Temperature Module

Vpl-bio-temp temperature modulethe vpl-bio-temp module is a versatile instrument which is specially designed to perform laboratory experiments and demonstration of temperature on human being. The module senses skin temperature which varies at different location on the body and with changing environmental demands.the system consists of various instrumentation and monitoring circuits which are easily understood by the students. Signals at various section in the circuit can be seen by using oscilloscope or pc recorder module.featuresuses thermistor to measure temperaturegain amplifieruses voltage controlled oscillator (lm566)frequency counter to display temperature in °c/°faccurate to 0.10°c centigrade/fahrenheitmeasures in centigrade/fahrenheit using selectable switchdirect digital readout on seven segment displaymeasures from 37°c to 99°cequipments suppliedtemperature probetemperature sheathlaboratory manualvpl-bio-gsr - galvanic skin resistance modulethe vpl-bio-gsr module is a versatile instrument which is specially designed to perform laboratory experiments and demonstration on gsr. The module senses the resistance changes on the palms of the hands, soles of the feet, surface of the skin.the system uses a constant current source passed through a changing skin tissue to generate a signal voltage. Changes in skin resistance are reflected as changes in signal voltage. The signal is amplified and then fed to a slight display and tone generator. The system consists of various instrumentation and monitoring circuits which are easily understood by the students. Signals at various sections can be sen by using oscilloscope or pc recorder module.featuresuses a constant current source (10µa)a bridge amplifierhigh gain amplifier (6000) approx.light bar indicator to display gsrglide tone circuitry to drive light bar indicationmodule capabilitymeasures gsr when touching the subject's hairclapping hands near the earcounting backwards in odd numbersequipments suppliedgsr electrodeslaboratory manualbiomedical disposal accessories package.
