In laboratory environments such as medical, biological, and materials science research groups, samples and test conditions are constantly changing, but accuracy is always critical. The SG1041CD/BNC is a highly versatile combination pH electrode, specially designed to respond quickly and accurately to rapid temperature changes. The high sensitivity internals allow testing of low ionic samples. Safely measure samples containing heavy metals, TRIS buffer, or proteins thanks to the double junction reference design, which prevents fouling. Even test highly reactive chemicals: with a glass body, the SG1041CD/BNC is inert to a wide range of chemical reactions. High accuracy, temperature responsive measurements (pH 0-14) Chemically inert glass body Double junction reference prevents contamination

Applications such as environmental and wastewater sampling involve some uncertainty about what samples may contain. When dealing with unknown or unpredictable sample types, you need a pH probe you can trust to deliver accurate measurements regardless of the contaminants you encounter. The S200CD/BNC has a double junction reference design to prevent reference fouling by heavy metals and other sample contaminants. When you travel to remote sites to collect data, it is especially important that obtaining the measurements you need is hassle free. The S200CD/BNC features an Ultem® body and a BNC meter connection for durability you can trust in the field.

Agar plates, skin, and electrophoresis gels are all surfaces that may be difficult to measure with a typical glass bulb electrode due to concerns about bulb breakage. To facilitate these and other surface measurements, we created the S350CD/BNC flat tip pH electrode. It has a rugged flat measurement surface, which breaks less easily when it comes in contact with hard materials. This makes it a great choice for measuring slurries, sludges, and viscous samples as well as those containing suspended solids.

Environmental, wastewater, and other sampling applications may expose electrodes to unknown contaminants. Over time, exposure to contaminants such as heavy metals and reactive chemicals, will take a toll on a sensor’s functional components.  The best sensors for these types of applications are built to safely handle contaminants to maximize working lifetime. Our SG200C/BNC has a double junction reference design to prevent fouling by sample contaminants that interact with Silver (Ag). The refillable reference junction allows users to replace the liquid fill solution as it becomes depleted or contaminated, instead of replacing the whole sensor. Accurate measurements across full pH scale (0-14) Glass electrode body provides maximum chemical compatability Double junction design prevents r
