Our ES-2 sensor is threaded so it can be inserted into a 1/2″ NPT junction to measure the electrical conductivity of runoff, or irrigation water. An optional screened cap allows the ES-2 to be submerged into a tank or waterway without sediment build on the contact points. Electrical conductivity, which responds to salinity can be crucial in identifying trends in fertilizer runoff.
