Brannan 12/413 Dial Max Min Thermometer Hygrometer Humidity Meter

My friend and I each have one, and they work well and are attractive looking

Over the years I purchased quite a few Hi Low Temperature Thermometers, all of which have been the now discontinued mercury style affairs. The glass tubes are always far too delicate, and more often than not they break too easily. I've bought several Brannan products over the years, and they have all been excellent quality, and very accurate, so when I saw this rather attractive round needle thermometer, I thought I might give one a test run. The rear casing is made from good quality ABS plastic, if it was metal then the metal coils that react to temperature change would give an inaccurate reading. The main body of the thermometer is a nice metal bronze antique style affair, very clear to read, and the three hands,coloured black,red and blue are also made of metal. Setting both Hi & Low temperature needles is very straight forward, but the main black temperature needle gives a surprisingly accurate reading, that due to its design takes quite a while to settle. That is a good thing, because you know the temperature is being measured carefully. Even the small humidity gauge beneath, responds slowly, and quite accurately as well,compared to the very accurate digital Oregan Scientific weather station on my wall, it works well considering it's a very basic leaf spring construction. Without having seen this temperature gauge in the flesh before purchasing it, there was always a risk that the £13 had been too much to pay, after all it does look very nice in the photographs, but thankfully it represents very good value for money, and above all it's very accurate and if cared for properly should last many years. Always a risk buying a product without seeing it first, but it turns out this was money very well spent.

Cumple su función aunque, lógicamente, no se le puede exigir una precisión extraordinaria. Es elegante, se puede colgar fácilmente en cualquier sitio, o situarlo sobre algún apoyo. Prácticamente no necesita más instrucciones que las que trae para configurar el inicio: poner las manecillas roja y azul en su lugar para empezar. El agarre para mover la manecilla azul (mínima), iba algo duro al principio. Luego hay que dejarlo unas horas para que se estabilice y ya marcha solo. Para hacerse una idea de temperaturas y humedad, más que suficiente.

I haven't yet managed to fit the Max/Min thermometer as it only has a keyhole shaped mounting hole and my greenhouse has an all metal frame. I will need to make up a backing plate to which I can fit a screw for the instrument to hang on, and at the same time allowing the backing plate to be attached to the metal structure - somehow and I haven't yet come up with anything suitable. The greenhouse structure is all aluminum as are the screws that hold it all together. These screws are all cut to length so that there is nothing left to which I can attach the plate to. This is annoying as the instrument looks great and is well made and my old Max/min mercury/alcohol thermometer has worn away internally and so does not register accurate temps any more.

Dit bleek de enige die zonder batterijen een min max functie heeft én een hygrometer. Hoewel hij er naar mijn smaak te klassiek uitzag krijg ik best wat complimenten over de stijl. Bediening is eevoudig en hoewel de hygrometer soms verstopt zit onder de wijzers is hij makkelijk af te lezen. Wordt gebruikt in de polytunnel.
