Extech 39240 Waterproof Stem Type Thermometer

This is really a good buy if you are looking for a reliable and accurate thermometer to measure liquids, food and even ambient temperature. Has worked faultlessly.

Purchased to carry out household water temperature tests and works a treat. Seems quite accurate and does the job splendidly. A very good and handy purchase. Used for LD risk assessment.

I love it2 years latterI have use it for two years and it is great stuff for sure.. after this time and so many work and wash, lid for battery come loose and water come in, dry out and 5 month again, but the battery cover is hold in only with very small plastic, which break out at all so I need to use tape for presing the battery in, but it is still working well... any way, this kinde of probs are all same system and all battery have very similar cover. I can still recomend it..

We use it at a property to accurately get the water temperatures on taps and showers, it does proof very well against the much more pricy options professionals in the mechanical field do use.

Recommended by Amazon customer review and perfect for task,Arrived on time as planned

I purchased this product to take some water temperatures. Straight out the package the display kept flashing on and off. I replaced the battery and the display started working again. This lasted for a whole five minutes and then it died! Don’t waste your money. Spend a bit more and buy something more robust.

quick delivery, perfect for doing the water checks at community hall, easy to read and use

After two months of use outside and in water this failed. I checked the battery and found out that it was totally corroded. Also seems like water has got inside the display.Was never convinced of the accuracy - seemed to be reading around 3 degrees C too high
