Min Max Thermometer 20cm

I purchased 2 of these thermometers to measure the max / min temps in different parts of my garden. Neither operates properly despite following the instructions. The measuring fluid separates and despite “shaking” to re set they haven’t settled, also the two small metal pieces that are used to mark the max / min temps have disappeared altogether. I would not recommend

Having purchased two of these unfortunately both had unfixable faults. For whatever reason, although similar in appearance, I have found the more expensive aluminium bodied version much better. Tempcon were very good at facilitating an exchange.

Many gaps in liquid column which would not unite even after prolonged shaking

I puchased two. One was satisfactory. on receipt the second one had many spaces in the liquid column. Continual shaking did not unite the liquid column. Poor

Good quality basic thermometer. Would buy again.

Neat thermometer, quickly reset at the push of a button.

It seems simple to use but the instructions talk about something blue and I can't see anything blue.

Columns of liquid keep breaking so you cannot get a proper reading.

Both sides, at different times, were ruined by bubbles where the different coloured columns met. Several occasions. Easily fixed by magnet and repeated shaking, as advised. But who wants to do that nearly every day?

Have tried to shake the columns but even when this is done the columns separate when hanging up on wall. Can't be sure of the correct temperature.

Had quite a lot of trouble with air gaps in the liquid columns, but managed to overcome this. Metal insert do not always go down to the bottom of the columns so you cannot be sure of the exact Min and Max temperatures.
