Tramex FBSK – Compact Data Logging Kit for Building and Material Moisture Monitoring
Professional-Grade Monitoring of Ambient and In-Situ Conditions
The Tramex FBSK kit is tailored for professionals who require precise, reliable measurements of relative humidity, temperature, dew point, and humidity ratio in buildings and building materials. It is especially suited for concrete and other substrates where ASTM F2170 compliance is necessary. The kit allows users to track environmental and on-site conditions in real time, ensuring quality control during construction, restoration, or inspection projects.
Praised for its accuracy, portability, and comprehensive logging capabilities, the FBSK stands out compared to other data loggers for building diagnostics. Its integration with the Tramex Meters App streamlines reporting, visualization, and analysis, which makes it highly valued by building inspectors, flooring specialists, and restoration professionals.
Wireless Data Logging and Visualization
The Tramex Feedback DataLogger can log up to 100,000 data points and transmits readings wirelessly via Bluetooth BLE to compatible iOS or Android devices. Using the Tramex Meters App, users can visualize live readings, thermal conditions, and psychrometric charts, as well as create, save, and export spreadsheets, charts, and comprehensive reports.
Standards Compliance and Ease of Use
The kit supports monitoring in accordance with BS 8201, BS 8203, BS 5325, and ASTM F2170. Instant setup and start modes, along with an intuitive app interface, allow for fast deployment on-site, reducing downtime and improving workflow efficiency.
Connectivity and Accessibility
With Bluetooth BLE connectivity up to 50 meters (165 ft), data downloads are highly accessible, even in large buildings or complex environments. The kit comes in a durable Tramex Easy-travel case, making it portable and protected for daily use on-site.
