The 7-in-1 EC600 Kit monitors conductivity, TDS, salinity, resistivity, pH, mV, and temperature. It offers automatic one-button calibration of 4, 7, and 10 pH, with the option of three-point calibration for greater precision, as well as automatic temperature adaptation. One point conductivity calibration automatically detects eight calibration solutions from the United States, Europe, and China. Memory can record up to 300 readings, each with a series number, measured value, and temperature. The meter sports a big, blue backlit LCD display panel and an auto power down mode that can be disabled to save battery life. The IP57 waterproof housing keeps it safe from the elements. The kit includes a pH/mV/temperature electrode, a polymer conductivity cell, pH and conductivity calibration solutions, batteries, and a durable carrying box.

The EC510 is a conductivity test kit. The kit includes the EC500 meter, three calibration standards, three pH buffer pouches with rinse solution, three cups, batteries, and a carrying bag. Uses a single electrode to measure five parameters: conductivity, TDS, salinity, pH, and temperature. Analog bar graphs show trends. Memory can store up to 25 labeled readings. The conductivity-to-TDS ratio can be adjusted from 0.4 to 1.0, whereas the salinity ratio is fixed at 0.5.
