Fluke 2638A
Hydra Series III
Data Acquisition System/
Digital Multimeter
Price-performance break-
through in a stand-alone
data acquisition system
The Fluke Hydra Series III continues the
Hydra Series legacy of precision, multi-
channel data acquisition. The new Series
III improves on Hydra’s industry-leading
thermocouple accuracy and adds a new
dimension to how you collect and view data
in a portable system.
DC measurement accuracy of 0.0024 %, basic 0.5 °C thermo-
couple accuracy, full-color display, easy-to-use menu system
and industrial safety ratings put the 2638A in a category of its
own as a precision data acquisition system. The dedicated 6.5
digit digital multimeter (DMM) mode provides additional utility
and value.
The 2638A is expandable from 22 to 66 channels of dif-
ferential analog inputs. A flexible, 22-channel Universal Input
Connector lets you connect and disconnect any type of input to
any channel, quickly and easily. Selectable inputs include dc
voltage, ac voltage, resistance, thermocouple, RTD, thermistor,
frequency and dc and ac current. You can also use the 2638A
with optional software and other Fluke data loggers to create
a flexible, customized data acquisition system with an almost
unlimited number of input channels.
