Please bear with us as we are in the process of putting our Air Conditioning Tools Catalogue in a downloadable format, please check back or send us an email asking for us to send you the catalogue and as soon as it is available we will forward it onto you.

We will also be launching technical and general information to be downloaded in the near future. We are also looking at setting up a members area offering discounts and special offers, if in the meantime you would like to receive emails offering special offers please fill out the form below

To determine temperature an IR thermometer gathers IR energy from an area and converts it to a temperature. To determine how much area a thermometer detects, divide the distance to the target by the Cone of View of the thermometer. For example, if the ratio is specified at 10:1, at ten feet, the thermometer sees a target of 1 foot across. The thermometer averages the temperature of everything in the cone of view, no matter how far away

A dull black surface lets IR energy escape from an object easily. The emissivity is close to 1 (or 100%). If the surface is shiny, such as wet copper pipe, the IR energy can’t escape easily, much is reflected back into the target, the emissivity is lower than 1. The IR energy emitted is no longer proportional to temperature. To get an accurate reading, you must change the emissivity of the target by putting dull/dark tape on it. Shiny targets can also reflect IR energy from other objects into the thermometer, making an accurate reading impossible
