Hanna Instruments HI983303-01 Pronto EC Meter, 0 to 1990 µS/cm, 10 µS/cm Resolution, +/-2% Accuracy, 115V

The Hanna Instruments HI 983303-01 Pronto EC Meter is a water-resistant 115V conductivity meter designed for simple, continuous monitoring of conductivity with low maintenance and has automatic temperature compensation, manual one-point calibration, and a red LED alarm that blinks if the measured value differs from the set point more than 100 μS/cm. The meter comes with the HI 7634/2 probe, which is a replaceable 2-pin probe with a 2m cable. The 12V DC power supply allows continuous monitoring over extended periods of time. The housing is sealed against vapors and humidity, with an IP54 rating. 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.
