METTLER-TOLEDO SEVEN2GO PRO S9-METER portable oximeter with optical sensing, ISM probe compatibility and pressure compensation.
The METTLER-TOLEDO SEVEN2GO PRO S9-METER portable oximeter measures dissolved oxygen for biotechnology and life sciences laboratories. It uses optical sensing and automatic pressure compensation.
The unit is compatible with ISM probes and supports automatic probe data detection and recording. Digital connectivity is available. The probe is not included.
The unit is used and remains in its original packaging. Its operating temperature range is 0 to 50 degrees C.
The METTLER-TOLEDO SEVEN2GO PRO S9-METER is a portable dissolved oxygen meter for oxygen measurement in biotechnology and life sciences laboratories. Its optical sensor supports oxygen measurement without the probe included in this configuration.
The used unit is supplied in its original packaging. The probe is not included.
The oxygen accuracy changes across the measurement range. It is ±0.1 mg/L from 0 to 8 mg/L and ±0.2 mg/L from 8 to 20 mg/L. This distinguishes the stated precision for lower and higher dissolved oxygen concentrations.
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.
