Features:

• Isolated inputs for all channels enhance measurement safety by letting you record differing electric potential objects simultaneously
• Sturdy construction designed for use in the field.  Large, tough handle makes carrying a snap. Tough body and strong enclosure provide superior resistance to shocks, falls, and vibrations.
• High-speed printing for checking data right on the spot. Printer features newly designed roll paper drop-in loading and one-touch setup, along with high 50 mm/s printing speed.
• Ergonomic controls for superior user convenience. Large key tops are easy to operate and feature surface coating so you can simply wipe off grease stains and other residue.
• High-speed sampling up to 20MS/s with fully isolated inputs
• 16 analog + 16 logic channels to 64 logic + 10 analog channels
• Built-in LAN and USB interfaces
• Multi-channel X-Y recorder with electronic data log
• Supplied accessories: Instruction Manual (1), Measurement Guide (1), Application Disk (Wave Viewer , Communication Commands table) (1), Power cord (1), Input cord label (1), USB cable (1), Printer paper (1), Roll paper attachment (2)
• Options (sold separately):8966, 8969, 8967, 8972, 8968, 8973
  Note: Main unit 8847 cannot operate alone. You must install one or more optional input modules in the unit.
