Designed to fit comfortably in your hand, with large easy to read LCD display, shows both EC or TDS 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 point calibration.\u003c\/p\u003e\n\u003cp\u003eThe GroLine Waterproof EC\/TDS Tester is made specifically for hydroponics, providing a simple, inexpensive solution to measure fertiliser concentration in a nutrient solution.

Maintaining an optimal pH is essential to maximise optimum growth. The general rule of thumb is that as pH increases the solubility of minerals and nutrients decrease.

Every plant has optimum pH levels for growth. Below is a table for the ideal pH range for a variety of plants.\u003c\/p\u003e\n\u003cp\u003eThe HI-98118 can be used to measure the pH in soils as well as nutrient solutions. To measure the pH of soil as a slurry it is recommended to use 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 the liquid above can be measured.\u003c\/p\u003e\n\u003cp\u003eThe HI-98118 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 customise the meter to their preference. Customisation includes temperature readout in °C or °F, 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.\u003c\/p\u003e\n\u003cp\u003eThe electrode features a unique extractable cloth junction.\u003c\/p\u003e\n\u003cp\u003eThe reference junction of a pH electrode, also known as a salt bridge, provides an electrical pathway between the internal reference cell and the sample. Any clogging of the junction will result in a disruption of the electrical pathway.\u003c\/p\u003e\n\u003cp\u003eWhen this happens the readings will be erratic and take a very long time to stabilise. With the Hanna extractable junction a small portion of 1\/8\" is extracted or pulled to expose a clean surface. With the junction renewed the clogging is cleared allowing the meter to still be used. The overall length of the junction is about 1\" so the junction should only be extracted periodically.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOther Hanna Groline Products\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-groline-cleaning-solution-for-ph-electrodes-120ml\"\u003eCleaning Solution\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-groline-quick-cal-for-phec-120ml\"\u003eQuick Calibration for pH and EC\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-groline-storage-solution-for-ph-electrodes-120ml\"\u003eStorage pH Solution\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-groline-ph-tester-hi-98115\"\u003e98115 pH Meter\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-instruments-groline-waterproof-ph-temperature-tester\"\u003e98118 pH\/Temperature Meter\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-instruments-groline-waterproof-ecppm-tester\"\u003e98318 EC\/TDS\/Temperature Meter\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-groline-phectdstemperature-meter-hi-9814\"\u003e9814 pH\/EC\/TDS Meter\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-groline-monitor-hi-981420\"\u003e981420 pH\/EC\/Temperature Meter\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HANNA","offers":[{"title":"Default Title","offer_id":42366070620375,"sku":"5899","price":89.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0561\/9092\/7032\/products\/nutrient-mangement-hanna-instruments-groline-waterproof-ph-temperature-tester-36571166376151.jpg?v=1780156446"},{"product_id":"hanna-groline-monitor-hi-981420","title":"Hanna Groline pH\/EC\/Temperature Monitor HI-981420","description":"\u003cp\u003eMake your nutrient solution easy to manage with the GroLine Monitor and combined pH\/EC\/Temperature probe.

This is very important to note because, during calibration, the instrument assumes that the electrode is clean and that the standardisation curve created during the calibration process will remain a valid reference until the next calibration.\u003c\/p\u003e\n\u003cp\u003epH 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\u003cstrong\u003eOther Hanna Groline Products\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-groline-cleaning-solution-for-ph-electrodes-120ml\"\u003eCleaning Solution\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-groline-quick-cal-for-phec-120ml\"\u003eQuick Calibration for pH and EC\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-groline-storage-solution-for-ph-electrodes-120ml\"\u003eStorage pH Solution\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-groline-ph-tester-hi-98115\"\u003e98115 pH Meter\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-instruments-groline-waterproof-ph-temperature-tester\"\u003e98118 pH\/Temperature Meter\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-instruments-groline-waterproof-ecppm-tester\"\u003e98318 EC\/TDS\/Temperature Meter\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-groline-phectdstemperature-meter-hi-9814\"\u003e9814 pH\/EC\/TDS Meter\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-groline-monitor-hi-981420\"\u003e981420 pH\/EC\/Temperature Meter\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HANNA","offers":[{"title":"Default Title","offer_id":43823461269719,"sku":"8470","price":11.4,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0561\/9092\/7032\/files\/nutrient-mangement-hanna-groline-cleaning-solution-for-ph-electrodes-120ml-39154677940439.png?v=1684515187"},{"product_id":"hanna-groline-storage-solution-for-ph-electrodes-120ml","title":"Hanna Groline - Storage solution for pH electrodes - 120ml (HI-70300-012)","description":"\u003cp\u003eIt is necessary to store a pH electrode in a solution in order to keep the glass membrane of the pH electrode hydrated.
