2635A/C Hydra Data Bucket
The ideal choice for gathering and transporting large volumes of data and for working extended periods from remote locations.

Flexibility
The Hydra Data Bucket comes equipped with a 1 MB PCMCIA card and is also available with a 4 MB memory card to suit your data storage needs. Data may be uploaded from these cards via the Hydra RS-232 port.  Real-time data can be simultaneously transferred to a PC at the same time it is recorded to the memory card.

Quick setups
Simply push a few front panel buttons or load instrument setups from the memory card.

Fail-safe features
The Hydra Data Bucket gives advance indication of a low battery or low memory condition on the memory card. Its internal memory buffer continues to store up to 70 scans while the card is removed.

Easy-to-use front-end
An RS-232 serial interface makes it easy to connect the Hydra to a PC or modem for real-time data acquisition in system style applications. 

Universal Input Module
The removable Universal Input Module enables fast, convenient set-up and reconfiguration. Any combination of dc voltage, ac voltage, thermocouple, RTD, resistance, or frequency measurements can be connected to the input module without the need for additional signal conditioning. Thermocouple reference junction compensation is automatically performed by sensing the temperature of the input module's isothermal block. For applications with multiple measurement locations, purchasing additional input modules provides the ability to quickly connect and disconnect a Hydra to these various sites while leaving all sensor wiring intact.

Data collection
Portable operation
The 2635A/C Hydra Data Bucket has been designed for applications where data is gathered in a stand-alone manner "on location" and later uploaded to a PC for analysis and/or archiving. Two models of the Hydra Data Bucket are available with PC memory cards ranging in size from 1 Mb or 4Mb in size.  For applications where large amounts of data are generated, you may swap memory cards without interrupting the Data Bucket's scanning.

Hydra Logger software
Hydra Logger
The Hydra Logger software package gives you a powerful data acquisition system when combined with a Hydra instrument and your PC. Hydra Logger gives you control of Hydra's powerful functions, including scanning, signal conditioning, sensor linearization, alarm detection and reporting, non-volatile data memory.  

Current measurements
AC or dc current measurements may be accomplished using either 2620A-101 current shunts or external current probes. Using Mx+B scaling provides direct readings in amps. For lower current levels, shunts may be located in the input module.
