ORP Analyzers

Liquid analyzers are used for monitoring process chemistry including water quality, providing process optimization and control. Common measurements include pH, ORP, conductivity, resistivity, percent concentration, and dissolved oxygen.

Featured Solutions

  • 2-Wire Dual Channel Transmitter/Analyzer FLEXA

    The model FLEXA® 202 two-wire analyzer is used for continuous on-line measurements in industrial applications. It offers an option for a single or dual sensor measurement, making it the most flexible 2-wire analyzer available. The model FLEXA® modular-designed series analyzer offers 4 parameter choices – pH/ORP (oxidation-reduction potential), contacting conductivity (SC), inductive conductivity (ISC) or dissolved oxygen (DO) – with the respective sensor module.

    The FLEXA™ series analyzers are modular-designed analyzers used for continuous online measurements in industrial installations. They offer single or dual sensor measurement, making them the most flexible 2-wire analyzer available. With the FLXA202, there is no need for multiple analyzers, since it is easily scalable at the site location by swapping the internal measurement module to what is needed, giving you more flexibility and optimizing your OPEX.

  • PH450

    The PH450 provides the best pH measurement accuracy in the industry resulting from advanced temperature compensation functionality, preloaded calibration standards, stability checks and online sensor and analyzer diagnostics to provide verifiable results. In addition to dynamic sensor checking, the PH450 offers a wash cycle function to assure trouble free and accurate analysis with a minimum of maintenance.

    This four-wire, multivariable analyzer combines pH with temperature and ORP (Redox) measurement, all of which can be utilized through the different output functions: two mA current outputs, four independent SPDT contact outputs, and HART. Dynamic sensor checking and wash cycle functions assure trouble free and accurate analysis with minimum maintenance.

    Unique Human Machine Interface

    The PH450 has a high-resolution, simple touchscreen menu structure with five language options, so information is clearly visible and easily accessible to the operator. Simply select the language of choice and on-screen instructions assure that the best configuration for the application is obtained.

    Ideal for Ultrapure Water Applications

    The PH450 offers self-diagnostics and process temperature compensation to provide accurate pH measurements in high purity water. One of these temperature compensation methods, the NEN6411 algorithm, takes into account the dissociation of water in strong acid and alkaline solutions, which is especially useful for pH measurement in Pure and Ultrapure water as found in Power Generation Water Chemistry.

    Additional Features

    • Capable of analyzing pH, ORP or rH and Temperature measurements at the same time with the same sensor
    • Full PID control possible for both acid and alkaline addition simultaneously
    • Dual High Impedance Capability, allowing for Differential pH/ORP measurements
    • Enhanced diagnostics, process trending graphics and on-screen logbooks for data storage
    • Two mA-outputs and four SPDT relay contacts with display indicators
    • Hart® Communications
    • FM Class 1, Div.2, Group ABCD, T6 for Ta-20 to 55°C
    • IP66/NEMA4X 1/2 DIN enclosure for Field Mounting and Panel Mounting
    • Three sets of preloaded pH buffer standards (NIST, US and DIN) cover most commonly used pH calibration practices
    • Supports many temperature compensation elements and sensor types
