Chemical Resistant Liquid Crystal Polymer (LCP) Body
Up to 914 m (3000 ft.) Transmission Distance SPECIFICATIONS PHE-6028-PO Differential pH Sensor
The PHCN-670 Series has been discontinued. Please see the PHCN-961/962 Series as a possible alternative or contact our Flow Engineering department.
The PHCN-674 1 /4 DIN panel mounted or the PHCN-675 and PHCN-676 1 /2 DIN panel or surface mounted pH analyzers are powerful but easy to use. They accept many different types of pH or ORP electrodes including the special PHE-6028-PO preamplified differential sensor. The units feature multiple language capability in English, French, German or Spanish and menu screens which guide you through setup, calibration, operation and test maintenance functions. pH DIFFERENTIAL SENSOR TECHNOLOGY The unique differential sensor technology offers many advantages over conventional sensor technology. It uses three measuring electrodes instead of the two contained in conventional pH sensors. The process electrode and standard electrode measure the pH differentially with respect to a third ground electrode. This technique is proven to provide unsurpassed accuracy, reduce reference junction fouling, and virtually eliminate ground loops. The benefit is greater reliability with less downtime and maintenance. The differential sensor, with its built-in preamplifier, boosts the high impedance mV signals of the electrodes, providing a strong signal which can be transmitted up to 914 m (3000 feet).
