Hayes UK ST9204 Digital Stem Thermometer is rated 4.3 out of 5 by 3.
Rated 4 out of 5 by from HAYES UK ST9204 DIGi Thermom This item was bought for a village hall, in order to test water temperatures as part of controls to prevent exposure to legionella bacteria. It has only been briefly used at this time, but would appear to do all that it is needed to do. It would appear to provide accurate readings, but is slower to react to exposure to hot water or cold water from ambient than others I have used in the past. If that is the only criticism, then for the price, no contest.

Rated 5 out of 5 by from Digital pocket thermometer For the price, this is a good quality, handy pocket thermometer. My only comment would be the fact that it would have been nice for it to be waterproof. But for that price you cant really go wrong.
