  • Applications: EEG, ECG, EMG, plethysmography, and respiration waveform measurement
  • Input: DC INPUT terminal with USE DC INPUT V/cm panel indication
  • Sensitivity: Approximately 0.05–10 mV/cm, selectable
  • Low-cut filtering: Selectable time constant of approximately 0.03–0.3 sec
  • Controls: CAL switch and DC/OFF switch
  • Format: Rack-mounted plug-in module
  • Configuration: Can be used with other channel units for multi-point physiological signal acquisition

This used Nihon Kohden AB-631G amplifier module is supplied as the main unit only. The power supply, connection cables, probes, and other accessories are not included. The unit is sold as-is and may show external scratches or surface contamination. Because the internal circuit board forms an integrated assembly, electrostatic discharge protection and secure connector fastening are recommended during installation.

Why Questpair exists

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.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
