The wetted side handles standard hydroponic feeds without crazing. The \u003cstrong\u003e1.0 cell constant covers 10 to 10,000 µS\u003c\/strong\u003e — the band where fertigation EC actually sits. The 3\/4 in NPT thread drops into any inline tee or submersion saddle. A 15-foot factory cable connects the electrode to the 2850 electronics. Up to 1,000 feet of cable runs between the electronics and the receiving controller.\u003c\/p\u003e\n\u003ch2\u003eGF Signet 2850 Conductivity Sensor Electronics with EasyCal\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe 2850 is a two-wire transmitter that reports EC on a \u003cstrong\u003e4-20 mA loop\u003c\/strong\u003e.
