KELLER MSR is an independent division of KELLER HCW GmbH, a company with a rich tradition of technical excellence and entrepreneurial spirit that goes back more than a century. KELLER MSR is divided into two divisions, ITS (Infrared Thermometer Solutions) and IAS (Intelligent Automatic Solutions). Since the takeover of the “Pyro-Werk GmbH, Hanover” in 1968, the department ITS develops, produces and sales precision instruments for non-contact temperature measurement for industrial applications and measurement laboratories. The department IAS creates complete automation solutions for processing and visualization of production facilities for mixing, dosing and material handling.
