GroLine Direct Soil and Soilless pH Electrode

The GroLine Direct Soil and Soilless pH Electrode HI12943 by HANNA Instruments is used for the direct measurement of pH in soil and soilless media. The glass body, refillable, single junction pH electrode with a DIN connector that is compatible with the HI9814 Groline portable pH/EC/TDS meter. This electrode has a triple ceramic junction in the outer reference cell and the conic pH sensing tip is made with low temperature glass. There is an integrated amplifier and built-in temperature sensor for automatically temperature compensated pH readings. The design consideration for the HI12943 is ideal for pH measurements in rockwool, coconut cour, perlite and other soilless substrates. It can only be used with Hanna's Waterproof Portable Hydroponics pH/EC/TDS/Temperature Meter Kit HI9814.  Triple Ceramic Junction Low Temperature Glass Built-in Temperature Sensor The pH Electrode uses low temperature (LT) glass, conic bulb, glass body, triple ceramic junction, and is refillable with 3.5M
