Regarding the RH of the shop I've been looking for a Dehumidifier/Humidifier that will keep the RH around 40-50 (its around 60 at the moment which my gauge says is in the normal range - but I want to lower it) do they make anything which you can specify the settings you want? If so can anyone recommend any which I can buy in the UK? Many thanks Dave |

There have been a number of threads pointing out that you cannot trust a relative humidity gage unless you calibrate it periodically with a wet bulb hygrometer, which is quite easy to do. The same would go for most, if not all, humidifiers or dehumidifiers that represent a scale on a dial. So, the search will probabaly not be for a machine that has relative humidity printed on a control dial, which would be in error and need calibration. You need to find a reliable machine at a decent cost. You then test the relative humidity with a wet bulb hygrometer after you set the machine and give it a day to equilabrate. Adjust as needed, until it appears stable. The machine will change efficiency with temperature and other factors, so you need to recheck with the wet bulb periodically, even if you think things are stable. You should also have a small electric fan running continuosly. |

Many thanks for the reply! I'll look into wet bulb hygrometer and also start using a fan - thanks for the tip! All the best Dave |

I use a mid-range domestic Hinari Dehumidifier that can draw up to 40 litres a day- On the full setting it can bring a room down to acceptable RH in one hour. Because up in the Midlands, the RH is pretty constant, I have the dehumidifier on a timer switch for certain times of the day. |

Hi Sam Many thanks for the reply! I'm also from the Midlands (Worcester) so I suffer from the same climate as you lol! (always lovely and sunny eh lol - its a small old world!) Many thanks for the recommendation I'll have a look at the Hinari range (is it Currys that stock these?) and find something suitable ![[:Y:]](./images/smilies/smiley20.gif "Thumbs Up") Thanks again!  All the best Dave |
