How Does It Compare with the JLab Polygraph?
| Model | Pen system | Chart drive and paper | Transducers, couplers and accessories |
|---|---|---|---|
| Student Physiograph (EL-SP-2378) | Modular interchangeable pen motors; 120 mm ink pens; 70 Hz at -3 dB | Ten listed speeds, 0.05 to 50 mm/s; silent gear train; Z-fold paper | Pressure, volume, force, respiration, pulse and isotonic transducers, four couplers and EKG/EEG accessories listed |
| Polygraph | Modular interchangeable pen motors; 120 mm ink pens; 70 Hz at -3 dB | Silent gear train; Z-fold paper (speeds not listed) | Not listed in its specification |
Choose the student physiograph when you want a recorder specified with its transducers, couplers and electrode accessories for a complete teaching set-up; the polygraph listing describes the same type of pen and chart system without those items.
What Is a Student Physiograph Used For?
A physiograph turns physiological events into electrical signals through transducers or electrodes, amplifies them and writes each one as an ink trace on moving chart paper. In physiology and pharmacology practicals for medical, pharmacy, veterinary and life-science courses, this one can record arterial and venous pressure with the strain-gauge pressure transducer, small volume changes by plethysmography, contractions of heart and smooth-muscle preparations through the force and isotonic transducers, breathing with the respiration transducer and pulse with the photo-electric pulse transducer. The EKG limb and chest electrodes and the EEG electrodes, jelly and paste supplied in the accessory list let students take electrical recordings from the heart and brain in a teaching setting.
The ten chart speeds cover very different signals: slow speeds such as 0.05 or 0.1 mm/s suit long recordings like a blood-pressure trend through a drug experiment, while 25 and 50 mm/s are the speeds commonly used to spread out an EKG waveform. The 120 mm pens reduce the arc distortion that a shorter pen produces as it swings, at the cost of a 70 Hz (-3 dB) response, and the silent chart drive matters because a humming motor or gear train can act on the subject and appear as biofeedback in the recording. Z-fold paper lets you turn back through earlier sections of a long run.
What to Specify When Ordering
- Transducers and couplers — list the ones your practicals need (pressure, volume, force, isotonic, respiration, pulse) so the quotation states exactly what is included.
- Time and event channel — it is optional, so say whether you want it.
- Consumables — extra Z-fold chart paper, ink, EEG jelly and paste for a full term of practicals.
- Quantity and tender details — the minimum order is 10 units; add any tender reference.
Frequently Asked Questions
What chart speeds does the student physiograph offer?
Ten: 50, 25, 10, 5, 2, 1, 0.5, 0.25, 0.1 and 0.05 mm/s, selected on the chart drive in the horizontal section of the console.
Why does it use 120 mm pens?
A longer pen gives less arc distortion of the waveform. With the 120 mm ink pens the frequency response is 70 Hz at -3 dB; shorter 75 or 80 mm pens give an appreciably higher response but more arc distortion.
Which transducers can be used with it?
The listing names a strain-gauge pressure transducer using a Statham Model P23 (-30 to +300 mmHg), a strain-gauge volume transducer for plethysmography, a heart, smooth muscle, isotonic muscle and isometric force transducer, a respiration transducer, a photo-electric pulse transducer and an isotonic transducer. Confirm which are included in your quotation.
What accessories come with it?
The accessory list covers a set of 4 EKG limb electrodes with straps, 1 chest electrode, 8 EEG electrodes, 2 ink-writing pens, 2 pen cradles, 1/2 litre of ink, 2 ink-writing chart papers, a tube of EEG jelly, a jar of EEG paste, a 3-pin junction box and an earthing cord.
How many recording channels does it have?
The listing does not state a channel count. Tell JLab which signals you need to record at the same time and the configuration will be confirmed with the quote.
What should an export enquiry include?
The quantity, destination country and port or city, preferred delivery terms such as FOB or CIF, the transducers and options required, any packing or labelling needs and the tender reference if there is one.
Who supplies the student physiograph?
JLab (Jain Laboratory Instruments Pvt Ltd) of Ambala, India, supplies it and quotes for it directly.
Supplier
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a laboratory equipment company incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. It supplies this physiograph to schools, colleges, universities, dealers and importers alongside its own range of psychology, physiology and general laboratory apparatus, so a department can source the recorder and related teaching equipment through one enquiry.
