Fluke 1620A-H-156 DewK Thermo-Hygrometer

The Fluke 1620A-H-156 DewK Thermo-Hygrometer is a high-accuracy, precision instrument designed to measure temperature and humidity. It is one of the most accurate temperature and humidity graphical data loggers available on the market. The Fluke 1620A-H-156 measures temperature to ±0.125 °C and humidity to ±1.5% on two channels, displaying the data on a large, clear screen.

Key Features

The Fluke 1620A-H-156 DewK Thermo-Hygrometer has a range of features that make it a versatile and reliable tool for environmental monitoring. It has inputs for two sensors, each measuring both temperature and relative humidity, allowing it to monitor two locations simultaneously. The sensors are detachable, cable-extendable, interchangeable, and self-calibrating.

The Fluke 1620A-H-156 also has a large on-board memory, capable of storing up to 400,000 date and time-stamped data points.

The DewK Thermo-Hygrometer is network-enabled, featuring both Ethernet and wireless capabilities. Its built-in Ethernet RJ45 jack allows multiple DewKs to be monitored from the same screen using Log Ware III client-server software. This also allows for remote connectivity over the internet, enabling users to monitor critical conditions while away.

Advanced Calculations and Statistics

In addition to measuring temperature and humidity, the DewK Thermo-Hygrometer calculates dew point, heat index, and rates of change for both temperature and humidity. It also calculates a variety of other statistics, including minimum, maximum, and daily summary statistics, which are stored for the most recent sixty days.

Calibration and Traceability

All DewK Thermo-Hygrometer sensors come with NVLAP-accredited certificates of calibration for both temperature and humidity, complete with data and NIST traceability. This ensures the accuracy and reliability of the measurements, making the Fluke 1620A-H-156 suitable for use in calibration laboratories and other environments where precise measurements are crucial.
