Benchtop pH meter for pH, ORP, and temperature measurements with USB, RS-232, and 1,000-record storage.
The Thermo Scientific Orion Star A211 is a benchtop pH meter for precise measurement of pH, oxidation-reduction potential (ORP), and temperature. It is suited to laboratory water analysis, environmental monitoring, chemistry, biology, and biotechnology workflows requiring reliable electrochemical measurements.
The Orion Star A211 pH meter provides an intuitive menu structure, multiple calibration options, and reproducible results for routine laboratory measurements. Its benchtop format and data-logging capability support applications in environmental testing, aqueous chemistry, biological research, and molecular biology laboratories.
The unit is described as being in very good condition, tested, and fully functional. The display is clear and free of pixel defects, and the keys respond precisely. An electrode stand and power adapter are included. A pH electrode may be included depending on the specific shipment scope.
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.
