Portable optical dissolved oxygen meter with automatic salinity compensation, 500 data logs, and USB output for reliable environmental monitoring.
The DO8500 Portable Optical Dissolved Oxygen Meter features a state-of-the-art luminescent optical sensor designed for precise and reliable measurement of dissolved oxygen (DO) essential in environmental analysis, bioprocessing, and molecular diagnostics.
Key technical features include:
This meter is widely used in live-cell imaging studies, environmental monitoring, and industrial biotechnology, offering critical dissolved oxygen quantification widely adopted in synthetic biology research and molecular cloning workflows. Its portability and ease of use make it a preferred instrument for researchers and laboratory professionals requiring precise DO measurements in both field and controlled settings.
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.
