Digital Max Min Greenhouse Thermometer - Max Min Thermometer to Monitor Maxim...

Really good and great value. Easy to use.

Exactly what I was looking for. It's in my potting shed which has slopping glass along one side, so it can get very hot. Very easy setup, nail or screw on the wall, ensure battery is in place and put into your chosen position. This thermometer gives me the highest reading at the top, lowest at the bottom and current in the middle, the readings are very clear to read. Easy to reset with the touch of a button.

Needed a second thermometer for a cold frame. Seems to work, but doesn't show the same temperature when tested next to the one (different product) that I've had for over a year. Maybe the one I've had for over a year is the one that's not accurate though..... who knows?

Easy to use easy to read appears to be accurate.

I hope this thermometer lasts longer than it’s predecessors all of which gave up within 12 months

Everyone on my allotment site has these and swears by them! I love mine, perfect for new polytunnel. Highly recommend

Good legibility with large numbers and easy to reset.

I initially made a judgement about these thermometers that wasn't at all favourable based on buying an identical pair and having them in my home for several hours directly after receiving them. I assumed that given the stated ten-second sampling rate the readings would be reliable after half an hour at most. At that stage the readings differed wildly between the pair even though I was testing them sited next to each other. The readings were also far different to a good calibration source. Well for whatever reason the thermometers acclimatised after many hours and the pair now display readings within half a degree C of each other and are well within two degrees of the calibration source, which given the low cost is perfectly acceptable (lab-grade thermometers are very expensive). So lesson learned. I must not be so hasty! Fortunately my initial review was merely submitted and had not reached the stage of being considered for publication. Hopefully this one will be the only one of my two attempts to become visible.
