Hanna Instruments HI981030 GroLine Soil pH Tester

Direct Soil pH Testing • ±0.05 pH Accuracy • Renewable Junction • Complete Kit Included

The Hanna Instruments HI981030 GroLine Soil pH Tester is a compact, professional-grade tool designed for direct soil pH measurement in agriculture, environmental monitoring, landscaping, and greenhouse management. Built for real-world soil testing, it delivers ±0.05 pH accuracy with 0.01 pH resolution, allowing you to spot-check soil conditions quickly and make better decisions about amendments, irrigation, and nutrient availability.

Unlike basic testers, the HI981030 uses a specialized soil electrode with an open junction reference and replaceable bridge electrolyte—a design that improves performance in challenging samples like soil and soil slurries, while extending electrode life through easy cleaning and refresh.

Why Choose the GroLine HI981030 for Soil pH?

✔ Direct Soil pH Measurement (Spot Checks + Slurries)

This tester is engineered specifically for measuring pH in soil and soil slurries, making it ideal for field scouting, greenhouse pots, raised beds, and environmental sampling.

✔ Accurate Results You Can Trust

  • pH Accuracy: ±0.05 pH @ 25°C
  • Resolution: 0.01 pH
  • Range: 0.00 to 12.00 pH

An on-screen stability indicator confirms when readings have stabilized so you can record results confidently.

✔ Renewable Junction for Faster Readings & Longer Life

The rugged PVDF body (abrasion- and chemical-resistant) includes a removable outer junction sleeve. You can remove and clean the sleeve, then refresh the junction by adding a small amount of gel electrolyte—helping restore response speed and extend the tester’s life.

✔ Open Junction Reference (Built for Soil)

The open junction uses a solid gel interface between the sample and the internal Ag/AgCl reference—better suited for dirty, organic, and particulate-rich samples than typical sealed junction designs.

✔ Pocket-Sized, One-Button Operation

Simple single-button use with a large LCD makes it easy for anyone to test quickly in the field.

✔ Long Battery Life + Smart Auto-Off

A CR2032 battery provides up to 1000 hours of continuous use. Auto-off can be set to Off, 8 minutes, or 60 minutes, and a blinking battery icon warns when power is low.
