FLIR TG165 Spot thermal camera review

FLIR Systems, Inc. is the world’s largest thermal imaging company. The brand speaks for itself as they produce some of the most advanced thermal imaging solutions. Their products range from handheld thermal cameras to thermal security cameras, thermal scopes, and many others. 

Sitting right in the middle of single spot infrared thermometers and traditional thermal cameras is FLIR’s TG165. This handheld thermal camera consists of a real-time thermometer and a thermal camera to complete the picture. Thus; its only purpose is to identify cold and hot spots and take thermal images allowing you to detect problems quickly.

Thermal Imaging Features

The TG165 is a sophisticated device that uses two laser pointers to project an image on the area you are viewing. It can measure temperatures as close as 4 inches with a temperature range of -130F to 7160F. With such a wide temperature range, there’s no place you can’t use TG165 from your home to the car and even areas with extreme temperatures such as industrial equipment.

The spot thermal imaging camera uses a Lepton IR Imaging Engine with an 80 x 60 pixels resolution. It is capable of rendering powerful images with crisp, clear details for quick examination. This means determing the root cause of issues will be easy and you or your clients can know the location of air leaks and insulation loss in time for repairs.

The two laser pointers are useful when it comes to complex objects like switches and circuit boxes. Instead of opening them and risking short circuits, its 24:1 spot size ratio lets you point the thermal camera and see what’s behind the circuit box or wall from a safe distance.

The TG165 has a 9Hz refresh rate. It comes in handy when moving your hand so that you will not get choppy images a marred picture although you will need to move slowly. It is also focus-free so no messing with lens rings for focusing. 

Wide Field of View

This budget thermal camera boasts a 50-degree field of view. When you have a wide area to cover, all it takes is one scan, and you can have a large image of the area an instant. Say you are scanning a wall or ceiling; you won’t be passing the camera twice when you want one picture that shows all thr information about an object. 

Display and Controls

You will appreciate that the FLIR has used a TFT color screen to display the thermal images. It has three color palettes including iron, gray, and rainbow. If you are looking to see different aspects of an image, changing the color palettes will tell you more about the image. 

The TG165 is very straightforward to control. You do not need any training, so you only need to familiarize yourself with the controls and start enjoying the view from the thermal camera. It has one large trigger at the center of the handle, so you can use it with one hand. 

It is ergonomic allowing for use for a long time without fatigue. The other four buttons include the power-back, two arrow keys, and a menu-OK button. It is easy to start using this thermal camera right out of the box. 

Save your Images

The TG165 has an SD card slot. You can save up to 8000 images on the included 8GB SD card. This is more than enough for most applications. But if you need more space, you can always install a bigger SD card up to 32GB.

To transfer your images from the SD card you will need a USB cable which is included.

Compact and Durable Design

One of the appealing qualities of this device is the rugged construction. It has a robust body that can withstand a 2-meter drop. It can be used around hard floors where you will not be worried when it hits the floor a couple of times. 

You can use the TG165 with the included lanyard as well, so it can stay around your wrist. It can also be mounted on a tripod thanks to the tripod mount. And when it is time to leave the work site, the thermal camera will stow easily in a toolbox without risking damage to the screen or the exterior surface. 

Battery Life

A rechargeable 3.7V Lithium-Ion battery powers TG165. The battery charges using a USB cable from an AC power source or USB power from a computer. The device will show different icons for the two different power sources. 

This device has a running time of five hours during continuous use. To save on the power, the device can power off automatically by selecting a time period on the menu. It can be 1, 2, 5, or 10 minutes of inactivity.
