“Where does moisture come from?” – determining air temperature and air humidity

How does moisture actually emerge in the components of a house – and in doing so pave the way for mould infestations? The so-called ‘dew point’ provides an answer to this question. This is the temperature at which the air releases its contained water as condensate. Therefore, the precise measurement of air temperature and humidity as well as the exact determination of the dew point temperature are at the heart  of building diagnostics – as well as for the accompanying measuring devices: the professional thermohygrometers from Trotec.

New moisture indicator BM31 – finally available again!

BM31 Moisture Meter

Almost as soon as we brought it to market, the new humidity indicator was sold out. That’s how convincing its advantages are for determining the moisture content of building materials and timber. This and with the device’s new design provided good reasons for it to be sold out so fast – but as of right now, the BM 31 is available once again!

NEW BM12 and BM21 Moisture Measuring Devices

Moisture Meter

Only wood that is sufficiently dry should really be used as a building material or as firewood. With moisture levels over 20% in woods used for construction there is a risk of significant crack formation, and for firewood, there is risk of damage to health as well as to fireplaces.

The solution: check the moisture content quickly and easily with our new BM12 and BM21 moisture meters – and not only for wood.

Put another log onto the fire will you Ethel?

Alright, dear. But only if you check it with the BM20 first.

This week has certainly been MultiMeasure week! Yesterday we decided to settle the discussion regarding which series is the better of the two – the MultiMeasure Basic Series or the Multimeasure Professional Series – and came to the conclusion that neither is better. Each series is designed for different applications, different users and different budgets with both series offering simply unbeatable value for money and superb quality into the bargain. And the day before that we elaborated on the benefits of having a series for professionals designed by professionals who come from the same fields and who are able to read the needs of their clients like no others and provide them with just the right tools for their own individual applications.

Well, today we would like to draw your attention briefly to a particular device, a device which you would normally think you wouldn’t be needing until much later in the year. The BM20 moisture moisture from Trotec is yet another extremely useful and affordable measuring device straight from the Multimeasure Basic Series. The BM20 mositure meter is designed to measure the amount of moisture in a number of building materials and – here comes the interesting part – a whole selection of different types of woods. Wood used for building, wood used in carpentry and cabinet-making, wood used in furniture construction – and firewood.

Firewood is not just firewood. Firewood normally has to be stacked properly and sheltered from the rain so that it can dry over a longer period before being used as a source of heat, comfort and fuel. Wood that is properly treated is called seasoned firewood and has a moisture content that lies between 20 and 25%. If the wood you have bought, collected or cut is burnt while it is still too moist, then you do not only run a real risk of ruining your chimney, you even risk setting your house on fire. Wet firewood does not only burn badly – the wood is not able to unfold its full heat potential because the excess moisture in the wood turns to steam and mixes with the other gases, thus stopping them from igniting and generating the heat they normally would produce – it can be extremely dangerous too. The soot or creosote that forms on the inside of the chimney is highly combustible. That means it can literally erupt into a fire of volcanic proportions.

The best way to prevent such an event from occurring is to season your firewood properly – and to check that the moisture content is not too high. If you buy wood from a supplier for the first time or from somebody who is selling ready-to-burn firewood at a suspiciously low price, then it is always better to check the moisture content first.

By the way… wood burning is ecologically friendly. The carbon dioxide that is released during the burning process lies dormant in the wood and would – if you wood pardon the pun – also be released into the atmosphere if the wood were to remain in the forest and rot.

Stop mould before it starts – with a dehumidifier from Trotec

Mould in the home is often a problem. Whereas people of old used to grumble about their draughty abodes and grouse about inadequate insulation, today’s homeowners often make the mistake of casting out the Devil with Beelzebub and sealing their houses so well off from the outer world that although they don’t let the cold, wet air in, they don’t let the warm, moist air out either. This phenomenon quickly provides the ideal breeding ground for different kinds of mould and mildew, which thrive and flourish in damp and stagnant conditions.

Mould in the home is not only unsightly, it is dangerous too. Mould patches on walls or ceilings often spread out rapidly and develop unpleasant odours – in extremely bad cases, the biting, musty smell which is generally attributed to household mould can become so overpowering it even makes your eyes water. Mould spores are particularly aggressive, because they affect the respiratory system and trigger respiratory illnesses or other complaints and disorders. If left unchecked mould can also cause extensive damage to your property and possessions: valuable furniture, carpets, clothes, books, collections and tapestries all suffer to such an extent under the effects of mould that they can actually be rendered worthless. Mould can induce wood rot, which in turn can lead to structural damage to your property. In some particularly devastating and tragic cases when mould was on the rampage, whole families have had to leave everything behind and flee their houses in a last attempt to salvage their health, even at the cost of a once-loved home.

Mould should not be ignored. As a rule patches which are less than 1m² in size can be cleaned with special cleaning agents – and special clothing like gloves and masks! But mould has the habit of returning, not least of all because it is the symptoms and not the cause which are being fought.

One such cause is poor ventilation. Although there are many people who would believe that the onset or spread of mould is a sign of poor hygiene, it is much more a sign of poor airing. Bathrooms especially are prone to being affected by mould, because they are quite simply not given enough time to dry out. The moisture which ladens the air after a shower or hot bath condenses on the colder surfaces in the bathroom – like outer walls or ceilings – where it later becomes a damp spot, thus providing the breeding ground mentioned earlier.

So why not prevent mould from occurring in the first place? With a dehumidifier from Trotec.
