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.)
