Dual channel time period integrator for the J&J Stand alone M-57 sEMG and T-68 Temp GSR monitor. Can also be used with M53 or T63 by J&J.

See all our our USED products here.Two independent digital displays. Select Ch A or Ch B, average or percent time on either display. 12 integration periods - 1 second to over 30 minutes. Variable display allows a rest period between trials. Audio tones for both beginning and end of trials. No batteries required - powered from the connected instrument.

The D-200 Dual Digital Integrator quantifies the physiological activity monitored by the J&J stand alone biofeedback instrument. Two types of quantification are available: 1) a digital representation of the integrated absolute levels of the physiological activity, and 2) a percent time measure of the threshold activation. The dual display capabilities of the D-200 allow for the simultaneous quantification and display of two channels of physiological information. The range of time base periods allows one to quickly capture the variance of the physiological system during evaluations or to set up a "trials format" for biofeedback training. The delay mode on the D-200 facilitates a "trials format" by allowing for the rest period between trials. Using this function, a series of trials could proceed automatically.
