pH Sensor - 3200HP
The Rosemount Analytical Model 3200HPpH sensor isdesigned for the accurate measurement of pH in lowconductivity, high purity (HP) water. High purity waterapplications exist in the Power, Pharmaceutical, F&Band Semiconductor industries. Boilers, both industrialand at power plants also provide several points wherelow conductivity pH measurements are necessary. Thekey to an accurate measurement is a stable referenceelectrode that produces the same potential over manymonths of service whether in calibrating solutions orhigh purity water..

Model 3800 - 3800VP PUR-SENSE™ Autoclavable and Steam Sterilizable pH Sensors
Model 3800 - 3800VP PUR-SENSE™ Autoclavable and Steam Sterilizable pH Sensors

Designed for accuracy and stability in a heat intensive application, the new PUR-Sense™ 3800 series pH sensors are optimized for autoclaving and steam sterilization. Building on PERpH-X® and AccuGlass® technology, the 3800 sensors exhibit unparalleled stability after exposure to high temperature sterilization.

The 3800 series is available in three different insertion lengths, 120 mm, 225 mm and 325 mm. The 3800VP has a PT100 ohm RTD mounted inside the pH glass stem for automatic temperature compensation. The 3800 has no integral temperature sensor and is supplied with a coaxial S8 Pg 13.5 connector. .

pH/ORP Sensor - Disposable (399)
The reference junction aids in the sensor’s resistance to poisoning ions and helps prolong sensor life. Models 399 and 399VP are provided with a double junction reference, which protects the reference element from poisoning ions such as ammonia, chlorine, cyanides, and sulfides in the process. When large amounts of poisoning agents are present, an optional triple junction may be ordered to help prolong the sensor life. Both models, in either the double or triple reference configuration, are made with an outer ceramic junction constructed in an annular design around the pH/ORP-sensitive membrane.

pH Sensor - Fluoride Service (372)
PH measurement has historically been conducted using thin glass membrane electrodes that slowly dissolve in water, creating a pH sensitive surface layer. Some chemicals and/or conditions accelerate this dissolution process, causing the electrodes to become very fragile and prone to breakage. Examples include high temperatures, caustic exposure, steam exposure, and exposure to hydrofluoric acid. Hydrofluoric acid (HF) is commonly used to etch glass and chemically attacks the silicon-oxygen bonds that hold the glass matrix together.
