Bedfordshire, UK: The Convir ST8839 handheld infrared thermometer from Calex Electronics offers a great blend of high performance and outstanding value, providing an ideal solution for users that need cutting edge technology on a budget. The instrument provides a wide temperature range of -50 ºC to 1000 ºC, and offers adjustable emissivity, a feature often absent on infrared thermometers in this price range. These features combine to give the ST8839 great flexibility and allow it to tackle the vast majority of temperature measurement applications. The instrument also boasts an impressive array of features, including maximum, minimum, differential and average readings. High and low alarms are available to provide quick and easy hot and cold spot detection. Other useful features include laser sighting, automatic data hold, over range indication, a trigger lock and backlit LCD display. The high performance is not limited to the electronics with this new model, a very tight 50:1 field of view allows the ST8839 to measure even small or very distant targets. Each unit is supplied with a hard carrying case for increased protection when in transit and when not in use. These instruments are powered by a standard PP3 9V battery, and have an automatic power off function to help conserve power. Calex Electronics Ltd, Bedfordshire, UK.
