This time including (page 15): the project of the room climate stations for Kindergarden and elementary schools [blog post from 11.08.2016], at which the state capital Saarbrücken has equipped the main rooms with 500 FISCHER instruments on a special designed rigid foam board.
Introducing the project at the international annually conference hold by the climate alliance in Krems an der Donau 2016
“The main goal is an early education and understanding for environmental matters and a awareness for the meaning of environment protection. The furnishing of the kindergardens and schools shall bring that also to the smalles kids and get them used to take care about their surroundings on a playful way. Because of the design of the board the children get to know about their room climate even before they can read numbers and letters.” explains Claus Schrick, climate protection manager of the state capital Saarbrücken. After half a year he draws a positive balance and hope that other cities will follow his idea and copy that project.
Meanwhile it wasn’t a coincidence that Schrick used measurement instruments from FISCHER for the project: “Because of the mechanical and nearly maintenance-free instruments the educators don’t have to change batteries regularely and prevent additional waste.” the Diplom-Ingenieur Schrick says.
The manufacture of fine mechanical measurement instruments requires precision and solid technical skills. Virtually all product components are manufactured and assembled in-house. The short movie gives you an idea of our craftsmanship.
For years the ecofort GmbH Nidau (CH) familiar on the synthetic hair hygrometer from FISCHER. Now this hygrometer is used for the conservation of West African desert crocodiles:
The ecofort GmbH supports the efforts of Michel Ansermet (research associate of Aquatis, the formerly Vivrarium de Lausanne) to preserve the West African desert crocodiles from extinction. In Europe there are only 3 such crocos, in Lausanne is the only couple. While there were 1946 in Africa more than one million of them, today only 1,500 to 3,000 of these animals are counted.
“Which hygrometers are the most precise, the ones with real or synthetic hair?“ Mr. Wolfgang Pech asked us.
The measurement accuracy of a hygrometer is not just influenced by the kind of hair which is used. It is much more important how good the humidity addicted length variation of the hair is transmitted to the needle. So you can’t say that real hair is always more or less precise than synthetic hair.
The decision which kind of hair will be used is depending of the operating site of the hygrometer:
FISCHER Echthaar-Hygrometer 111.01
Real hair hygrometers react really fast at humidity changes and are also good to use at low temperatures (operating area: -35 … +65 °C). They are the only mechanical hycrometers to be used senceful below 0 °C. Everything else would react way to sluggish. Indeed the indicator stability of a real hair hygrometer is just given if the hair regenerates regularly. For that it needs to be in high humidity. This is no problem with outside used hygrometers as the humidity during the night is naturarely high. In this case no maintenance is needed. At inhouse use that is not given why it is necessary to put the hygrometer into high humidity minimum once in three weeks. One method is the so called “humidity package”: Put the hygrometer in a warm and humid towel for at least 30 minutes. You could take it to the bathroom with you while taking a shower. Or leave it outside during night.
As the maintenance effort is relatively high, we suggest the use of an hygrometer with synthetic hair for indoor climate measurement. It also can be used at higher temperatures (normal 0 … 70 °C, but also up to 120 °C with special pretreatment, for example in saunas). The synthetic hair is free of maintenance effort, you don’t need to get it humid regularly. But we still recommend to do it ones or twice a year.
Since foundation in 1881, the company LUFFT delves with development and production of climate measurement products. In 2012 LUFFT got awarded as “Marke des Jahrhunderts” (brand of the century). The production of all machanical measurement instruments is outsurced to FISCHER from Drebach.
The waether pillar is a faithfully reproduction of an historical instrument by LUFFT. Developed in the 1940th, it was mentioned the first time in the 1951th catalogue.
Historische Lufft Wettersäule
The reproduction through the engenieurs of FISCHER happened in 2014 and got lizenzed the same year by LUFFT.
The product contains the most important measurement instruments of weather forecast:
Barometer for measurement of atmospheric pressure
Thermometer for measurement of temperature
Hygrometer for measurement of relative humidity
Compass for determination of wind direction
The mechanical measurement instruments arranged cylindrical and framed in a body made of polished brass. The aneorid barometer ist installed in the bottom of the case. With the help of the rotateable needle you can easily see change on airial pressure. Hygrometer and bimetallic thermometer are located inside a glass tube and the compass is integrated in the top of the pillar. The bottom of the whole instrument is made ob wood and contains a description of the most importand rules of weather measurement and forecast.
Manufacturing at FISCHER happens in man made single production after an order.
Every weather pillar is hand made and got it’s own serial number.
Distribution in Central Europa and UK will be organized by MANUFACTUM.
