Extech 42500 Mini Infrared Thermometer

I love this Thermometer. It is works so well and so easily. Just point and shot really. You have to probably do it several times to get an average reading, but it is great for checking the refrigerator temperature, outside temperature. Outside, it is amazing to see the difference in the concrete and say the grass...or under a tree. I'm using it also to check my AC vents. It is just a nice useful tool to have around the house. Helps you check temperatures before calling a professional to fix something like your refrigerator or AC.I go walking my two mini Dachshunds and I bought a Pet Stroller. I have used it to see what the temperature is inside that stroller, with the mesh zipped up...the girls get so hot walking after 2 miles and I didn't want to put them in a stroller that would contribute to their over heating. The girls get to cool down and rest and I get to continue my walk. It worked out great...peace of mind is a wonderful thing.

This is the worst, this is my second infrared Thermometer wish I had not given my first away. I will never buy this brand again. At five inch's away the laser is off by 1 inch. useless laser pointer.I've lost the receipt so this ones going in trash. What a waste of eighty bucks.

Haven't found it's true potential, but It defines hot spots in the oven, and cold spots in the refrigerator and if the double pane windows are working or not.

We got this to trouble shoot a cooling system problem. It was useful for that, as we could quickly read the temperature of air coming out of vents. It has been very useful in identifying winter air leaks, measuring the temperature of food in the kitchen (very instructive about what microwave ovens do and do not heat up), and for making soap, candies, and other temperature sensitive concoctions. It gives an instant readout. Very useful gizmo to have, reliable, works exactly as advertised.

I bought this for an arcane research application (for which it was fine), but found it was also useful around the house. As we'd had trouble with A/C units and airflow in the vent system, I used this IR thermometer to check the outflow temperature and the wall temperatures around the rooms. It's easily precise enough for such uses, and other reviewers have already mentioned other home uses.

I use the unit in the making of high heat confections. Modern microwave units do not have a high temperature sensor (300 degree) making accurate and predictable results unreliable. To get accurate readings from the unit, I remove the pyrex container from the microwave, point the Extech at the center of the mixture and know the exact temperature instantly. It is a good little unit that delivers on accuracy and convenience.

The Output A/C temperature should be about 59 degrees (cooling) and 100+ for a Heat Pump or 120+ degrees for gas heat at the Ventilation Register. Keeping track of your own system's performance saves on calling the Repairman needlessly.Measure the temperature inside your refrigerator to make sure it is cooling sufficiently and the freezer, too. If it's too high, save money by vacuuming the coils on the back or underside yourself to avoid component failure, again saving money on Service Calls.Check the accuracy of your Heat and A/C Thermostat. If it is off, utility bills can escalate.Great little investment that we use frequently.

I cook every night just for my husband and myself and this has become a must use tool. Makes it easy to know exactly when to put your meat in the pan for just the right searing, saute, etc. No more soaking up olive oil if the pan is not hot enough, or splattering EVOO everywhere if it's too hot. Highly recommend.
