4 mm refillable liquid-electrolyte pH microelectrode with integrated NTC temperature sensor.
The Mettler Toledo InLab 751-4mm is a pH combination microelectrode designed for accurate measurements in small sample volumes, narrow vessels, and viscous media. Its slim 4 mm shaft supports access to confined containers, while the integrated NTC temperature sensor enables automatic temperature compensation during measurement.
This laboratory pH electrode is suitable for research, industrial analysis, biotechnology workflows, and routine measurements where reliable pH and temperature-compensated results are required.
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.
