It's not always sunshine and ice-cream at campsites. Dampness and rain make an appearance.

Let’s get this right out of the way: You can use the same moisture meters for your home for caravans and motorhomes. You don’t need a specific one for vehicles.

But, the difference is that not all damp meters can read moisture in fabric. Since you’ll be sticking the pins into fabric, you’ll get more accurate results by using a detector designed for caravans.

Damp can ruin the materials and fabric used for upholstery, so it’s something you want to avoid before the problems get worse.

You don’t want the onset of black mould in areas you can’t see. It’s a massive health hazard and can cause breathing difficulties for years if undetected.

A damp detector is an excellent tool to help you with detecting damp early on so you can treat it before it’s hopeless. This will save you a lot of stress, money and time. Now, you can proceed with this in one of two ways:

  1. Take your caravan to a service centre for a checkup.
  2. Or get a damp detector of your own and check your caravan on a regular basis, free of charge. The key is regular checkups and practising preventive measures.

Motorhome damp detectors play a crucial role here as they can warn you beforehand. If it is important for you to maintain a healthy environment, you may consider the second option.

To help you with the right purchase, we’ve selected some of the best products in the market.

FAQ and Buying Guide

It varies from model to model, but generally, here’s how to use one:

  1. Power on, and set the device to read what kind of surface you are measuring
  2. Once you have chosen a measurement mode, place the pins on the surface for a few seconds
  3. You will find the result displayed on the screen

If it’s on the surface, you can scrub most of it with warm water, a drop of mould spray. Or, scrub it off with a damp cloth using a mix of half-vinegar, half warm-water.

Never use bleach when cleaning off mould.

Please remember to wear some durable gloves, goggles and a protective mask.

If you’re in a damp space and there’s little ventilation, it’s bad for the caravan and bad for your personal health. Don’t let mould settle. The best way to beat the onset of damp is to keep your caravan well ventilated.

What is a Damp Detector?

They’re the size and shape of a small remote with two pin-sensors that help detect the moisture. An electric charge flows between the two pins when they come in contact with the surface you are testing.

Moisture can accumulate for several reasons including high humidity, water intrusion, condensation. Knowing the moisture level can help you decide what your next step should be.

What do the Results Imply?

If you’re testing your caravan’s health, you’ll need to have a clear understanding of what the results imply, expressed in percentage form. Keep in mind that the result indicates the moisture level of a particular area and not the whole caravan.

That is to say, the results are location-specific and may vary within the caravan. This is how you should interpret the results:

● 0 to 15% would mean that the surface is dry and without any damp

● 15 to 20% would imply that the location is at risk of damping. You might want to check on it again in a month or two

● 20 to 25% means that this particular area needs further investigation

● 25 to 30% implies that there might be water ingress present in the area

● And anything above 30% needs your special attention and immediate action

How to Choose the Best Damp Detector for Caravans

Before diving into reviews, let us look at the criteria of a good damp detector:

Pins vs. Pinless: While shopping for damp detectors, you will find two kinds: with pins and without pins. Generally, the pin damp detectors tend to be more versatile and functional. While pin meters use electric current, pinless meters work with an electromagnetic field.

Pin Length: The moisture level depth of a board is about one quarter to one-fifth of the board. Considering the depth of a regular board, it is ideal if you get a damp detector with pins of at least 0.3 inches length.

Display Type: Need to pay attention to the display type and size of the damp detector. Some options available in the market include LED, LCD, Analog, and Digital LED

Price: The price of damp detectors can range from as low as $30 to over $250. It is up to you to decide your budget and find the best damp detector at that price point. We hope our review will help.
