Electronic Development Laboratories, Inc.


EDL’s Nervo-Scope® has been the industry standard in Chiropractic thermal detection since it hit the market in the early 1950’s. The current ETS-9 and ETS-9A (the Analagraph® compatible version) are the  result of constant refinement and improvement - and still remain the most sought after Chiropractic scopes available. The Nervo-Scope® is used to reliably detect and measure miniscule heat differentiations in the tissues along the spine. The scope is used comfortably for both pre and post adjustment assessment. This newest iteration of the long time trusted scope was developed to provide accurate readings in a world full of RF interference from cell phones, iPads and tablets, laptops, even fluorescent lights. The ETS was developed to reject the influence of these sources and consistently give precise and repeatable readings each and every time the instrument is used. All Nervo-Scopes® are hand-made by skilled craftsmen in our Virginia facility. In addition to manufacturing new scopes, we are committed to providing ongoing service on every scope we ever produced. At EDL – there is a time honored tradition of building a quality product, listening to the Chiropractic community, and developing products based on its’ needs. This scope may be used alone or with the Wireless Analagraph®. With the Nervo-Scope® and Wireless Analagraph®, both patient and Doctor are able to see the spine, and where the subluxations are located.

The Nervo-Scope® ETS Series- 

Thermal Detection Instruments for Chiropractic Professionals

Nervo-Scope® is used by professionals around the world to reliably detect and measure minute heat differences in the tissues along the spine. This instrument may be used comfortably on children, adults and even animals for both pre and post adjustment assessment. Trusted by industry professionals since the 1950's - we are the original scope manufacturer. 

Nervo-Scope® is built to withstand the rigors of continual cleaning and disinfecting. We recommend using only an EDL approved cleaner. A large meter scale with a fluorescent pointer makes even the smallest temperature change easy to read. The sensing detectors can be adjusted from 0.6” wide to 2.1” wide to accommodate infants and adults.
