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. The 2638A is expandable from 22 to 66 channels of differential 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.
With DC measurement accuracy of 0.0024 %, basic 0.5 °C thermocouple 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.
If you need to “zero” a large number of thermocouples to a known reference temperature before starting a temperature profiling or validation test, the 2638A will normalize all readings to your reference channel at the push of a button and store the offsets for reference in a supporting data file.
