The Convir Thermosight series of handheld infrared thermometers from Calex Electronics includes models suited for virtually all applications, from monitoring sub-zero freezer temperatures, through glass production, right up to white-hot metal processing. Now, to increase their flexibility they can also provide a USB interface, allowing quick and easy connection to a PC.
Nine different models are available in the Thermosight series, starting with the Thermosight 400, 500 and 600 units. These models have temperature ranges from -32 to 400ºC, 500ºC and 600ºC respectively, and have distance to spot ratios ranging from 10:1 to 30:1. They all have laser sighting, adjustable emissivity, large backlit displays and can show instantaneous, minimum, maximum or average temperature measurements.
The Thermosight 800 and 900 models can measure up to 800 and 900ºC respectively, and both have a narrow 50:1 optics with concentric laser sighting. The Thermosight 800 has internal data storage for 20 measurement values, and the Thermosight 900 plus model can store up to 250 values. The Thermosight 900 is the first model in the series to offer the new USB interface, which can be used for continuous data monitoring on a PC, or retrieving the stored values of the 900 plus model.
The Thermosight GL is designed for use in glass measurement applications, where it's 5.14µm spectral range enables it to measure a short distance into the surface of the glass, cutting out the reflections that can cause spurious readings in other handheld infrared thermometers. This model has a temperature range from 150 to 1800ºC, with focused 50:1 optics and concentric laser sighting. It also offers the USB interface and the GL plus model can store up to 250 measurements in its internal memory for downloading later.
