TFA 30.1053 Maxima-Minima Digital Thermometer

I had to work out how to press the buttons but once I did, it turned out that it was very easy to operate. Just hold the left-hand button for a couple of seconds to reset the unit. I don't bother to reset it regularly because it does all the display and recording work automatically.I wanted to control the house's use of heating next winter, so I bought ten of these thermometers. Initially, I placed them all in the same place for a few days and found that they only differed by plus/minus half a degree Celsius. That is more than accurate enough for domestic purposes.I put one outside on the side of the swimming pool, one on the side of the house, one in the garage and the rest in various downstairs and upstairs rooms. I can now control the radiators in the house when the winter comes and am watching the night-time temperature steadily fall by observing the minimum recorded temperature. Altogether, I am very pleased with this product and recommend it to everyone. Thank you.

This is a simple and very easy to use max-min thermometer, running on a couple of AAA cellsI had the opportunity to compare readings with that of a lab grade thermometer and it tended to under read by 1 C to 2 C. For example, it read 3.0 C when the true temperature was 4.7 C; it read 14.0 C when the true temperature was 15.0 C. This may seem a large error, but my guess is this is fairly typical of inexpensive thermometers like this. Probably not an issue for casual domestic use.The construction is reasonably sturdy and the displays are easy to read. It looks reasonably weather resistant but I imagine its not completely waterproof (eg no rubber seals around the battery compartment) so some care in positioning would probably be needed when used outdoor.CONCLUSION: Not bad for £10 or so. Easy to use, reset & read - but be aware that the absolute accuracy isn't much better than a degree C or so.

Reasonable price, clear and simple to use. Takes two AAA batteries in a push on cover so no small screws to fiddle with. Good size clear display showing maximum, current and minimum temperature since last reset. Straightforward reset with raised buttons on the front so no taking it down to press a small indent on the back. Fits on a wall hooked on with a small screw (not included). Made of solid plastic by which I mean not the sort that crack at the slightest knock, time will tell how it manages a few seasons of summers and winters but really can't fault this product.Update: both of these still going strong, still on original batteries and no issues with the weather. Both are hung on wooden posts one on decking another on fence post and no problems with getting wet in the rain, a cold winter will test the plastic but still solid and not brittle from UV

An excellent, easy to read and re-set outside max/min thermometer. Competitively priced.

This item is absolute crap..

Bought this for my workshop so that I would know why my fingers were so cold and could turn the heater on !It has a really clear display and the max and minimum temperatures are useful. sometimes I store paint in the workshop and I like to make sure that the temperature does not fall below freezing.in summary, a well made piece of kit that I have had no problems with at a reasonable price

A good machine - works well. Only snag is viewing angle: to read the temperature, you need to view it from an angle of approximately 45º below the unit.

Bought this to record max and min temperatures in my garden, to replace another thermometer which had failed. Nice clear display and so far (6 months use) 100 per cent reliable. Two caveats - first, it is described as suitable for outside use, but has no seal on the battery compartment etc, so is not waterproof. If you are going to use it outside then you will need to make a little open fronted 'house' or similar to protect it from direct rain. Second, the display only updates every 10 secs or so, so when resetting you need to hold the reset button in til it resets - it doesn't mention this in the instructions and until you twig this it looks like it doesn't wrk properly.....
