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.\u003cbr\u003e\u003cbr\u003eThe 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.\u003cbr\u003e\u003cbr\u003eTo 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.\u003cbr\u003e\u003cbr\u003eThe 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.\u003cbr\u003e\u003cbr\u003eThe HI98118 features a cloth junction.

Electrical noise can come from motors and pumps that are common in greenhouses. The single reference junction design of the pH electrode has a cloth junction that allows ion movement between the inner gel electrolyte and the sample being measured. The advantage of the cloth junction is that it can be extracted from the probe, exposing a fresh surface when readings become drifty or erratic. These features make this probe ideal for use in fertilizer solutions.\u003c\/p\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003e \u003ch4\u003eAmperometric EC\/TDS Sensor\u003c\/h4\u003e \u003cp\u003eEC\/TDS readings are performed by a two-pin amperometric sensor.

It is necessary to store a pH electrode in a solution in order to keep the glass membrane of the pH electrode hydrated. Ideally a storage solution should be used; never store an electrode in distilled or deionized water. The Hanna Instruments storage solution is specifically formulated to minimize microbial growth and to prevent any diffusion\/osmotic effects from storing a probe in a solution with the highly concentrated inner reference electrolyte. Storing your pH and\/or ORP electrodes in a storage solution will also keep the junction clear. Maintaining the hydrated layer and clear junction will help to ensure a fast and reliable measurement. In the case of cleaning your pH electrode in one of our cleaning solutions, we recommend soaking the electrode in the HI70300-012 GroLine storage solution for at least one hour before taking measurements.\u003c\/p\u003e \u003cul\u003e \u003cli\u003eSpecial formulation to minimize microbial growth and osmotic\/diffusion effects between the solution and inner reference electrolyte\u003c\/li\u003e \u003cli\u003eManufactured specifically for pH and ORP electrodes\u003c\/li\u003e \u003cli\u003eClearly marked expiration date and lot number\u003c\/li\u003e \u003c\/ul\u003e \u003cdiv\u003e \u003cdiv\u003e \u003cdiv\u003e \u003cdiv\u003e\u003cform\u003e \u003cdiv\u003eHI70300-012 is a GroLine storage solution that can be used to store your pH electrode*.

Placing the electrode in a small glass filled with storage solution or replacing the solution in the protective cap is a suitable way to store the electrode.
