STUDENT PHYSIOGRAPH is used for the recording of Bio-Electrical Potential e.g. EEG, ECG, ENG, EMG, Pulse, Respiration, Blood Pressure etc. It is made of light metal for compactness and lightness. Its performance is outstanding due to adoption of integrated circuits.
Each unit is so designed that a trouble free, simple and precise operation is possible. Appearance is very smart and compact for ease of carrying.
STYDENT PHYSIOGRAPH comprises of:
Accessories like electriode.
The main console houses
Ink Pen recording system
Housing for plug in couplers
Electronically controlled 9 chart speeds provided are .5,1,2,5,10,20,25,30 & 50 mm/sec. Any other speeds are provided against specific requirements.
Speed selection is easy and instantaneous.
Channel width is 70 mm
Ink writing pen is 120 mm in length to minimise arc distortion.
The main Amplifier is fitted in the console having switch selectable sensitivity range from 50 microvolts per cm to 100 millivolts per cm in eleven steps as 50,100,200,500 µv/cm and 1,2,5,10,20,50,100 mv/cm
Different couplers are designed to record different parameters. They are modular interchangeable in the same console or from console to console and one can easily plug them in or out in few seconds. The standard range of couplers is as follows:
For recording all AC phenomena like ECG, EEG, EMG,ENG etc. It is supplied with 3 pin junction box, EEG-EMG electrodes and paste etc.
For recording clinical ECG. It is supplied with 5 pin junction box, Limb & Chest electrodes and Jelly.
For recording from all straingage transducers and used to record muscle activity force, effect of drug on heart activity, Blood pressure from cannulated animals, volume changes etc
For recording pulse or respiratory activity using pulse, respiration Belt or respiration transducers.
For recording internal or surface temperature through transducers.
Using it along with isotonic fine movement transducer one can perform experiment on isolated uterus and isolated intestine
A Transducer is a device which converts one form of physical energy to electrical energy or vice versa. To record parameters which are not available in electrical form e.g. Pulse, Respiration, Temperature, Phono Cardiogramme etc., one needs to use appropriate transducer. We manufacture following transducers.
1.Pressure 2. volume 3. Muscle Activity/ Force. 3. Respiration Belt Isotonic Fine Movement. 4.Pulse . 5. Respiration (Thermistor). 6. Temperature Internal, 7. Temperature Surface,
