Reed Instruments YK-30WA Water Quality Tester

The Reed YK-30WA is a portable conductivity tester with automatic temperature compensation and an LCD screen. This meter measures electrical conductivity from 0 to 1,999 microsiemens/cm for a wide range of water quality applications. It has automatic temperature compensation (ATC) for accurate readings in fluctuating temperatures. The LCD screen displays readings and indicators. Its cabled probe is useful for demonstrating before and after results of conditioning and filtration systems. The data hold function stores readings for later review. Conductivity meters are commonly used in the water-quality testing, waste-water treatment, hydroponics, agriculture, and aquaculture industries, in cosmetics manufacturing, and in laboratory research.

Conductivity meters, also known as electrical conductivity (EC) meters, measure the ability of a solution or material to conduct an electrical current. This measurement helps determine if the solution is, for example, contaminated or contains too much saline. In general, pure solutions, such as distilled water, have low conductivity. More saline- or nutrient-rich solutions, such as seawater or fertilizers, have high conductivity. Conductivity measurements are often used with total dissolved solids (TDS) measurements, which are typically expressed in ppm (parts per million). TDS consist of dissolved minerals and salts. To determine the amount of TDS, conductivity is measured, and the result is converted to a TDS measurement. Different meters provide results for conductivity, TDS, or both, and the application determines meter selection. Conductivity meters are used in research laboratories and a variety of industries, such as water-quality testing, waste-water treatment, hydroponics, agriculture, aquaculture, and cosmetics manufacturing.

Reed Instruments manufactures test and measurement equipment such as pressure gauges, electrical testers, temperature and humidity instrumentation, and inspection instruments. The company, founded in 2004, is headquartered in Wilmington, NC.
