The Process Analytical Experts
- pH, ORP & Conductivity
We offer the broadest portfolio of innovative pH and conductivity sensor technologies, materials, sizes, and geometries in the business. From ultrapure water to the most aggressive acids and bases, we can handle your process solution.
Among our offerings are electrodeless conductivity, pH/ORP/ISE, flow-through conductivity, and contacting conductivity/resistivity sensors. Rely on Schneider Electric sensors to resolve your most challenging applications.
Our breadth of lines drastically simplifies your requirements for installation, calibration, accessibility, troubleshooting, and maintenance.
- Model 876 Family of Loop-Powered Electrochemical Transmitters
The Model 876 is a comprehensive yet simple family of transmitters for use with Schneider Electric’s wide range of electrochemical sensors. All members of the family are 2-wire loop-powered devices with galvanically isolated 4–20 mA analogue and HART digital signal outputs.
Calibration and configuration can be carried out using the local keypad/display interface, a HART handheld communicator, or a PC-based Field Device Tool (FDT) certified DTM (Device Type Manager). The 876 Family is certified intrinsically safe for hazardous location installations. All 876s offer continuous sensor/transmitter diagnostics.
The Model 876PH operates with either analogue or Smart (digital) pH, ORP, or combination pH/ORP sensors or with analogue ion-selective electrodes (ISEs). The Smart version, 876PH-S, has English, French, German, Italian, Spanish, Portuguese, and Russian language options and a backlit LCD indicator.
- Model 875 Family of Line-Powered E-Chem Analysers
Besides the analogue measurement capabilities of the 876 Family, the Models 875PH, 875CR, and 875EC offer additional features in a line-power-based instrument.
The 875 Family is offered in both panel- and field-mounted versions, all with a large backlit LCD display. 875 Analysers offer dual analogue outputs and optional HART digital.
Dual, configurable relay contacts are also provided as well as digital inputs that allow remote control of hold and application switching features. The 875CR has dual, individually configurable conductivity channels.
The Right Fit for Every Application
- From Pure Water to PH Measurements
Schneider Electric sensors provide the specific advantages for each required application:
- For Pure & Ultrapure Water Measurement
Our 871CR sensors supply the highest possible accuracy.
- For Aggressive Chemicals or Industries Requiring Unbroken Process Lines
Our flow-through 871FT sensors offer an innovative, non-invasive conductivity solution.
- For Ph Measurement in Aggressive Chemical Solutions
Our pH reference technology with internal Nafion™ ion barrier protects the external junction from fouling and reduces maintenance.
- High-Precision EP485 Resistance Calibration Plugs
Experience precise calibration with a shirt-pocket tool. Simplify the calibration of any Schneider Electric electrodeless conductivity sensor loop by using our high-precision EP485 resistance calibration plugs.
The pH Benchmark
Our PH10 sensor line has revolutionised the field with its NAFION ion-barrier reference technology, rugged plastic construction, and non-metallic solution ground. With remarkable longevity in the harshest environments and outstanding ease of use in any application, PH10 sensors have become the industry standard for pH/ORP sensors. These innovative features are also available in 12mm smart and analogue PH12 sensors.
Smart pH Measurement
Schneider Electric now offers a comprehensive portfolio of Smart pH and ORP measurement products. Smart sensors have integral electronics which process the analogue signals internally and communicate conditioned pH, ORP, and temperature readings digitally to a transmitter or PC.
Smart versions of PH10, PH12, and 876PH and a Smart pH PC Interface make up the Schneider Electric Smart pH portfolio. Smart pH sensors have internal, non-volatile memory, which contains factory data, such as date code and model number, calibration data, sensor history log, and diagnostic information.
Smart sensors can be calibrated by a skilled technician in a lab and later swapped into service at a measuring point where calibration data will be uploaded from the sensor to the transmitter.
With a Smart PH10 or PH12 sensor connected to a Smart 876PH, advanced features such as Sensor Service Prediction are enabled. Sensor Service Prediction uses calibration data and event timestamps in the sensor’s history log to predict when maintenance such as cleaning or replacement will be required.
