  • Sealed Ag-AgCl Reference, Epoxy Epoxy plastic body incorporates glass electrode and sealed Ag-AgCl reference electrode in a single stem Range pH 0 to 14, 0° to 100°C Usable at pressures from 0 to 100 psig (690 kPa) Offered in choice of types, each with US Standard or…

  • The pH2000 has a double junction reference design to prevent reference fouling by heavy metals and other sample contaminants, low maintenance sealed gel reference design, durable Ultem® body.

  • Flat measurement tip for surface measurements and slurries, double junction electrode design prevents reference contamination, durable Ultem® body, booted BNC protects meter connection.

  • Surfaces like paper, leather, electrophoresis gels and agar plates may be difficult to measure with traditional pH glass bulbs due to concerns about breakage. A flat electrode like our pH2100, is ideally suited for these types of pH measurements as well as measurements of suspended sludges and…

  • 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…

  • Our pH2400 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.

  • If you deal with a wide variety of chemicals or any aggressive substances, a glass probe like our pH1400 is a safe choice due to the chemically inert properties of glass. This single junction electrode has a refillable reference cell.

  • pH Pre-Amplifier

    Sensorex

    Allows pH signal to be carried up to 1,000 feet Boosts signals of aging electrodes, providing readable, measurable results Interfaces with most pH meters Battery operated This pre-amplifier works with most pH meters, controllers and data acquisition systems. Input and output…

  • The pH3000 is specially designed to respond quickly and accurately to rapid temperature changes. The double junction reference design prevents contamination, allowing pH testing in samples containing heavy metals, proteins and enzymes, or TRIS buffer.

  • 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…

  • Sensorex 3-in-1 combination electrodes are excellent choices for applications requiring pH, reference, and automatic temperature compensation (ATC). The 3-in-1 electrode operates like three separate electrodes, at a value price, you would pay for only one electrode. These electrodes are…

  • Whether you need to measure pH in your swimming pool, aquarium, or hydroponics garden, you need a probe that will deliver accurate measurements day in and day out. Our pH1000 polycarbonate pH sensor provides reliable, stable readings in a range of environments, from greenhouses…

  • Our S272 series of pH sensors deliver reliable online pH monitoring for in-line or submersion installation configuration. Extended sensor lifetime with double-junction technology. Minimal maintenance required due to flat glass measurement surface. A versatile sensor for moderate and multi-purpose…

  • Output Modules for Sensorex S8000 Modular pH sensors, this Modbus pH transmitter module requires Electrode adapter EA899 or EA891. Use with S856 cable.

  • Durable and chemically compatible Ultem® or body, reliable and accurate over the full range of pH measurements, no refilling or maintenance required with sealed gel-filled design, instantly ready for use.

  • The research grade pH3400 is a highly versatile combination pH electrode, specially designed to respond quickly and accurately to rapid temperature changes.

  • pH2200 spear tip pH sensor, specially designed to penetrate semi-solid surfaces for effective pH measurement. Assembled with a bio-friendly Ultem® body, making it safe for use in food and soil. Use with any pH meter accepting a BNC connector.
