The 4-IRMAN infrared thermometer detects infrared energy emitted by an object and outputs it as a standard signal (4-20mA) or RS-485 communication signal, with an alarm relay contact and external laser control. Consisting of an infrared sensor and signal module, it offers real-time field measurements within a range of -60 to 380 degrees, adjustable for various objects. Its high measurement accuracy, facilitated by an optical lens and a 12:1 optical resolution for distant targets, allows precise readings. Adjustable emissivity (0.10 to 1.00) enhances versatility for materials such as plastics, fluids, rubber, coatings, and more—suitable for industries involving paper, asphalt, ceramics, wood, fabrics, glass, and food.
