Featuring automatic temperature compensation, a battery life indicator, and an advanced cloth junction sensor, it delivers fast, reliable pH measurements essential for optimizing plant nutrient uptake. Its user-friendly interface supports customizable auto shut-off and quick calibration, making it the go-to tool for millennial growers seeking precision and convenience in one sleek device.

## Description

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. Below is a table for the ideal pH range for a variety of plants. The HI98118 can be used to measure the pH in soils as well as nutrient solutions. The North Carolina State University has outlined a procedure known as Pour Through Sampling Method. This method is used for container plants in which 50 ml of leachate is collected from a thoroughly watered plant and then tested. 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 HI98118 is an advanced meter while maintaining simplicity. 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. The HI98118 features a cloth junction. The reference junction of a pH electrode, also known as a salt bridge, provides an electrical pathway between the internal reference cell and the sample. A cloth or fiber wick juction provides a larger surface area than a standard ceramic junction.

Review: Best ph pen - Best ph pen on the market definitely would get another one. This one is more accurate and reads the ph of the water faster than blue lab or VIVOSUN . Also calibrating this ph pen is so easy because there literally only 1 point calibrations but you could also do 2 or 3 point if you’d like.
Review: Not accurate. Calibrates fine, but gives incorrect read outs. - Usually hanna products are great. This one for some reason IS NOT. I have 2 of these meters as well as 3 of the hanna continuous monitors......after a fresh calibration on everything that calibrated with no errors...this particular unit will not read the same values as the others. Cant be trusted, therefore it goes in the trash. Wish I would have returned it when I had the chance.
