GS2-E Spear pH Electrode for GroStar GS2

The GroStar™ GS2-E Spear pH Electrode is the replacement electrode for the GroStar™ GS2 pH Pen Tester. It is also compatible with the GroStar™ GS1 and GroStar™ GS4. Enables direct pH & temperature measurement in soil, coco, rockwool, and many other media types as well as in nutrient solutions, so no need to prepare soil slurry. The impact-resistant glass membrane is about 10 times stronger than conventional glass electrodes. The PTFE ring prevents the diaphragm from being clogged by soil particles and thus significantly increases durability. Can be attached quickly and easily without additional tools. Compatible with GS1, GS2 and GS4 from the GroStar™ series.
