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
