Item# (PN): CDH-SD11_serie Shipping and Payment

The OMEGA™ CDH-SD11 is innovative and easy to operate. What sets the CDH-SD11 apart from other conductivity meters is that it incorporates a real-time SD card data logger. The CDH-SD11 measures conductivity, TDS (Total Dissolved Solids) or salt concentration using a graphite plate electrode for long life. Downloading data from the SD card into an Excel spreadsheet allows the user to do further data or graphical analysis without special software.

The CDH-SD11 has a wide variety of applications from water conditioning, aquariums, beverage manufacturing and fish hatcheries to food processing, photography, paper and plating industries, educational and other laboratories.

An Introduction to Industrial pH Measurement

What is pH? pH, which is the measurement of hydrogen ion concentration, describes the degree of acidity or alkalinity of a solution. pH measurement as well as pH control is a critical factor in a wide range of industrial applications – including pharmaceutical manufacturing, food and beverage production, dairy and agriculture, water treatment applications, and countless others.

pH control is often vital in ensuring the quality of a product...
