PH450  4-wire pH/ORP Analyzer

The innovative PH450G 4-Wire pH/ORP Analyzer has a touch screen and is a reliable instrument with high functionality. It is used in medium-scale wastewater treatment and general pH measurement control applications in various industries. It has four contact outputs that can be used for diagnostics, wash routines, and alarm or PID controls.

With its unique human machine interface, the PH450G can display process, diagnostic, trend, and log data, and has eight language options. User-friendly step-by-step calibration routines are also provided that help improve quality. A sensor diagnostic function is included as a standard feature to ensure reliable pH measurements by detecting sensor failures. In addition, HART communication over an output current signal is enabled.

FLXA21 Modular 2-Wire pH/ORP Analyzer

The FLXA21 is a next-generation modular liquid analyzer that can be flexibly configured to measure pH/ORP, contacting conductivity, inductive conductivity, or dissolved oxygen. The FLXA21 also supports the installation of up to two sensors of the same type, thereby reducing installation costs and saving space in addition to enabling the configuration of a highly reliable backup system.

It has reliable and advanced features and functions such as a touch screen for improved operability, sensor self-diagnosis, maintenance time estimation, and 12 language display options.

PH202G, PH202S 2-Wire pH/ORP Analyzers (General/Explosionproof)

The PH202 pH/ORP Analyzer is designed for a 2-wire system configuration and is ideal for large-scale instrumentation. It can be used in hazardous areas and supports digital communications using the HART, Profibus-PA, or Fieldbus protocols.

The sensor diagnostics have been enhanced with the provision of an improved impedance check. Flexibility, low maintenance, and low installation costs are among the benefits of this analyzer. In addition to the sensor diagnostics, contact output for failure or wash can be used in combination with a dedicated distributor.

SC25F SENCOM sensor

SC25F SENCOM® digital sensor shows how Yokogawa applies the motto "Simply the Best" to sensor technology. Setup of the sensor is very easy because sensor specific characteristics such as calibration data are stored in the sensor automatically.

FU24F SENCOM Sensor

Processes in which sensors are subjected to pressure changes normally decrease the useful life time. The internal pressure compensation feature of the analogue is made available for customers using digital sensors in the FU24F sensor.


FU20F

FU20F SENCOM® digital sensor shows how Yokogawa applies the motto “Simply the Best” to sensor technology. Setup of the sensor is very easy because all sensor specific characteristics, such as calibration data, are stored in the sensor.

SPS24 SENCOM PC Software

The new SENCOM® PC Software SPS24 offers a unique means to optimize the performance of pH/ORP sensors for enhanced reliability and process safety. The software allows the operator to monitor pH/ORP sensor performance, calibrate and configure various parameters.
Simply connect your SENCOM® sensor via Interface Box and USB port to your PC and get access to intuitive analysis, sensor configuration, calibration information and documentation applications.

FU20 pH/ORP Combination Sensor

The FU20 comes with a single wide body sensor that can simultaneously measure pH, ORP, and temperature. The sensor body is constructed of durable Ryton and is resistant to shock.

The FU20 can be connected to an immersion pipe holder using an optional adapter, and is ideal for use in dirty water applications such as the treatment of human-waste, sewage, and wastewater.

PH8ERP/PH8EFP pH Sensor, OR8ERG/OR8EFG ORP Sensors

These pH and ORP sensors have a Ryton body that is highly resistant to corrosion, heat and mechanical shock, making them well suited for a wide range of applications. Both the glass electrode and junction can be easily replaced, significantly reducing costs.

These sensors can be mounted using flow-trough, immersion, or floating ball fittings, and optional water jet, brush, ultrasonic, and chemical cleaning devices are available.

PH8EHP pH Sensor for High Purity Water

The PH8EHP is designed for boiler and semiconductor process applications that rely on high purity water. A dedicated holder is available.

SM21/SR20/SC21 Industrial Elctrodes

The heart of a pH measuring loop is the electrode system. Yokogawa has designed a wide range of sensors to ensure this heart keeps beating under the most severe conditions.

Hamilton-pH-electrode
