Fluke 1620A-S-156 DewK Thermo-Hygrometer

Fluke 1620A-S-156 DewK Thermo-Hygrometer

The Fluke 1620A-S-156 DewK Thermo-Hygrometer is a state-of-the-art instrument designed to measure temperature and humidity with high precision. It is one of the most accurate temperature and humidity graphical data loggers available in the market. This device is equipped with two channels that display measurements on a large, clear screen, making it easy for users to read and interpret data.

Key Features

The Fluke 1620A-S-156 DewK Thermo-Hygrometer boasts superior accuracy, with the standard-accuracy sensor (“S” model) reading temperature to ±0.25 °C over its calibrated range of 15 °C to 35 °C. Relative humidity readings are to ±2% RH from 20% RH to 70% RH. All DewK sensors come with NVLAP accredited certificates of calibration for both temperature and humidity, complete with data and NIST traceability.

The network-enabled device allows users to connect multiple DewKs via Ethernet, wireless (optional), or RS-232. The Log Ware III software allows real-time logging of multiple DewKs, data storage to your computer, and seamless integration with MET/CAL® software.

Additional Specifications

The Fluke 1620A-S-156 DewK Thermo-Hygrometer is designed for versatility and convenience. It can be wall-mounted or set on a bench top, depending on the user’s preference. It operates on a 12V DC power supply, sourced from an external 100 to 240V DC power supply. A standard 9V battery backup enables continued measuring during power disruptions. The device is compact, with the sensor measuring 3.1 x 0.75 inches and the DewK measuring 4.9 x 8.3 x 2 inches. The device weighs 1.5 lbs.

Advanced Capabilities

In addition to temperature and humidity, the DewK calculates dew point, heat index, and rates of change for both temperature and humidity. Minimum, maximum, and a variety of other statistics are also calculated and can be shown on-screen. Daily summary statistics, including minimum, maximum, and maximum rates of change are stored for the most recent sixty days.
