The Extech 42280A-NIST Temperature and Humidity Data Logger is a versatile instrument designed for continuous monitoring of temperature and humidity in various environments. This data logger is specifically designed to help maintain ideal storage conditions in laboratories and cleanrooms, as well as ensure comfort in hospitals and other indoor working facilities.The Extech 42280A data logger is capable of continuously monitoring temperature and humidity, providing real-time information about the environmental conditions. This allows users to proactively manage and adjust the conditions to maintain optimal storage conditions or ensure comfort for occupants.With its max/min mode, the data logger can record up to 24,000 data sets, including the date and time stamp. This extensive data collection capability enables users to capture and analyze a significant amount of temperature and humidity data over an extended period.The data logger is equipped with both audible and visible alarms, which can be set to specific thresholds for temperature and humidity. These alarms serve as an alert system, notifying users when the measured values go beyond the desired range. This feature helps prevent potential issues by enabling timely intervention.The Extech 42280A data logger offers convenient reporting options. Users can generate PDF reports that include trending graphs, providing a visual representation of the temperature and humidity data over time. Additionally, the data can be exported to a Microsoft Excel spreadsheet, allowing for further analysis, data manipulation, and customization.By analyzing the data and observing the trends, users can easily identify irregularities or deviations in the environmental conditions. This helps in troubleshooting, identifying potential areas of concern, and taking appropriate corrective actions. It includes NIST Certification.
