pH Meters and Conductivity Meters

pH meters and conductivity meters are measuring instruments used in investigating the properties of liquids. Both can easily measure by simply immersing an electrode in a liquid. They are widely used in a variety of fields including process control and quality control at factories and the like and at medical institutions, public institutions, and the like. pH meters investigate the alkalinity or acidity of liquids by measuring hydrogen ion density in liquids. Conductivity meters are used to measure the electrical conductivity of liquids to find how well they conduct electricity. There are those with waterproof specifications suitable for use outdoors and around water. They can be benchtop types and stationary types as well as handheld types and pen types that are convenient for carrying around. The measurable range differs by product, so products that fit the application are used. Also, caution is necessary as continuous use in strong acid or alkaline and measuring hot liquids may affect electrode lifespan.
