Student Physiograph
STUDENT PHYSIOGRAPH: An equipment from Bio Devices come to you with the backing of battery of the experienced, dedicated and devoted people, to ensure that it remains functional, hassle-free and an asset for you, for life. With the changing times and technology, system upgradation is a must in order to be with the Physiograph. Thereby, ensuring that with Student Physiograph, you always stay ahead.
Ease of Operation of STUDENT PHYSIOGRAPH:
Even a beginner can easily understand and operate the STUDENT PHYSIOGRAPH with just simple explanation. Controls are kept to be bare minimum, without sacrificing any function or sensitivity. Sensitivity has not been sacrificed in designing the STUDENT PHYSIOGRAPH. Sensitivities as high as 5 micro volts per mm are obtainable. Ruggedness is reliability, so essential for an instrument or system which would be used by different batches of students. Versatility through the use of couplers for recording of various parameters.
Concept of group experimentation with STUDENT PHYSIOGRAPH:
Group experimentation concept which permits more then one STUDENT PHYSIOGRAPH to be used independently or interconnected to each other for the same experiments set-up, or interchanged with each other to record from different experiment set-ups in the laboratory. The STUDENT PHYSIOGRAPH: is complete system design with couplers, matching Transducers & Pick-ups, and matching Electronics Stimulators with facility of synchronized event maker time maker.
