NUREMBERG, Germany — Amprobe, TIF, and Promax remain familiar names to hvacr contractors. And even though those three names are now under one company name, Advanced Test Products (ATP), plans are to continue the unique identity of the products.

The change, according to ATP president Hermann Hinterhauser, allows ordering and billing to be done under a single company name. Hinterhauser said the system was designed to reduce time and paperwork for supply houses and contractors.
