The collection, analysis, and record keeping of data in the museum environment is now standard practice in most institutions and private collections. Different types of art and valuables require unique environments to insure their stability, and these devices allow one to monitor the environment is in keeping with the desired conditions. Maintaining a proper environment and keeping records of such are also very important for insurance requirements. These devices are now affordable to most, and we all have the tools to monitor and collect data where art and valuables are stored and displayed. Most measure temperature and humidity. However the Elsec collects data on temperature, humidity, visible and UV light. When using these devices the placement is very important to ensure accurate results. We recommend that you position them above floor level, away from direct flow of air vents, away from heating, cooling or humidity control equipment and not adjacent to doors & windows.
