Ensure that your data can be trusted with GLP data. Accessible by a fixed dedicated key, this data includes date, time, pH calibration buffers, offset, and slope.
Versatile Data Logging
The HI98168's log-on-demand feature allows you to store up to 100 readings. The AutoEnd button can be used during measurement to hold the first stable reading on the display automatically.
Superior Field Usability
Designed to withstand the knocks, drops, and spills of real life, the IP67 body ensures top performance in any environment. Your meter is better protected against dust and water intrusion from any direction. The Quick Connect DIN provides a water-tight seal without twisting.
Your measurements require detailed attention; so should your electrode. The HI98168 Meter features a built-in probe that has been carefully designed to measure the pH of soil.
Triple Ceramic Junction
The HI12923 has three ceramic frits that allow electrolyte to flow at a high rate from the inside of the probe to the outside. A higher flow rate increases the accuracy of measurements of soil with low moisture.
Conical Glass Tip
The conical shaped tip design allows for penetration into soil and soil slurries.
A glass body is easy to clean, is chemically resistant, and quick to reach thermal equilibrium for a faster, more stable measurement.
We believe that buying a meter should be simple. Your Professional Portable Soil pH Meter is equipped with everything you need for successful testing right out of the box.
Cleaning Solution for Soil and Humus Deposits
Your Soil pH Meter comes with cleaning solution that has been engineered to keep your electrode free from organic materials found in soil. This concentrated combination of detergents cleans your tester quickly and effectively so that your tester stays in optimum condition.
pH 4 & 7 Buffer Sachets
When performing a pH calibration it is important that the correct buffers are used. We include some start buffers to get you going.
Your meter, probe, and accessories are all neatly packaged in a rugged carrying case to ensure that you have everything you need for on-the-go field testing.
