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 pH2400 is a glass electrode with 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)
• Maximum chemical compatibility: glass electrode bodies are inert to most reactions
• Extended lifetime: Refillable reference junction allows sensor maintenance, saving replacement costs
• Great for wet or corrosive environments: BNC boot protects meter connection
• Compatible with any meter accepting BNC
• Instantly ready for use: Shipped in storage bottle for long shelf life – guaranteed for one year
• One year limited warranty: We stand behind all our products with the Sensorex Guarantee
