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.

Hanna suggests cleaning the bulb and junction of your electrode on a regular basis to ensure that the probe is always clean and to prevent any clogging of the junction. The HI7061-050 is for 500 mL of general purpose cleaning solution.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSpecially formulated for cleaning electrodes\u003c\/li\u003e\n\u003cli\u003eAir tight seal to ensure quality\u003c\/li\u003e\n\u003cli\u003eExpiration date and lot number\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"hs_cos_wrapper_widget_12054562854\" class=\"hs_cos_wrapper hs_cos_wrapper_widget hs_cos_wrapper_type_module\" data-hs-cos-general-type=\"widget\" data-hs-cos-type=\"module\"\u003e\n\u003csection class=\"banner--product-rich-text\"\u003e\n\u003cdiv class=\"grid-container\"\u003e\n\u003cdiv class=\"align-center\"\u003e\n\u003cdiv class=\"cell small-12 large-10\"\u003e\n\u003cdiv id=\"hs_cos_wrapper_widget_12054562854_\" class=\"hs_cos_wrapper hs_cos_wrapper_widget hs_cos_wrapper_type_inline_rich_text\" data-hs-cos-general-type=\"widget\" data-hs-cos-type=\"inline_rich_text\" data-hs-cos-field=\"content\"\u003e\n\u003cp\u003eThe most common cause for pH measurement inaccuracies is an unclean or improperly cleaned electrode.

Ideally a storage solution should be used; never store an electrode in distilled or deionized water. The GroLine 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.

This is very important to note, because during calibration, the instrument assumes that the electrode is clean and that the standardization curve created during the calibration process will remain a valid reference until the next calibration. pH meters on the market today will allow an offset voltage of approximately ±60 mV. The deviation from 0 mV is not unusual but ideally should be no greater than ±30 mV. The calibration process compensates for the change in offset voltage. If the mV offset continues to deviate and the meter is calibrated with a dirty electrode then inaccurate readings will result.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/www.hannainst.com\/hs-fs\/hubfs\/001-website\/images\/electrode-cleaning-illustration.gif?width=528\u0026amp;name=electrode-cleaning-illustration.gif\" alt=\"electrode-cleaning-illustration\" width=\"528\" srcset=\"https:\/\/www.hannainst.com\/hs-fs\/hubfs\/001-website\/images\/electrode-cleaning-illustration.gif?width=264\u0026amp;name=electrode-cleaning-illustration.gif 264w, https:\/\/www.hannainst.com\/hs-fs\/hubfs\/001-website\/images\/electrode-cleaning-illustration.gif?width=528\u0026amp;name=electrode-cleaning-illustration.gif 528w, https:\/\/www.hannainst.com\/hs-fs\/hubfs\/001-website\/images\/electrode-cleaning-illustration.gif?width=792\u0026amp;name=electrode-cleaning-illustration.gif 792w, https:\/\/www.hannainst.com\/hs-fs\/hubfs\/001-website\/images\/electrode-cleaning-illustration.gif?width=1056\u0026amp;name=electrode-cleaning-illustration.gif 1056w, https:\/\/www.hannainst.com\/hs-fs\/hubfs\/001-website\/images\/electrode-cleaning-illustration.gif?width=1320\u0026amp;name=electrode-cleaning-illustration.gif 1320w, https:\/\/www.hannainst.com\/hs-fs\/hubfs\/001-website\/images\/electrode-cleaning-illustration.gif?width=1584\u0026amp;name=electrode-cleaning-illustration.gif 1584w\" sizes=\"(max-width: 528px) 100vw, 528px\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan id=\"docs-internal-guid-f72f4f28-11fe-b133-ab0a-db21cdd384ef\"\u003eCleaning is a fast and effective routine that should be performed on a regular basis as a preventative measure against using a dirty electrode and to ensure that the junction is not clogged.

It provides the buffering capacity that stabilizes pH and supplies carbonate ions essential for coral skeleton formation and calcification. Optimal alkalinity levels (typically 7-11 dKH or 125-200 ppm) ensure healthy coral growth, vibrant colors, and stable water chemistry. Low alkalinity causes pH swings and stunted coral growth, while high alkalinity can lead to precipitation and tissue damage. The HI755's 0-300 ppm range covers the full spectrum of reef tank alkalinity levels for precise monitoring.\u003c\/p\u003e\u003ch3\u003eHow to Use:\u003c\/h3\u003e\u003col\u003e\n\u003cli\u003eFill cuvette with 10 mL saltwater sample to line\u003c\/li\u003e\n\u003cli\u003eAdd HI755 reagent packet and mix thoroughly\u003c\/li\u003e\n\u003cli\u003eWait for color development (1 minute)\u003c\/li\u003e\n\u003cli\u003eInsert cuvette into HI755 Checker HC\u003c\/li\u003e\n\u003cli\u003ePress button to read alkalinity in ppm (mg\/L) CaCO₃\u003c\/li\u003e\n\u003cli\u003eConvert to dKH if desired: dKH = ppm ÷ 17.9\u003c\/li\u003e\n\u003c\/ol\u003e\u003ch3\u003eReagent Availability:\u003c\/h3\u003e\u003cp\u003eReplacement reagents available separately as HI755-26 (25 tests).
