This modern looking meter is only 0.7\" thick and extremely ergonomic, fitting comfortably in your hand. The HI98118 has a very large easy to read LCD display that shows both pH and temperature along with calibration, stability and low battery indicators. All operations are simplified to two buttons. One is for turning the meter on\/off and the other for automatic one or two point calibration.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTwo-Button Operation\u003c\/li\u003e\n\u003cli\u003eQuick Calibration Mode using Hanna Quick Cal pH\/EC Calibration Solution\u003c\/li\u003e\n\u003cli\u003eCloth junction providing a larger surface area than a standard ceramic junction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 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.\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. 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.

The EC range of the HI98131 is from 0.01 to 6.00 mS\/cm and TDS is from 0 to 3000 ppm using a 0.5 conversion factor. The HI98131 also offers the option to use a 0.7 (700 ppm) EC to TDS conversion factor. An exposed temperature sensor allows for rapid temperature compensated measurements of EC and TDS. The LCD screen has indicators for calibration status and stability. The battery percent level is displayed at start up alerting the user to the remaining battery power that is available.

A separate temperature probe is supplied to provide temperature compensated pH measurement. The HI8424 is very basic in operation with automatic calibration to one or two points to any of the three programmed buffer values (pH 4.01, 7.01, and 10.01). The simplicity in operation and the economical price point has made the HI8424 one of the most popular meters available in the market.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003eFeatures at-a-glance\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eWaterproof\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e- Compact, heavy duty casing that is protected against any ingress of water that would damage the electronics.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAutomatic Calibration\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e- calibration to one or two points to any of the three programmed buffer values (pH 4.01, 7.01, and 10.01).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAutomatic Temperature Compensation\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e- Separate temperature probe is supplied to provide temperature compensated measurements.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh Resolution\/Accuracy mV Range\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e- The HI8424 automatically switches resolution from 1 mV to 0.1 mV when ORP readings are between -699.9 to +699.9 mV.

Oxidation changes both the distance and surface, which will affect accuracy. The non-oxidizing graphite pins are able to provide an optimal surface for accurate, dependable results.

Ions are formed when a salt such as sodium chloride is dissolved in water to form particles having electrical charges. Sodium chloride, separates into Na+ and Cl-.

Both are commonly used in the construction of ORP probes.\u003c\/p\u003e\n\u003cp\u003eThe platinum sensor is often preferred because it is mechanically simpler to produce.
