ELECTRONICS RESEARCH
AND PRODUCTION
---Out of Stock---
We are undergoing engineering updates, and doing some artificial intelligence research ( . ). Within a year or so we will once again be available for repairs or accessories, or to re-sell used equipment; in support of our thousands of past customers. New instruments may be available within 2 or 3 years.
The instruments shown may have a new appearance... performance and prices would be similar... We are considering combining the functions into a single instrument, which would be less expensive than the combined listed prices.
If you wish to go on our waiting list, simply tell us which instrument(s) you are interested in... do not send any payment... we will contact you before the next production cycle, to see if you are still interested.
Thank-You for your interest in Biofeedback.

EMG 4 Features — $429 currently out of stock
Four Sensitivity Settings — to work with the strongest
or weakest musclewave levels
--- sets a new standard in true hum rejection;
can be used on an electric blanket, at full sensitivity!
( this is accomplished by geometrically balancing
the electrode configuration; this cancels a time difference hum element
that is not otherwise reject-able with electronic common-mode rejection;
this also permits effective shielding of the electrodes for a further reduction
in hum pick-up)
Two Visual Feedback Modes — logarithmic meter and instantaneous LED for individual pulses
Three Audio Feedback Modes — direct EMG, pulsed EMG, and average-driven tone with threshold pitch step
Stabilized — with respect to varying room temperature and battery voltage so that measurements from one session to the next reflect true progress
Headphone Jack — silences built-in speaker
Accessories & Instructions Included — everything needed for use is included
Parts, Labor, and Specifications are Guaranteed for
5 Years
Optional A\B Input — selector switch and second input connector for instant comparison of two
electrode sites. $20 with unit, or $45 for returned unit
(Also order a matching second electrode set, below,
or below right.)
