  • replacement probe for BNC meter
    When accuracy and repeatability are critical, such as in pharmaceutical or drinking water applications, the ideal electrode will quickly deliver stable measurements. The pH3000 is specially designed to respond quickly and accurately to rapid temperature changes. The high sensitivity internals also make these sensors the best choice for low ionic samples. The double junction reference design prevents contamination, allowing pH testing in samples containing heavy metals, proteins and enzymes, or TRIS buffer.
    • High sensitivity internals for temperature responsive measurements
    • Refillable reference for maximum measurement repeatability
    • Double junction design prevents reference contamination
    • Durable Ultem® body
    • Reinforced meter and cable connections
    • Removable pH glass guard

  • optical dissolved oxygen sensor

    Now Available with MODBUS/RS485 Interface & optional Titanium body

    The Lumin-S optical dissolved oxygen sensor delivers reliable DO measurements over a long operating life. There are no membranes to replace, no electrolyte solutions to replenish, and no anodes to clean. Maintaining the sensor is as easy as replacing the optical sensing cap once every 1-2 years, and since all calibration data is stored on the cap, there’s no need to calibrate. This dissolved oxygen sensor outputs a Modbus/RS-485 digital signal for easy PLC integration.
    • Reliable measurements: Optical sensor technology delivers accurate DO monitoring with no drift and no minimum flow
    • Long operating life with minimal maintenance: No membranes, electrolyte solutions, or anodes - just replace the cap once every 1-2 years
    • No calibration: All calibration data is stored on the cap for quick and easy startup
    • Simple system integration: Use Modbus/RS-485 to integrate with a PLC or other control system
    • One year limited warranty: We stand behind all our products with the Sensorex Guarantee

  • ORP probe for measuring ORP online
    Moderately contaminated water, such as industrial source water or natural water resources, may contain chemicals and debris that damage ORP probe components. Continuous monitoring in these types of applications requires a durable and low maintenance ORP probe. Our S272 series of ORP probes feature a double junction design to protect the reference cell from contamination by sample components that interact with silver. The flat measurement surface is self-cleaning and resists breakage, for minimal maintenance.
    • Reliable performance in demanding applications
    • Extended sensor lifetime
    • Versatile design for submersion or in-line mounting
    • One year limited warranty

  • inline pH probe

    S8300 Modular pH Sensor

    In heavily contaminated wastewater or chemical processing applications, an inline pH probe typically wears out fast. Constantly replacing an inline pH probe can feel like a waste of time and money. We created our modular, quick disconnect S8000 sensor packages for these types of heavy duty industrial applications. The sensor can be replaced in a few seconds with no tools or re-wiring required by swapping the S8000CD Quick Change Replacement Cartridge. Reuse the cable assembly and other mounting hardware for a low cost of ownership.
    • Recommended for challenging water and wastewater applications
    • Uses direct 4-20mA analog or MODBUS/RS485 digital output signal to integrate with a PLC or other control system
    • Fast sensor changes with no tools required
    • Reusable cable and mounting hardware
    • Low total cost of ownership
    • One year limited warranty
