Consulting & Research

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


  • Founded in 1988 by Steven Weintraub  in New York City

  • APS is 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, light, air pollution, monitoring, data logging, and condition alarms. We are presently prototyping new humidification and dehumidification systems.

  • APS developed unique systems for passive control of RH within exhibition cases, and has consulted with many museums on exhibition case design, testing, and trouble-shooting to ensure proper RH control.
