Eidyer Digital LCD Thermometer Temperature Monitor with External Waterproof Probe for Refrigerator Aquarium, Fishtank Water Temperature Thermodetector -Black, 4.8cm×2.8cm×1.5cm

- The compact size is a real winner. It fits perfectly in tight spaces, making it super convenient for my fridge and aquarium setup.- The external waterproof probe is a lifesaver. I can easily monitor the temperature without worrying about water damage, which is a huge plus for my fish tank.- The LCD display is clear and easy to read. No more squinting or guessing, just straightforward temperature readings.- It's user-friendly and straightforward to set up. No complicated instructions or fiddling around, just plug and play.**Could be better:**- The build quality feels a bit flimsy. A sturdier design would give more confidence in its durability.- The cable for the probe could be longer. It limits placement options, especially if the power source is a bit far.- Battery life could use an upgrade. It drains quicker than expected, so having to replace batteries often is a bit of a hassle.

It came with duff batterys but it is a good product anyway

Works as is says

I must say at the start that it is smaller than I was expecting being only 5 x 3 cm in size, but it is very easy to read the display which is bold and sharp.Having tried it out on freshly boiled water from my kettle, I was impressed to see how once the temperature read-out had quickly climbed it then started to slowly fall back again as the water cooled (it went into a cold cup in a cold kitchen) so I have no doubt of the units ability to rapidly reflect real-time temperatures.The sensor is appx 2cm long and slim enough to any thin tubing you may need to access.The attached cable is long at 100cm long from tip of the censor to the point it enters the display unit.Only, very small negative is that there is no on/off switch so the display stays on all the time which may drain the 2 x LR44 batteries (supplied), but I get around this by simply taking the batteries out when not in use.I bought this so we can check we don't have the bath water too hot and am confident it will do this task well and am happy to recommend this product.

In the description it states 5m. It’s about 1.5m. I needed it to be 5m so Amazon refunded.

It does the job at a good price, just wish It had an on/off switch so i wouldn't have to keep removing the Batteries Which is fidgety.

Lots of length to probe it anywhere you want and I like how the screen has little clips on the sides to place it into a box or anything you want to slot it into

Bought it about one year agoStill worksCan measure water temperature and air as well
