Physograph

Product Description

Physograph

Features:

• Unique system of pen motors, Modular easily interchangeable in a minute or two.
• Pen length standard 120mm for ink writing system improving upon the international standard (100mm) as per Grass or BECKMAN,
• Shorter pen length would mean greater arc distortions which is synonymous with wave form distortion and arc distortion. Pen length below 100min is not internationally accepted,
• Frequency Response: with 120min ink pen length 70Hz-3db. With shorter ink pens 75 or 80min length this response will he appreciably higher.
• Chart Drive - With completely silent gear train fitted with finest imported synchronous motor free from any backlash. Noisy or large humming gear train or motor can introduce Bio-feedback signals.
• Z fold chart paper for easy back reference and recording,
• Ripple free power supply with high stabilization and overload protection.
• Modular Time & Event channel (optional).

Console:

The Horizontal section houses the 10 speed Chart Drive, Galvanometers (Modular) with stabilized ripple free power supply & the vertical section housing the amplifiers and with ink pens and inkwell assembly.
