen warning indicators with audible alerts, helping draw attention to elevated readings even when you're focused on other activities.
The interface provides clear status information so you can quickly determine when conditions require attention.
UV Index Monitoring
Air quality isn't the only environmental factor that matters outdoors.
The integrated UV Index monitor gives you additional information about current UV conditions, making the PTH-28B a practical companion for:
-
Camping
-
Hiking
-
Fishing
-
Beach trips
-
Outdoor work
-
Road trips
-
RV travel
-
Family outdoor activities
Check UV conditions directly from the same device you use to monitor your surrounding air.
