Thlevel Digital Thermometer Temperature Monitor with External Probe for Fridge Freezer Refrigerator Aquarium 4 Pack Black

Placing the probe into the vehicle dashboard air vent and then trailing the readout to the bonnet, helps check on AC gassing progress. The readout updates every few seconds so you can see any temp changes. Unit was so useful, I've stuck it to my own dashboard and vents so I can see how cold the AC air is all the time.

Spot on

These thermometers do what they are required to do. There is a difference of 0.6 degrees between them at a room temperature of around 19 degrees so they are quite accurate, more than adequate for most purposes. I would have liked a longer sensor cable for the purpose I want to use them for but I can always extend it myself. The display is very clear. Battery life remains to be seen but I have previously used similar ones in which the battery lasted over a year. At the price they represent very good value for money.

Good quality good item

These are such great value and the temperature measurement is accurate. I used these to help me balance my radiators. They are good quality and the battery life is good.

I use this kind of thermometer for my espresso machine (set to the grouphead with Sugru thermoset clay) and replaced mine with one of these yesterday.Unfortunately I didn't realise the refresh rate would be 8-9 seconds as every one I'd bought before was 1-2 seconds. I checked and can't see anything on the product page to say what the refresh rate is.The quality seems decent enough and it's just as simple as similar ones, but the slow refresh rate might be a real breaker if it causes me to miss the correct temperature to pull my shots. The first one I brewed today ended up looking good (see picture), taste was OK, but not great.

as per description came quick no issue

To get 4 thermometers at this price is amazing value. Out of the four thermometers supplied, one had a reading around 1C higher than any of the others which were otherwise all within 0.2C of each other. When comparing readings with the other thermometers, it seems that the high reading thermometer was an outlier and I am very happy with the other three.
