About Us


Art Preservation Services (APS), founded in 1988 by Steven Weintraub, specializes in the environmental preservation of collections in museums, archives, and historic buildings.

We are actively involved in the research and development of tools and products to aid the preservation and conservation communities, focusing on topics relating to relative humidity (RH), light, air pollution, monitoring, data logging and environmental condition alarms.

APS has developed unique systems for the passive control of RH within exhibition cases. In addition, APS has created innovative solutions for evaluating leakage rate and location of leakage in sealed showcases and storage units.

APS provides extensive environmental consultation services to museums, historic houses and private collections. Our areas of competence cover a broad range of specialties, reflecting decades of innovative research and practical problem-solving activities in the field of preventive conservation.
