TFA Dostmann Maxima-Minima Analog Thermometer 10.3014.02 Highs and Lows Weatherproof White L 80 x W 32 x H 232 mm

I had an old mercury one of these for many years - in fact I still have it but the small magnetic indicators don't defy gravity any longer (yes I should have just laid it horizontal!). This one has no mercury (I'm assuming that's considered a good thing) and it works fine. I have tried the ones with LCD display but I suspect the temperatures in a greenhouse get too hot for them. I've tried a couple of these and the segments tend to stop working. It's amazing how important it is to have all the segments working.

The metal stops keep getting mixed in with the red temperature liquid which also keeps separating. I've followed the instructions to fix this * STILL the metal strips remain mixed with the red temperature liquids which also separate.despite shaking the thermometer as instructed in the user leaflet. It is impossible to read the MAX Min as a result & the thermometer is now useless!! A waste of money -DO NOT BUY & VERY disappointing for a product made in Germany which you would think indicated a quality product.This is NOT what I expected

Clear to read with good instructions.

Mine works great! Very happy with it. The very first time I used it, the minimum marker didn't stay put as it should have done but I just reset it and after another warm/cold cycle of day and night it had stabilised. It's easy to use, just be a bit patient and place it upright, reset it and let the liquid in it settle for a day or two

The gaps in the liquid are difficult to close by the normal shaking of the thermometer. Wouldn't buy this thermometer again although I suspect many others suffer the same problem. Not keen on battery operated as they seem to fail quickly

This thermometer works well and appears accurate. The instructions appear translated from German and are not very clear. The thermometer works based on clear fluid expanding or contracting from the *bottom* of the the thermometer up the scale to indicate the temperature. If the columns of clear (note - NOT orange) fluid that indicates the temperature on both scales become "bubbled" the following procedure will correct them. 1) Use a fridge magnet or similar to slide both the metal maximum and minimum indictors up the scale to the very top of the thermometer. 2) Then hold the *top* (NOT the bottom) of the thermometer and shake it like an old mercury thermometer to drive the bubbles from the columns of clear fluid indicator. 3) Press and hold the button until the maximum and minimum metal indicators reset at the top of the fluid. I am glad to find an old fashioned analogue thermometer that is accurate. - I doubt the battery required for a digital will last any time given the temperature variations it will have to endure. No error of measurement is given in the instructions but both scales give a reading of the current temperature consistent with each other and appear to measure within one degree of accuracy. .

I have never written a bad review before but feel that this item is not fit for purpose. I Have had it for a week or so now trying to get rid of bubbling and to get indicators to be in correct position..it does say that after transportation the liquid may be bubbled and that the indicators may need to be positioned by using a magnet to pull them out of the liquid. I have had no success with this and as it is an item of so little cost ( lesson to be learnt there, I guess) I have not got back to seller. Very disappointed as usually one can trust goods produced in Germany . Will wait now to get one locally that I can SEE working .

I'm sending this back. It arrived with the liquid separated it Ie it was all in the top half rather than together in the bottom half. I tried to follow the instructions to return it all in the bottom half. First I had to find a magnet because it said the metal markers had to be returned to the top using a magnet. I did this, then it said to hold the top and shake the thermometer like you do to take temperatures. I tried this a number of times and all that happened is that the metal markers went back down the tubes but the liquid remained in the wrong place. So I am unable to use it as intended and it is going back.

Nach inzwischen mehrwöchiger Nutzung kann ich die vielfach beschriebene Problematik bei uns nicht feststellen. Der einzige Unterschied zu den „guten“ alten Quecksilbergeräten ist das zeitlupenartige Absinken der Markierungen. Man muss für den „Reset“ vergleichsweise recht lange auf den „Knopf“ drücken.

Ne fonctionnait plus après une chute : article immédiatement remboursé. Bravo

Is echt heel erg slecht, ik heb een nieuwe ontvangen omdat de 1e niet afleesbaar was. Echter de nieuwe was na een paar dagen niet meer afleesbaar, er zitten luchtbellen in de thermometer. Dus toen maar weggegooid. En bij andere webshop een andere gekocht./

Livraison très rapide. Article intact et conforme à la description. Parfait !

Doesn't work. The recording indicators either fall down when they shouldn't or don't get pushed up by the fluid.
