Hanna Instruments, GroLine, Direct Soil and Soilless Media pH Electrode

The Hanna Instruments GroLine Direct Soil and Soilless Media pH Electrode is a 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 automatic temperature compensated pH readings.

The design consideration for the HI12943 is ideal for pH measurements in soils and hydroponics growing media including rockwool, coconut cour, perlite, and other soilless substrates. The HI12943 can only be used with Hanna's HI9814 Groline portable pH/EC/TDS meter. *HI1293 is replacing HI1294D. Both electrodes are compatible with existing models of HI9814.

Hanna Instruments offers a wide variety of pH electrodes that are designed for many different applications. The type of glass used for sensing pH, bulb shape, body material, type of junction, type of reference, and electrolyte used are just some of the design considerations. The HI12943 uses low temperature (LT) glass, conic bulb, glass body, triple ceramic junction, and is refillable with 3.5M KCl + AgCl.
