When precious artworks require 24-hour care
Museums and art galleries worldwide face a common challenge: preserving artworks in their original condition and value for as long as possible. Even slight changes in temperature, humidity, light, or UV radiation can have cumulative effects, leading to long-term damage to the artworks.
The Saint Louis Art Museum, one of the leading art museums in the United States, chose to use the T&D RTR-574 Wireless Data Logger to continuously monitor and record environmental data. This helps the conservation team track conditions affecting the artworks 24 hours a day.
Why museums need data loggers for art conservation
Each artwork is created from different materials, whether fabric, paper, wood, plastic, or modern materials, and each type has varying sensitivity to environmental conditions.
Key factors affecting the degradation of artworks include:
- Temperature
- Relative Humidity
- Illuminance
- Ultraviolet (UV) radiation
Historically, monitoring relied on occasional measurements, making it impossible to know how much environmental conditions changed throughout the day.
The Saint Louis Art Museum therefore required an Environmental Monitoring system that could continuously record data and store historical data for long-term analysis and conservation planning.
How the Saint Louis Art Museum uses the T&D RTR-574 Data Logger
The museum installed 50 T&D RTR-574 Wireless Data Loggers within its exhibition and storage areas.
The RTR-574 is a data logger that can simultaneously measure four critical conservation values in a single device:
✅ Illuminance
✅ UV Radiation
✅ Temperature
✅ Relative Humidity
RTR-574 Measurement Range:
- Illuminance: 0 – 130 klx
- UV Radiation: 0 – 30 mW/cm²
- Temperature: 0 – 55°C
- Humidity: 10 – 95% RH
It can also calculate accumulated light values (Lux-hours) and accumulated UV radiation, which are crucial data for conservators to assess the risk to each artwork.
Reasons the museum chose the T&D RTR-574
The museum's new exhibition wing was designed primarily to use natural light to enhance the viewing experience.
However, natural light can expose artworks to more light and UV radiation than recommended if not continuously monitored.
The RTR-574 helps staff accurately monitor the actual amount of accumulated light artworks receive and compare it with conservation standards.
Key features that meet conservation needs include:
- Automatic data logging
- Wireless connectivity
- Supports multiple installation points
- Remote data monitoring
- Cloud access to data anywhere
- Email alerts for out-of-range values
This allows the team to detect anomalies quickly before they can affect the artworks.
Monitor data via the Cloud anywhere
The RTR-574 supports connection to the T&D WebStorage Service, a Cloud system for automatic data storage and management.
Users can:
- View historical data at any time
- Check status via computer or smartphone
- Monitor data from multiple locations simultaneously
- Receive alerts when values exceed set limits
This reduces the workload of staff and ensures that storage and exhibition areas are continuously monitored 24 hours a day.
Results from using the T&D RTR-574
After installing the RTR-574 system, the museum can monitor environmental data more continuously and accurately.
Benefits include:
- Reduced risk of artwork degradation
- Accurate monitoring of accumulated light
- Continuous UV radiation monitoring
- Systematic conservation data storage
- Increased confidence for artwork owners and lenders
Claire Winfield, a conservator at the museum, stated:
"Some artworks are extremely sensitive to environmental conditions. Even small differences can accumulate and quickly cause problems. We sleep better knowing that T&D Data Loggers are helping us care for our artworks."

FAQ
Q: What can the RTR-574 measure?
A: The RTR-574 can measure illuminance, UV radiation, temperature, and humidity simultaneously in one device.
Q: Is the RTR-574 suitable for conservation work?
A: It is ideal for museums, art galleries, libraries, and places that require environmental control for conservation.
Q: Can data be viewed on mobile devices?
A: Data can be viewed via T&D's Cloud system from computers, tablets, and smartphones.
Q: Can alerts be set up?
A: Email alerts can be set up when temperature, humidity, or other defined values exceed limits.
Q: How does the RTR-574 differ from other data loggers?
A: The RTR-574 can simultaneously measure four values: light, UV, temperature, and humidity, calculate accumulated light values, and support data upload to the Cloud. This makes it ideal for conservation and environmental control applications.
Summary
The case study of the Saint Louis Art Museum demonstrates that using the T&D RTR-574 Wireless Data Logger provides more accurate and continuous monitoring of temperature, humidity, light, and UV radiation. This reduces the risk of artwork degradation and enhances the efficiency of conservation data management in the long term.
For organizations seeking a comprehensive Environmental Monitoring system that can measure, display, and alert, the RTR-574 is a solution that effectively addresses environmental care needs.
