Hanna GroLine Hydroponic Tester HI98131 | pH, EC, TDS, Temp Living Soil Produced with Swiss technologyWhy the GroLine Hydroponic Tester Outlasts a Sealed Pen The electrode comes out. On most pocket pH meters the probe is sealed in, so when it dies the meter goes in the bin with it. Here the HI73127 electrode unscrews using the HI73128 tool that comes in the box.
