The lightweight and portable pen can test pH, conductivity, or TDS (total dissolved solids) in a single pocket-sized device. The HI98129 can also read the temperature and all the readings are ATC (automatic temperature compensated) which means values will be more accurate.\u003c\/p\u003e\n\u003cp\u003eThe pH electrode can be changed, meaning that you will not have to throw away the HI98129 after the probe has exhausted. Almost all pH sensing devices will last about a year or so until the electrode needs to be replaced, and traditionally you would need to buy a whole new metering pen, now you do not have to replace the meter! Just replace the pH cartridge that houses the electrode, and the sturdy snap-in connector will hold the electrode in place until the next time you need to replace it. \u003c\/p\u003e\n\u003cp\u003eReplacement pH Electrode - \u003ca href=\"https:\/\/www.bulkreefsupply.com\/hi73127-spare-ph-electrode-hanna.html\"\u003eHI73127\u003c\/a\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTDS Range - 0-2000ppm\u003c\/p\u003e\n\u003cp\u003eTDS Resolution - 1ppm\u003c\/p\u003e\n\u003cp\u003eTDS Accuracy - \u003cspan\u003e±2% F.S.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eEC Range - 0-3999\u003cspan\u003eµS\/cm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eEC Resolution - 1µS\/cm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eEC Accuracy - ±2% F.S.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003epH Range - 0.0-14.0\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003epH Resolution - 0.01pH\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003epH Accuracy - ±0.05 pH\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eTemperature Range - 32.0°F to 140°F\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eTemperature Resolution - 0.1°F\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eTemperature Accuracy - ±1°F\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eTemperate Readings - °C or °F\u003c\/p\u003e\n\u003cp\u003eAuto Off - 8 Minutes\u003c\/p\u003e\n\u003cp\u003eDimensions - 6.4\" L x 1.6\" W x 1.0\" H\u003c\/p\u003e\n\u003cp\u003eWarranty - 1 year\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCalibration Settings:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEC\/TDS Calibration - Single Point (\u003cspan\u003e1413 µS\/cm, 1382 ppm)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003epH Calibration - Two Point (4.01\/7.01\/10.01)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eTDS Conversion Factor - 0.45 to 1.00\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eTemperature Compensation - \u003cspan\u003epH (automatic) EC\/TDS (automatic with β adjustable from 0.0 to 2.4% \/ °C)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Included?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e1x HI98129 pH\/EC\/TDS Metering Pen\u003c\/p\u003e\n\u003cp\u003e1x HI73127 pH Electrode (pre-installed)\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Summit City Coral","offers":[{"title":"Default Title","offer_id":52472992006427,"sku":"211107","price":224.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0246\/5100\/5999\/files\/211107-hannainstruments-ph-ec-tds-tester-ph-electrode-testing-fr.webp?v=1783365814","url":"https:\/\/www.summitcitycoral.com\/products\/hanna-hi98129-low-range-ph-conductivity-tds-combo-pen","provider":"Summit City Coral","version":"1.0","type":"link"}
