HI-12923 pH & Temperature probe for soil information

Hanna's extended description

It is uniquely designed with a conical tip and a triple ceramic junction for improved performance in soils that have a low moisture content. The probe has a built in amplifier to reduce noise from humidity that can effect the probe connection to the meter. The HI-12923 connects to the HI-98168 with a quick-connect, waterproof DIN connector, allowing for a secure, non-threaded attachment.


As electrolyte is lost over time it can be replenished to extend the life of the electrode.

Triple ceramic junction

The outer reference 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 allows for a pH measurement of soil with low moisture.

Conical tip

The conical tip is made of durable LT glass and allows for direct measurement in soils.

In the case any rocks are present an auger is provided to make a hole for the probe.

Quick connect DIN connector

This secure waterproof connector allows for a single cable to be used for both pH and temperature measurements.

Operates with the HI-98168 Groline pH/temperature meter for soil

The measurement of pH in agriculture is very important due to the influence it has on the growth of the plant. Soil can be acid, neutral or alkaline, according to its pH value. Most plants prefer a pH range from 5.5 to 7.5; but some species prefer more acid or alkaline soils. Nevertheless, every plant requires a particular range of pH, for optimum growth.
