S61 Unique Features


Revolutionize the way you interact with the world around you with the power of thermal just a touch away. Be among the first to bring this accessible thermal imaging technology to your workplace, your home or even on-the-go with the Cat S61.


The Cat S61 gives you live thermal imaging expertise direct from your smartphone. The S61 can locate heat sources up to 400° even in complete darkness. Utilizing MSX Technology exclusive to FLIR, the S61 smartphone captures shareable clear thermal imagery, video and even time-lapse footage. Multiple spot meters allow you to retroactively pinpoint a temperature in your image while the thermal imagery technology is capable of penetrating even obscurants like smoke.


The Measure app on the Cat S61 uses the device's in-built laser and rear camera to establish depth and calculate distances. It can be used to measure the distance from the device to a surface, and to estimate areas on that same surface. The Measure app helps you to capture images on site that can then be used later to estimate sizes and dimensions. It's a convenient way to take on-the-job measurement estimates, without a tape measure. It's the perfect tool for tradesmen, DIY enthusiasts, interior designers, estate agents or realtors, home insurance assessors, and many other professions. 


Get useful temperature and humidity readings with the integrated indoor air quality monitor of the Cat S61 smartphone. With the Air app on the device, you can quickly understand the moisture levels in your working environment. Equipped with a built-in indoor air quality sensor, the S61 can monitor the air conditions around you. The Air app shows you the detected level of indoor air pollutants (VOCs), commonly found in products such as solvents, glues, paints, and cleaning agents. The sensor checks the air quality every four seconds, when activated, and can alert you with a notification when VOCs hit unhealthy levels. 

The S61 can also take underwater photographs and video, as well as boasting a glove and wet-finger compatible  Corning Gorilla Glass 5 touchscreen.
