Product Documentation


The Fluke 2620A, 2625A, 2635A Hydra Data Logger & Acquisition Units offer 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 Fluke Hydra units via the RS-232 interface or through a modem in upload or real-time mode. Channel information and measurement parameters can be setup directly from the front panel or your PC.

Features of  the Fluke 2620A, 2625A, 2635A:

  • Review the min/max and last readings from the front panel
  • Channel 0 accepts standard test leads from the front panel for quick measurements
  • Monitor a selected channel from the front panel
  • Use the Channel function to configure measurement type and range for each individual channel
  • Use the Memory Card Drive (in 2635A only) to store data and instrument configuration on a portable, non-volatile memory card and transfer collected data to your PC for later analysis
