## Description

Great prices on your favourite Gardening brands, and free delivery on eligible orders.

Review: Stylish, clear and accurate. - I am very pleased with this purchase. I was surprised at quite how big it is - but that is not a problem, the dial is 10cm (4 inches) in diameter. There is a "keyhole slot" on the back to allow the circular body to be mounted on a wall. There is also a separate stand - it has a lug that clicks easily into one of the slots on the lower edge of the circular body (there are 9 slots so the obvious choice is the 5th slot, ie the centre one). The hygrometer can then be stood anywhere you want. It is nice and light, when attached to the stand it is very stable. To remove the dial from the stand, just hold the stand on a flat surface and tilt the dial forwards gently and it will come free with very little effort. Do not try to just pull the dial free. It is primarily a Hygrometer, so the humidity scale is the largest and the temperature is shown on the smaller dial. As shown on the product photos the text on the dial is mostly in German, but numbers are numbers - so there is no confusion. I have a couple of electronic/digital thermometer/hygrometers. The temperatures match within 0.5 degC, and the hygrometer on this agrees with the others to within 2% humidity at 40%. There are instructions in English, although I did not need to try and recalibrate mine, it arrived reading correctly once I left it in the room for about 20-25 minutes.
Review: Good, clear display on this hygrometer. - I am very happy with this hygrometer. It has a large clear face with different coloured zones. Even although the labels on the face are in German, it's obvious what they mean. Calibration - if required - can be tricky as it is very sensitive. It may be best to use a non-metallic screwdriver for this task since the dial pointer reacts to the presence of metal. A small plastic knitting needle with the point altered to a blade would be ideal. According to the instructions, the hygrometer should be wrapped in a damp towel for 30 minutes before recalibrating. This will take the dial pointer to maximum deflection. It should then be set to between 95% and 98% RH, after which it will fall automatically to the correct humidity level for the room. Although the instrument itself is sensitive and accurate, the optional stand is not very secure or robust. Nevertheless, in its price range, this is the best and most accurate hygrometer I have owned - and I have had several different brands over the years. It also has a thermometer in the lower segment of the display, which is very useful.

### ⭐⭐⭐⭐ Looks good, works well!
*by P***N on 26 March 2016*

Great device, no problems with calibration, seems very accurate too. Other reviews have mentioned the stand doesn't fit well with the Hygrometer, I found this too which was slightly disappointing. Since this can be hung up I didn't see this as a massive problem though.
