The Soil pH Tester HI981030  is designed for taking direct pH measurements in soil for environmental and agricultural testing.

The built-in probe features an open reference junction, conical glass tip, and a removable sleeve design making it ideal for measuring the pH of soil.

Better Features for Better Testing

An on-screen stability indicator ensures the highest level of confidence in your results. Selectable auto-shutdown function extends battery life for peace of mind and energy savings if the meter is accidentally left on.

Pocket size

Thanks to its compact size, the soil pH tester is ideal for testing on the move. A large LCD display provides at-a-glance readings from any angle. One-button operation simplifies the testing process.


Long battery life

The CR2032 Li-ion battery supplied offers up to 1000 hours of continuous use. The battery icon will flash to let you know when it's time to change the battery, so you never miss a measurement.

Your measurements need special care; so does your electrode. The HI981030 soil pH tester features a built-in probe that has been carefully designed to measure soil pH directly for environmental and agricultural testing.

Single open joint with removable sleeve

When readings become slow, simply remove the sleeve for quick cleaning and fresh electrolyte. Having a clean probe with fresh reference electrolyte will improve performance and extend tester life.

Pointe de verre conique

The tapered tip design allows penetration into soil and soil sludge.

PVDF body

Polyvinylidene fluoride (PVDF) is a durable plastic resistant to most chemicals and solvents used for disinfection, including chlorine (bleach).

We think buying a tester should be simple. Your soil pH tester is equipped with everything you need for successful testing.

Cleaning solution for soil and humus deposits

Your soil pH tester comes with a cleaning solution designed to protect your electrode from organic matter in the soil. This concentrated combination of detergents cleans your tester quickly and effectively to keep it in optimum condition.


Buffer Sachets pH 4 & 7 

When calibrating pH, it's important to use the right buffers. We include starter buffers to get you started. The single-use sachets are individually sealed, so you can use a new buffer each time you calibrate.

Storage solution

Correct storage of your electrode will ensure reliable measurements and long electrode life. Our storage solution is specially formulated to keep glass pH hydrated while minimizing organic growth.
