Grab and Go Simplicity
Fire It Up and Get to Work in Seconds
Rugged and Reliable
Designed for the Harshest Environments
The FLIR TG165 Imaging IR Thermometer bridges the gap between single spot infrared thermometers and FLIR’s legendary thermal cameras. Equipped with FLIR’s exclusive Lepton® micro thermal sensor, the TG165 lets you see the heat so you know where to reliably measure it. Easily find unseen hot and cold spots for instant troubleshooting, and store images and data to show customers and include in reports.
Thermal imaging is one of the most powerful technologies ever developed to enhance visual perception. The unaided human eye can only perceive a very narrow band of visible light along the electromagnetic spectrum, which also includes radio and microwaves, infrared and ultraviolet light, X-Rays, and gamma rays.
Thermal energy—or “heat”—resides within the infrared spectrum, which is invisible. However, a spot thermometer sensor is capable of converting thermal energy into a temperature measurement, and a thermal imaging detector converts thermal energy into an electronic thermal image that can be viewed on an LCD screen.
The TG165 utilizes both of these types of infrared technology, simultaneously. The spot thermometer emits a beam of infrared light that lands on an object and then bounces back. The thermometer determines the object’s apparent surface temperature based on how much thermal energy the object is emitting, reflecting, or transmitting.
The TG165’s thermal imager, on the other hand, includes a micro thermal camera that can passively scan an area and display images of hot and cold patterns on an LCD screen. Being able to “see” infrared radiation creates an entirely new level of awareness for professionals and consumers, alike. Users no longer have to guess where to take temperature readings. They can literally see hot and cold spots, making work more efficient and reliable.
The TG165’s IR thermometer has a Distance-to-Spot ratio of 24:1. In other words, from a distance of 24 inches (61 cm), the TG165 can measure the temperature of a one-inch spot (2.5 cm). If you double the distance to 48 inches (122 cm) the spot diameter will expand to two inches (5 cm), and so on.
The amount of thermal energy emitted by an object depends upon its temperature and how effi ciently it radiates thermal energy. This efficiency is called “emissivity.” Emissivity values range from 0.1 for very reflective material—such as shiny metal—to 1.00 for a pipe with a flat black finish. The TG165 has both adjustable and preset emissivity settings, and the TG165 user’s manual includes a list of common materials and their respective emissivity factors as a quick reference for users who are not trained in thermography.
Bridging the gap between single spot IR thermometers and FLIR’s legendary infrared cameras, the TG165 gives you the advantage of thermal imaging to help you discover temperature issues you can’t see with typical spot radiometers. You’ll work more quickly and have confidence you won’t miss anything vital.
Equipped with FLIR’s exclusive Lepton® micro thermal camera, the TG165 helps you identify heat patterns, reliably measure temperature, and store images and data for reports. And with a spot ratio of 24 to 1, you can take accurate readings from safer distances. The TG165 is simple to operate, featuring intuitive menu icons and dual laser pointers. Built by the world leader in thermal technology, the durable TG165 will quickly become your “go to” temperature tool.
