Key benefits

With an external pH electrode and clear digital readout, it helps you monitor soil conditions that directly impact nutrient availability, plant health and overall crop performance.

• Field-ready durability: IP67 protection for wet, demanding environments.
• Direct soil measurement: insert the electrode and read pH instantly on the digital display.
• High accuracy: supports better decisions on fertilization and soil correction.
• Easy viewing: adjustable display orientation and Data-Hold function for convenient reading.
• Ready to operate: includes batteries and calibration solutions for quick setup.

Recommended applications

Ideal for measuring pH in soils and substrates near the surface, as well as checking horticultural irrigation solutions used in greenhouses and farms. For very compact soils or when the electrode cannot reach sufficient depth, you can prepare a soil solution (soil sample + distilled water) to obtain a representative pH value, including measurements aligned with standard procedures.

Technical highlights

• External electrode with cable for flexible measurements.
• Automatic calibration with pH 4, 7 or 10 buffer solutions (no adjustment screws required).
• Auto power-off after 10 minutes of inactivity to extend battery life.
• Maintenance best practice: rinse the electrode with distilled water after each measurement for longer service life.
