Durable double-junction combination pH electrode with BNC connector for field, soil, and water testing
The Hanna HI 1230B is a combination pH electrode engineered for reliable pH measurements in various industrial, field, and general-purpose applications. Featuring a double-junction design, this electrode minimizes sample contamination, making it suitable for soil pH analysis and water quality monitoring in environmental and biotechnological research. The pH sensor is housed in a robust plastic (PEI) body with a gel-filled internal solution to enhance durability and extend electrode lifetime. Equipped with a 1-meter cable and a standard BNC connector, the device ensures easy integration with most pH meters. The protective tip design reduces breakage risk during direct immersion into soil or aqueous samples. This electrode is widely valued in molecular diagnostics, bioprocessing workflows, and environmental biotechnology studies for its resilience and precise pH detection capabilities critical in biopharmaceutical production pipelines. Alternative connector types are available upon request, supporting flexible setup in diverse laboratory and field environments.
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.
