Fluke 2638A Hydra Series III Data Acquisition System

Fluke Corporation has introduced the 2638A Hydra Series III, its most recent addition to the Hydra line of data acquisition systems/digital multimeters. It features a full-colour display with easy-to-use menu system, DC measurement accuracy of 0.0024%, 6.5-digit DMM mode and CAT II safety ratings.

The 2638A incorporates the Fluke Universal Input Connector that supports 15 common thermocouple types and delivers thermocouple accuracy of 0.5°C. The plug-in universal input connector has 22 channels of differential analog input (expandable to 66) for wiring multichannel systems. Once wired, the connector can be disconnected and the 2638A moved and connected to another input connector, eliminating the need to disconnect and rewire test set-ups.

Selectable measurement input types include DC voltage, AC voltage, resistance, thermocouple, RTD, thermistor, frequency, and DC and AC current.

The Hydra Series III has 20 onboard maths channels with alarm settings for even complex maths calculations that record results to data files during each scan. It can chart real-time data of up to four channels at once with a history mode that allows scrolling through previously collected data without a PC or charting programs.

The Hydra Series III has onboard memory for storing more than 57,000 data records and configuration files, as well as a USB port to collect and store large files directly to a USB drive. The USB and LAN interfaces allow easy connection to PCs and networks.
