Measure pH in soil and soilless media!
Hanna Instruments designed this electrode for use with their HI9814 GroLine tester via a DIN connector. Find the HI9814 tester
HERE.
This pH electrode allows for the direct measurement of pH in soil and soilless media. Hanna makes the HI1294D with a glass-body, refillable, single-junction pH electrode. This electrode features a triple-ceramic junction in the outer reference cell. They make the conic pH sensing tip with low-temperature glass.
The HI1294D also features an integrated amplifier and a built-in temperature sensor. These features compensate for temperature when taking pH readings.
For use with HI9814 Meter only!
