  • pH sensor refill solution
    Refillable glass pH electrodes contain liquid electrolyte solution, which serves to close the electrical circuit in a pH electrode. The electrolyte solution must have electrical contact with the solution being measured. Contact is made via a semipermeable junction, which permits a consistent outflow of liquid electrolyte.  Over time, electrolyte is depleted and should be replaced.

  • pH Detector
    The pH Detectors are designed for use with a variety of instrumental techniques such as FIA, HPLC and IEF and are also used to continuously monitor the pH of low volume flows in bench scale chemical systems. The pH detector system is specially designed to achieve ultra fast response times. A flat surface pH electrode (S450CD) located at the top of the flow cavity allows for very low internal volumes. The resulting rectangular cross-section flow path has no protruding parts which could interfere with a clean sweeping flow.
    • pH Detector system for HPLC, FIA, and IEF applications
    • Perfect for low volume flow measurements
    • Ultra fast response time
    • Flow cell and inlet/outlet fittings included

  • submersible orp electrode
    This submersible ORP electrode is ideal for tanks, flumes and sewer lines. The self-cleaning, flat-surface design makes the S651CD-ORP resistant to coating, increasing time between maintenance cycles. Protective feet guard sensing surface from breakage, and double junction reference protection extends the lifetime of the sensor. Should a replacement sensor be required, the S651CD-ORP is equipped with quick disconnect BNC connections to minimize downtime due to electrode maintenance. Designed for use with our S653 Cable Assembly for the S651CD for a complete Submersible Flat-Surface, Self-Cleaning ORP measurement solution.
    • Flat surface design resists coating
    • Double junction reference protection extends sensor lifetime
    • Use with our S653 Cable Assembly for quick and easy maintenance
    • Reliable CPVC construction
    • One year limited warranty

  • reliable combination pH electrode
    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 pH3400 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 pH3400 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
    • Refillable pump junction helps users easily extend sensor lifetime
    • Reinforced meter connection allows use in wet and corrosive environments
