pH sensors from EMEC: Accuracy and Long-term Stability

At Dosing Pump Shop, we offer a wide range of high-quality pH sensors from EMEC, known for their reliability and precision in dosing systems. EMEC pH electrodes provide long-term stability and accuracy, which is essential for the most critical measurements in various applications such as water treatment, pool maintenance and industrial processes.

Features of EMEC pH sensors:

• Accurate Measurements and Fast Response: EMEC pH sensors deliver accurate readings and fast response, which is crucial for efficient process control.
• Robust Construction: The electrode housing is made of Epoxy, which ensures long life and constant use. The electrolyte in the electrode is KCl in gel form and is maintenance-free.
• Various Models: Both single-junction and double-junction models are available. Dual-junction models are particularly suitable for seawater and offer better electrode protection, ensuring a longer service life. They are recommended when working with materials such as sulphide, sulphur and silver.
• Wide Measuring Range: EMEC pH sensors have an operating range of $0-14\text{ pH}$ and a resolution of $0,01$.
• Connection options: The electrodes come with a coaxial cable and BNC connector, and are also available with an SN6 connector on request.

Lifetime and Maintenance: The lifetime of an electrode is affected by working conditions, such as temperature and the type of solution (acidic or alkaline). At room temperature and a weak solution, the lifespan is usually around 2 years. A higher temperature drastically shortens the lifespan.

Regular maintenance and calibration is required for optimal performance. This includes cleaning the electrode with clean water and a mild acid solution (up to 10% HCl) if the measurement becomes sluggish or unstable. During calibration, the electrode should be shaken to dry, not wiped, to avoid electrostatic charges. Always use fresh buffer solutions for calibration.

Storage: Always keep electrodes in their original storage bottles with the transparent KCl liquid at $pH4$. Never let the electrodes become dry; store them in water for short periods of time. The recommended storage temperature is $10$ to 30∘C ($50$ to 86∘F).
