Professional GroLine Portable Soil pH Meter Hanna Instruments HI98168

Soil pH and HI98168 GroLine pH Meter 

The measurement of pH in agricultural activities 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

Besides being supplied with a unique pH electrode made for soil analysis, the HI98168 has the Hanna’s unique CAL Check™ feature that alerts the user to potential problems during the calibration process. This is a very important since it is likely that the probe will be coated with soil. This coating can easily lead to errors in pH measurement.  By comparing previous calibration data to the current calibration, the meter will inform the user, with display prompts, when the probe needs to be cleaned, replaced, or if the pH buffer might be contaminated.  After calibration, the overall probe condition is displayed on screen as a percentage. The probe condition is affected by both the offset and slope characteristics of the pH electrode, both of which can be found in the GLP data including with the readings stored in the meter or transferred to a PC.

ELECTRODE FEATURES/BENEFITS:

The HI12923 pH electrode that is supplied with the meter 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 HI12923 connects to the HI98168 with a quick-connect, waterproof DIN connector, allowing for a secure, non-threaded attachment

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.

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

Refillable

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

Quick Connect DIN Connector

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