Suto iTec

We have partnered with Suto iTec to provide compressed air & gas measurement technology to Australia.

SUTO iTEC was born from an idea that compressed air and gas systems need improvement, that end-users were being starved of technology required to manage these systems and that the level of wasted energy needed to be brought under control. Since its inception in 2005, SUTO has grown to be one of the world leaders in compressed air and gas measurement technology and is the market leader in compressed air purity monitoring equipment.
