Student Physiograph - Modular Pen Motor System | 120mm Ink Writing Length, 70hz Frequency Response, Silent Gear Drive, Z-fold Chart Paper, Strain Gauge Pressure Transducer

Student Physiograph

SALIENT FEATURES:
1. Unique system of pen motors, Modular easily interchangeable in a minute or two.
2. 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,
3. FREQUENCY RESPONSE: with 120min ink pen length 70Hz-3db. With shorter ink pens 75 or 80min length this response will he appreciably higher.
4. 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.
5. Z fold chart paper for easy back reference and recording,
6. Ripple free power supply with high stabilization and overload protection.
7. 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.
Ten Chart Speeds provided are -50, 25, 10, 5, 2, 1, 0.5, 0.25, 0.1, 0.05 mm/sec.
TRANSDUCERS:
1. Pressure Transducer : Strain Guage Using STATHAM MODEL P23 a range -30 to +300 mm/ Hg. sufficient over pressure protection.
APPLICATIONS : Arterial and Venous pressure.
