The HI98168 is a rugged, waterproof, portable pH meter that allows for the direct measure of soil pH. This meter is supplied with a specialized pH electrode that has a rugged conical tip for insertion in soil
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.
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
As electrolyte is lost over time it can be replenished to extend the life of the electrode.
This secure waterproof connector allows for a single cable to be used for both pH and temperature measurements
We believe that buying a meter should be simple. Your GroLine Portable Soil pH Meter is equipped with everything you need for successful testing right out of the box.
Before using your soil pH meter always make sure that your meter is calibrated with fresh buffer solutions and thats why your soil pH meter is supplied with pH 4.01 and pH 7.01 buffers.
We know the soil science and thats why we provide all the accessories to make your soil testing simple and accurate. Your soil pH meter is supplied with soil sample preparation solution, cleaning solution for soil deposits and ground auger. HI98168 also supplied with calibration vessel and beakers in the rugged carrying case and a USB cable to transfer data to PC.
The meter is supplied with a compact, durable HI720161 carrying case and is thermoformed to hold all necessary components for storage, including the meter and electrode, beakers, auger, soil preparation solution, buffer solutions, and cleaning solutions.
