Water spots on the ceiling. Punky floors. Distorted walls. A musty smell.
These are the immediate signs of a moisture issue in a residential home. But they’re also a good indicator of a dampness problem in a caravan, RV or mobile home.
For touring vehicles such as caravans (RVs), a dampness issue can carry high repair costs. What’s more, dampness presents potential health & safety hazards -- where there’s moisture, there may be dangerous molds.
Preventing dampness in a caravan is about being proactive. A caravan damp meter (moisture meter) is your #1 tool in making sure dampness doesn’t stop you from enjoying the vehicle for years to come.
Where, When, & How to Use a Damp Meter in a Caravan
A home away from home, caravans are susceptible to the same moisture issues as a house. Inspecting a caravan for dampness isn’t unlike a home moisture inspection. A thorough survey involves:
Checking the right spots
Inspecting at the right times
Using the right damp testing equipment
1. Caravan Damp Testers: Where to Check
Just like a house, there are plenty of places where moisture can cause issues in a recreational or touring vehicle. A moisture inspection should always include the obvious places to test, such as:
Around windows, doors, and skylights
Near plumbed fixtures
There are not-so-obvious spots to check, too:
Inside cabinets and storage spaces
2. When to Inspect Caravans for Dampness
While there’s no set time for how frequently you should test a caravan for moisture, there are key points during an RV’s life when a moisture survey is recommended:
Before use: There’s nothing worse than traveling with a caravan far from home, only to discover a moisture-related issue, such as a deteriorated section of floor or wall.
After use: Caravans are meant for outdoor use. Exposure to the elements, or even minor damage while traveling, may provide an opening for dampness to make its way inside.
In between uses: It may be weeks or even months before you hit the road again. That’s more than enough time for a small moisture issue to become a much larger one.
3. How to Inspect Caravans for Dampness: What to Use
When inspecting a touring vehicle for dampness, having the right tools -- primarily damp meters and a hygrometer-- are critical.
Pin-type damp meters determine actual moisture content in a material. Using electrodes, a pin-type meter gauges moisture by measuring electrical residents between its pins.
Pinless moisture meters confirm dampness within a material. These noninvasive meters use radio frequencies to assess average moisture content within their depth of measurement. A pinless moisture meter is ideal for taking readings in hard-to-reach places, such as behind walls or underneath floor panels.
Hygrometers measure relative humidity (RH) within a space. A good starting point for a dampness survey, if a hygrometer determines high humidity in a caravan, a dampness issue may be the cause.
What’s the Best Damp Meter for Caravans?
When taking damp meter readings in caravans, there’s only one damp meter choice: all of the above.
Pin-type and pinless moisture meters go hand-in-hand. One lets you seek out and confirm the presence of dampness in a caravan, while the other tells you the extent of moisture within its materials. And hygrometers are a great tool for detecting condensation.
Caravan Damp Meters for Routine Maintenance & Inspections
Causing damage that can go unnoticed for long periods of time, dampness is one of a caravan’s worst enemies. By using a caravan damp meter for regular inspections, you’ll have the upper hand on preventing dampness issues from ruining the vehicle.
