Ever since the launch of Autel's ever-so-popular EVO II Dual, we receive a very frequently asked question, "Is the EVO II Dual's thermal sensor radiometric?". Well, the answer is unfortunately no. Autel leveraged their partnership with FLIR Systems who OEMs for and supplies Autel the FLIR Boson 640 thermal sensor for the EVO II Dual. The Boson sensor core unfortunately is not radiometric, and at the current time, there is no radiometric version of this particular core. However, this discussion is to be continued as there is some further explaining to do to clear up some possible confusion. Keep reading...
But what about the EVO II Dual 640T?
Recently, Autel quietly added a new model to their website called the EVO II Dual 640T. We say quietly because this model was introduced for other markets around the world, and not for the United States or North American market and honestly it hasn't been talked about by many. As of right now, this model is not available in the US or NA market. International readers, you can find your international dealers for the EVO II Dual 640T here. Sure us in the United States could probably buy it from a dealer in a different market and get it shipped to the US, but your warranty would be for the country/region in which you purchased it, and because the 640T it not available here in the US, Autel USA (headquartered in Bothell, WA) cannot provide warranty service and support for the platform.
What does the "T" stand for?
You guessed it! 🥳 T is for radiometric. The EVO II Dual 640T model does have a radiometric sensor, but it's not a FLIR sensor like we're used to and what most users prefer so they can use FLIR Tools. The 640T's radiometric sensor core makes the platform capable of features such as temperature measurement, thermal analysis, temperature alarms, and image enhancement.
EVO II Dual vs. EVO II Dual 640T
So, now that we know what the 640T is and we know what the "T" stands for, let's discuss how the EVO II Dual 640T model differs from the EVO II Dual. First things first and just to reiterate, we've got a radiometric core with the 640T, non-radiometric with the standard EVO II Dual 640. The EVO II Dual we offer in partnership with Autel Robotics USA is certified as Made in the USA with foreign and domestic parts and labor, while the EVO II Dual 640T is not and has a county of origin (COO) of China. Autel leveraged a partnership with InfiRay, a Chinese firm that manufacturers thermal sensors, for the camera in the 640T model. We can't speak to the quality of this sensor as these are not here in the US and we've never analyzed data from one, but given our experience and knowledge of US-made FLIR sensor cores, we are comfortable saying that the FLIR Boson 640 in the EVO II Dual is likely better quality than the EVO II Dual 640T.
How about a FLIR Boson 640T Radiometric sensor?
It sounds good to us, but as we mentioned earlier, FLIR currently does not have a radiometric version of their Boson core. We don't like to pass or discuss rumors or hearsay, but it seems inevitable and we've heard some chatter amongst the interwebs that FLIR is potentially working with Autel to bring out a FLIR Boson 640 Radiometric core that could be another available option for the EVO II Dual. Our fingers are crossed! 🤞 This would result in the US and North America market having an EVO II Dual 640T model that would have a FLIR sensor and be compatible with FLIR Tools. This seems to make sense considering that the current 640T model available in other countries and markets currently isn't being made available here...maybe because a Made in the USA solution is coming. 🤷🏻♂️
