Thermal imaging tech manufacturer Flir Systems has revealed its new camera attachments for Android. The Flir One cameras connect to smartphones via a USB Type-C port to take thermal photos and videos or provide a real-time look at the temperature range of an object or scene.

The third-generation of the Flir One features an all-new image processor, a higher resolution camera and is less expensive than its predecessor from 2015, launching for $199 compared to the $250. In addition, the new model has an adjustable dongle which allows it to be used when the smartphone is housed in a case (this previously required use of an adapter).

The company has also introduced the Flir One Pro, an even more durable version with a more powerful thermal sensor. As the name suggests, the Pro version is targeted at professionals with more specific functions like “multiple spot temperature meters” and “one-touch reporting capabilities”

The Flir One Pro will go on sale for $399 and both it and the third-generation Flir One will be available in the first half of 2017.
