The YSI Model 3100 Instrument is a benchtop, microprocessor-based conductivity, salinity, and temperature meter for laboratory use, with automatic temperature compensation, one-point calibration, adjustable temperature coefficient, an LCD screen, and automatic range searching for easy operation. The meter has a 7-pin mini DIN cell connector and takes a wide variety of YSI cells (3200 and 3400 series) including dip, fill, and flow-through types (not included). Some of these cells require an adapter (not included). The meter has UL, CSA, and CE certifications. 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.

H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.
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.
YSI manufactures instruments, sensors, and software for environmental water quality monitoring and testing. The company, founded in 1948 and headquartered in Yellow Springs, Ohio, meets International Organization for Standardization (ISO) 9001 standards.
