Introduction
The 1620A DewK Thermo-Hygrometer is an advanced environmental monitoring device designed for calibration labs. It offers enhanced features over its predecessor, the 1620 DewK, including Ethernet and wireless connectivity, and upgraded LogWare III software for real-time condition monitoring and alerts.

Specifications

• Accuracy: Two sensor models are available: the high-accuracy "H" model with temperature accuracy of ±0.125 °C and RH accuracy of ±1.5 %RH, and the standard-accuracy "S" model with temperature accuracy of ±0.25 °C and RH accuracy of ±2 %RH.
• Operating Range: 0 °C to 50 °C and 0 %RH to 100 %RH.
• Memory: Stores up to 400,000 date- and time-stamped data points.
• Display: 240 x 128 graphics monochrome LCD with customizable display setups.
• Connectivity: Ethernet, RS-232, and optional RF wireless capability.

Features

• Calibrated Sensors: Each DewK can monitor two locations simultaneously with interchangeable sensors that store calibration data internally.
• Alarms and Battery Backup: Visual and audible alarms for various conditions, with a backup battery for up to 16 hours of operation during power failures.
• Data Analysis: Calculates dew point, heat index, and rates of change for temperature and humidity. Daily summary statistics are stored for 60 days.

LogWare III Software
LogWare III enhances the DewK's capabilities by allowing remote monitoring and logging of multiple devices. It supports customizable alarms, security features, and data export options. The software also facilitates "hot-swapping" of sensors without interrupting data logging.

Models and Accessories
The DewK is available in various models with different accuracy levels and accessories, including spare sensors, wireless modems, and protective cases. LogWare III software licenses are available for single or multiple users.

Conclusion
The 1620A DewK Thermo-Hygrometer by Fluke's Hart Scientific Division offers superior accuracy, extensive connectivity options, and powerful data logging and analysis tools, making it an ideal choice for precise environmental monitoring in calibration labs.
