Reliable device with auto/manual ranging, probe versatility, and precise measurement capabilities.
The Knick Laboratory Conductivity Meter 702 is in excellent technical condition, suitable for research professionals who require precise conductivity measurements. This versatile device supports both normal 2-electrode probes and Knick 4-electrode probes, granting flexibility in its application. Though it comes without a probe, compatible options can be conveniently sourced from the shop. The meter offers a wide range of measurements from 0.000 µS/cm to 2000 mS/cm with auto-ranging or manual settings. It also accepts temperature inputs from Pt 1000 and NTC 30 kΩ ranging from –50.0 to +150.0 °C and –20.0 to +120.0 °C respectively. Resolution is as fine as 0.001 µS/cm, with accuracy for conductivity at < 0.5% of the measured value ± 2 counts and for temperature at < 0.3 K. The device ensures reproducibility with < 0.1% of the measured value and offers a selectable admissible cell constant from 0.001 to 199.9 cm–1. Equipped with galvanically isolated recorder output, it supports multiple recording voltages for detailed data analysis.
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.
Yes. Every verified supplier states which service partners cover the instrument, and we list that 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.
