Used Nihon Kohden AA-601H coupler amplifier for respiration and plethysmographic signal measurement.
The Nihon Kohden AA-601H Coupler Amplifier Module is a used analog signal amplification module designed for integration into biological signal measurement systems. It is inserted into a compatible rack or dedicated main unit and receives power and operating control from the host system.
The front panel provides adjustment of amplification sensitivity and signal-processing parameters, allowing researchers to observe low-level analog signals. This physiological signal amplifier module may be suitable as a replacement or supplementary unit for research and education workflows involving biomedical instrumentation and bioelectric signal analysis.
This is a used, as-is unit with possible exterior scratches. Its performance and functionality may not match the original new-product specifications.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
