Description
H 63 is a pH combination electrode with plug-head connector, glass shaft and platinum diaphragm designed for accurate laboratory pH determination. It spans the full measuring range of 0 to 14 pH and operates safely from 0 to +100 °C. Filled with KCl 3 mol/l electrolyte and equipped with the Silamid® reference system plus a spherical H-glass membrane, the sensor delivers stable, fast-responding readings in aqueous media. The extended glass shaft measures 320 mm in length and 12 mm in diameter, making it especially suitable for deeper vessels, tall beakers or process-sample containers. Available as a single unit from manufacturer SI Analytics – a Xylem brand, the H 63 combines measuring and reference elements into one durable probe that simplifies installation and handling via the plug head. Its platinum diaphragm maintains a reliable liquid junction potential for reproducible results. Laboratories performing quality control, research or routine monitoring will appreciate the longer immersion length when working with larger sample volumes or specialised apparatus.

Questions about H 63, pH combination electrode with plug head with glass shaft, platinum
What is this article?
H 63, pH combination electrode with plug head with glass shaft, platinum is the article on this page. Luminix Health distributes SI Analytics - a Xylem brand for laboratory use. It sits in Stirring shafts, propellers & impellers, inside Stirring, shaking & mixing, in Lab instruments.
A shaft, a propeller or an impeller is the wetted end of an overhead stirrer. The diameter and the pitch decide whether the liquid turns over. The material, stainless steel or PTFE, decides what the liquid may be. The chuck size has to match the stirrer.
Stirring keeps a mixture uniform or helps a solid dissolve. A magnetic stirrer spins a bar inside a closed vessel. An overhead stirrer drives a shaft when the liquid is viscous or the volume is large. A vortex mixer agitates a tube. A shaker moves a whole rack or a plate. The shape of the impeller and the speed decide whether the liquid turns over or merely spins. The vessels being stirred are indexed under ISO laboratory glassware.
