It does the job. 2 nice rolls, will probably last me a lifetime. Easy to use, nice size for small projects.

The amount of infrared light emitted by an object is directly proportional to the object's emissivity and the emissivity is dependent on the surface finish. Every cheap infrared thermometer I've seen has the emissivity set to 0.98. The reading displayed is directly proportional to the emissivity. So a polished aluminum valve cover with an emissivity of about 0.02 will indicate over 99% lower than the actual temperature.More expensive guns have an emissivity setting. One can either use a chart of typical emissivities or put a temperature sensor such as a thermocouple on the object and adjust the emissivity to make the physical and thermal temperature indication the same. My quite expensive Omega Engineering unit has an emissivity dial and a thermocouple input for the purpose of setting emissivity.There is a way to make fixed emissivity units quite accurate. That method is to apply some kapton tape to the object. Kapton is almost 100% opaque to thermal infrared light and has an emissivity of 0.99. Simply stick a square of Kapton tape to the object to be measured and point the instrument at the tape.Caution: the cone of sensitivity of the cheap instruments is about 35 degrees. Those with a laser pointer are even more of a joke. To properly measure using a cheap gun, hold the opening as close to the kapton as possible.My Omega instrument has a (now expired) patented feature where it projects a circle of laser dots that expands at exactly the same amount of the infrared sensitivity. It actually contains infrared optics to focus the infrared beam on the pyrosensor instead of simply leaving the pyrosensor open toward the meter inlet.Since the patent has expired some chicom company has knocked off the instrument. I bought one to see how it ($25 price point) compares to the Omega's $350 price point. Two things I dislike right off the bat are that the emissivity must be entered with up and down keys instead of a knob and that the physical temperature sensor is a thermistor instead of a thermocouple.So far, the two have similar performance. But I'm interested in how they do over time. $350 gives Omega room to use precise, low drift and thermally stable components.Even with the Omega, I still use Kapton tape whenever I can. And this particular product has high temperature stable silicone adhesive so it'll stay stuck on hot parts. Up to 500 deg F according to what I've read elsewhere.Highly recommended.
