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.

This electrode has a 12-month manufacturer’s warranty.
