Thermo Fisher, PH21A1A2, DataStick CPVC Differential pH Sensor Head

Unit Size: Each
• The pH sensor is of Differential Electrode Technique design, using two electrodes to compare the process value to a stable internal reference standard buffer solution. The standard electrode has non-flowing and fouling-resistant characteristics.
• Hex-shaped wrench flats facilitate mounting, and are constructed of a material that exhibits exceptional chemical resistance and mechanical strength. This material enables the sensor to be installed in metal fittings without leakage usually caused by heating and cooling cycles when dissimilar materials are threaded together.
• The sensor has interchangeable, pre-calibrated plug-in sensor heads and communications adapters that can be installed without powering down the system.
• The sensor has 1 inch NPT threads to mount into a standard 1 inch pipe tee, a 1.5 inch union mounting, or immersion hardware.
• The built-in electronics of the sensor are completely encapsulated and O-ring sealed for protection from moisture and humidity.
• The sensor has a built-in pre-amplifier, universal signal conditioning electronics, universal engineering units conversion, and interactive communications with a host computer or display interface using one of several protocols including ModbusTM RTU, Ethernet or USB.
• The sensor has an integral temperature sensor to automatically compensate measured values for changes in process temperature.
• The sensor includes a titanium ground electrode (standard) to eliminate ground loop currents in the measuring electrode
