Get Down to Basics
Plants need plenty of sun, air, water, and nutrients to grow. But how can you make sure your plants have enough nutrients? Measuring different aspects of soil can tell you exactly what you need and what your missing, and help you to foster strong and healthy plants.
Direct Soil Conductivity Tester
Specifically designed to directly measure soil conductivity (EC) and temperature with steel penetration electrode.
pH Meter for Direct Soil Measurement
Specialized probe that can be directly inserted in moist or soft soil. For harder soils, the kit includes a plastic auger to perforate the ground.
GroLine Waterproof Combo Meter
One combined, pre-amplified pH, EC, and TDS (ppm) probe for hassle-free measurements.
Simple. Original. Smart.
HALO® Wireless Soil pH Meter
Upgrade to a wireless pH testing experience for better quality.
Our HALO® Wireless Soil pH Meter features a triple ceramic junction in the outer reference cell, built-in temperature sensor, and the conic pH sensing tip making it ideal for pH measurements in soil samples. Take direct pH and temperature measurements using your smartphone or tablet.
Accurately Measure EC/TDS
The HI98330 nutrient tester is designed to measure the conductivity of the nutrient solutions used in agriculture and hydroponic applications.
