Pen Tester Kit for Soil pH Testing, GroStar® GS2 Gen II, Replaceable Spear Probe

Description

GroStar® GS2 Soil pH Pen Tester Gen II with Replaceable Spear Probe, also known as a grower-focused soil pH tester, is designed for users who need practical pH measurement directly in growing media and nutrient solution workflows.

This tester is suitable for growers, horticulture users, hydroponic setups, greenhouse teams, education facilities and crop-management applications where pH control supports better growing-condition management. The spear-style probe helps users test compatible growing media more directly, reducing the need for a full benchtop meter setup during routine checks. This makes the tester practical for crop rooms, propagation areas, greenhouse benches and other grower testing environments.

The PTFE ring design helps reduce junction blockage during media contact, which is important when testing samples that may contain soil particles or fibrous material. The replaceable probe format also supports longer-term use of the tester body when probe replacement becomes necessary. TruRead mode is useful where readings need to be taken across multiple locations or sample points. It helps users review a more complete result set by showing average, minimum and maximum values from repeated measurements.

Users should confirm the correct testing method for soil, coco coir, rockwool or nutrient solution before use. Proper probe cleaning, calibration and storage are important for stable readings and longer probe service life.

LabChoice Australia supplies GroStar® GS2 Soil pH Pen Testers for growers, schools, universities, horticulture users, hydroponic applications and testing facilities requiring a practical pH tester for direct growing-media and crop-management workflows.
