Pen Tester Kit 5-in-1 for pH/EC/ppm/Temperature, GroStar® GS4 Gen II

Description

GroStar® GS4 5-in-1 pH/EC/ppm/Temp Combo Pen Tester Gen II for Growers, also known as a grower-focused 5-in-1 combo pen tester, is designed for users who need practical measurement of pH, nutrient strength and temperature from one compact tester.

This tester is suitable for growers, horticulture users, hydroponic setups, greenhouse teams, education facilities and crop-management applications where regular monitoring of growing solutions helps support better control of crop conditions. The combo pen format is useful for routine checks where users want to reduce the need for separate pH and conductivity testers. It supports day-to-day testing in nutrient tanks, growing systems, preparation areas and other grower testing workflows.

The backlit display and calibration workflow help make operation easier during regular use, while TruRead mode supports a more complete view of readings taken across different sample points. The replaceable probe format supports longer-term use of the tester body when the probe reaches its end of life. Users should confirm the correct replacement probe, calibration solutions and storage procedure before ongoing use.

LabChoice Australia supplies GroStar® GS4 Combo Pen Testers for growers, schools, universities, horticulture users, hydroponic applications and testing facilities requiring a practical 5-in-1 tester for pH, EC, ppm and temperature measurement workflows.
