Dedicated electrode for measuring the pH of soil and soil mixtures

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

The Specialized Electrode for pH is a rugged, durable pH sensor designed for demanding environments such as plating baths, wastewater treatment, and industrial process control where standard electrodes fail. Industrial sources like the Hanna Instruments chemical‑resistant electrode overview explain that rugged electrodes with reinforced junctions and specialized materials resist fouling and contamination, improving long‑term stability in harsh chemical environments.

Technicians value specialized pH electrodes for their enhanced chemical resistance, fast response and reduced drift, which improve accuracy and reduce maintenance compared with general‑purpose sensors. According to industry guides on pH measurement best practices such as the Omega Engineering pH electrode selection guide, choosing a sensor suited to the specific solution chemistry is essential for reliable quality control and consistent process monitoring in industrial applications.

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

A stability indicator on the screen guarantees the utmost assurance in your results. The selectable auto-shutdown feature prolongs battery life, providing reassurance and conserving energy if the meter is unintentionally 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 soil pH tester HI981030 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.

Tapered glass tip

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.

To expand your pH measurement capabilities beyond a standard probe, consider these specialized pH electrodes designed for different applications such as low-volume testing, surfaces, food, aquaculture, or industrial processes:

• sensION+ 5050T Portable pH Electrode – Rugged combination electrode for portable and field pH measurements in liquids.
• Digital Flat Tip pH/Temperature Electrode – Flat tip design for surfaces, gels, and semi-solid samples where standard bulbs cannot be used.
• Ohaus pH Electrode STSURF – Ideal for surface measurement in foods, gels, or bulk solids.
• Extech Waterproof pH Electrode – Durable and waterproof for on-site, wet environment, or aquaculture measurements.
• Triplett PH050 Mini pH Electrode – Miniature electrode suitable for low-volume samples, bottles, or small containers.
• InLab Ultra-Micro-ISM MicroPin pH Electrode – Micro-pin electrode for very small sample volumes (µL) and microplate applications.
• IntelliCAL PHC281 Ultra Refillable Electrode – High-end refillable probe for analytical and industrial applications requiring longevity and stability.
• Sensorex Self-Cleaning Electrode S650CD – Self-cleaning design to prevent fouling in wastewater, fermentation, or industrial processes.

When choosing a specialized electrode, consider tip geometry (flat, spear, or micro), environment (wet, industrial, or lab), and whether refillable or gel-filled construction is needed for durability and performance.
