Fluke 2635A, Fluke 2625A, Fluke 2620A / Fluke HYDRA - Prenosný záznamník dát

All models are easy to set up and reconfigure from the front panel. Additionally, all units have bi-directional communication via RS-232C, which enables control from a host computer. The RS-232C interface also supports stand-alone use with a serial printer. An optional GPIB/IEEE-488 interface is available for the 2620A only.

The Hydra Series isextremely rugged and able to operate in diverse environments. Its operating range is 0 to 60ºC, and it is tested to stringent shock and vibration standards. Hydra"s sturdy metal chassis effectively shields against electromagnetic interference, maintaining high measurement accuracy on low level signals. The analog circuitry is also isolated from the digital circuitry so you can measure high voltages directly (up to 300V ac rms). And it conforms to I.E.C., C.E. and CSA safety standards. What"s more, all set-up information is battery-backed, so it"s immune to power failure. Hydra will return from a power loss and resume scanning, while all configuration information and stored data remain intact.

Hydra Series Portable DataAcquisition

The Hydra Series offers easy portability along with Fluke"s built-in signal conditioning and Universal Input Module, at a price to fit your budget. You can easily retrieve data from the Hydra units via the RS-232 interface, or through a modem in upload or real-time mode.

Channel information and measurement parameters can be set up directly from the front panel or your PC.

Three models featuring removable memory card data storage, internal memory storage, and direct real-time data transfer options.

Should power fail, these instruments automatically resume data collection when power is restored.
