Digital Electrical Conductivity Meter , Water Conductivity Sensor Self Checking

JFA302 Multifunction Water Analysis Instrument Electrical Conductivity Meter 1. Product description: Measure principle. Electric conductivity sensor is made of glass-platinum electrode. The measure principle of instrument, put two disc(electrical conductivity patch) in the sample solution, and then add a voltage in the disc, the current will be measured. Generally, voltage is sine wave form. Conductivity is determined by Ohm formula, according to voltage and current value. 2.
