Hanna® GroLine Waterproof Hydroponic pH Tester (Model HI98118)

The HI98118 GroLine pocket pH Tester is an affordable way to measure the pH of hydroponic nutrient solutions.

The maintaining of an optimal pH is essential to maximize optimum growth.

The general rule of thumb is that as pH increases the solubility of minerals and nutrients decrease.

It is important that nutrients are soluble for plants to uptake and use for growth.

The pH of nutrient solution can also affect the bacteria that fix nitrogen for the plant to use.

Every plant has optimum pH levels for growth.

The Hanna pH meter can also be used to measure the pH in soils as well as nutrient solutions.

To measure the pH of soil as a slurry the USDA recommends a mixture of 1 part soil to 1 part water.

The slurry is allowed to rest for 10 minutes so that the solids will settle out and the pH of liquid above can be measured.

The front of the meter has two buttons.

One is for turning the meter on and off while the other is used to enter the calibration mode.

There is a third button in the battery compartment that allows the user to customize the meter to their preference.

Customization includes temperature readout in oC or oF, automatic shut off selectable from 8 minutes, 60 minutes or disabled, and lastly the choice of using Hanna's Quick Cal pH/EC standard or traditional buffers values of pH 4.01, 7.01 and 10.01.

 

HI98118 GroLine is supplied with protective cap, (3) HI50036 Quick Cal calibration sachets (20 ml), (1) HI700601 general purpose cleaning solution sachet (20 ml), (1) CR2032 battery, instruction manual, and quality certificate.
