  • 2-Wire Dual Channel Transmitter/Analyzer FLEXA

    The model FLXA 202 2-Wire Analyzer, one model of FLEXA® series, offers single or dual sensor measurement. The modular-designed analyzer offers 4 kinds of measurements – pH/ORP (oxidation-reduction potential), contacting conductivity (SC), inductive conductivity (ISC) or dissolved oxygen (DO) – with the respective sensor module. For dual sensor measurement, the combination of two same type sensor inputs – pH/ORP and pH/ORP (analog sensor only), SC and SC, and DO and DO –are available with two sensor modules. Dual sensor measurement offers additional functionalities; calculated data function and redundant system. Variety of calculated data from two measuring parameters is selectable for each measurement. On the redundant system built on two measuring parameters of two sensor inputs, the main output parameter is automatically switched over to the second sensor output in case of the main sensor’s failure condition. Addition to conventional analog pH/ORP sensors, the analyzer FLXA202 can be connected to Yokogawa’s digital sensor, FU20F / FU24F / SC25F Digital pH/ORP SENCOM® Sensor.

    In the FLXA202 Human Machine Interface (HMI), 2-wire type analyzer FLXA202 offers easy touch screen operation and simple menu structure in 12 languages. Menus of display, execution and setting are displayed in a selected language. The analyzer FLXA202 automatically recognizes the installed sensor module and prepares the necessary menus for right configuration, even for dual sensor measurement. For immediate measurement, the FLXA202 offers quick setup functionality. The quick setup screen appears when the analyzer is powered. Only a few setups – date/time, language, basic sensor configurations and output – will start the measurement.

    The FLXA202 offers the best accuracy in measurement with temperature compensation functionality and calibration functionality. Sensor diagnostics and sensor wellness indication make measurement reliable. Logbook of events and diagnostic data is a useful information source for maintenance.

    For the wide range of industrial environment, the FLXA202 is designed with the enclosure of aluminum alloy cast with corrosion-resistant coating.

  • EXAxt PH450 4-Wire Analyzer for pH and ORP

    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.

    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

  • PH87/PH97 Retractable pH and ORP Assemblies and Electrodes

    The PH97 electrodes are designed to be durable and rugged for use with the PH87 assemblies. Each PH97 holds four separate elements in a rugged Ryton™ body which includes a pH bulb guard and an anti-blowout restraint. This pH system is composed of a metal impregnated Ryton™ solution ground, a double-junction reference, universal pH glass (0-14 pH) and a PT1000 temperature element.. In many applications the large volume reference reservoir will provide an extended functional life.

    Optional ORP (± 5000 mV) or patented solid state reference electrodes with a unique ionic trapping system are available for specialized applications.


    The Model PH87 assemblies are constructed of chemically-resistant titanium sheathes and are used with Model PH97 sensors. The retractable assembly is suitable for “Hot-Tap” service and is removable from a pressurized process line or vessel without interrupting the flow or draining the tank. The insertion assembly is suitable for service in a process line or tank where variable insertion lenghts are required. Blowout protection is provided by the flared tip design of the titanium sheath which provides a metal to metal stop during retraction. Integral junction boxes are provided for simple installation and wiring.
