Oxidation changes both the distance and surface, which will directly affect accuracy. The non-oxidising graphite pins are able to provide an optimal surface for accurate, dependable results.\u003c\/p\u003e \u003cp\u003eWhen calibration is needed, simply submerge the electrode tip into calibration solution and the meter will auto calibrate.\u003c\/p\u003e \u003ch3\u003eFeatures\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eWaterproof\u003c\/li\u003e \u003cli\u003eAutomatic temperature compensation (ATC)\u003c\/li\u003e \u003cli\u003eAutomatic one-point calibration\u003c\/li\u003e \u003cli\u003eMeasurement Stability Indicator\u003c\/li\u003e \u003cli\u003eTemperature measurement\u003c\/li\u003e \u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003e0.00 to 10.00 g\/L (ppt)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e0.01 g\/L (ppt)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e±2% F.S.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTDS Factor\u003c\/td\u003e\n\u003ctd\u003e0.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCalibration Solution\u003c\/td\u003e\n\u003ctd\u003eHI-70038 6.44ppt\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCalibration\u003c\/td\u003e\n\u003ctd\u003eAutomatic, 1 point\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Compensation\u003c\/td\u003e\n\u003ctd\u003eautomatic, 0 to 50°C (32 to 122°F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Type \/ Life\u003c\/td\u003e\n\u003ctd\u003eCR2032 3V Li-ion approx. 250 hours of continuous use\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnvironment\u003c\/td\u003e\n\u003ctd\u003e0 to 50°C (32 to 122°F); RH max 100%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e160 x 40 x 17 mm (6.3 x 1.6 x 0.7\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e75g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrdering information:\u003c\/td\u003e\n\u003ctd\u003eHI-983024 is supplied with protective storage sleeve, CR2032 battery and instructions, quality certificate and 6.44 ppt calibration solution sachets x 4.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eDownloads\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/www.hannainstruments.co.uk\/modules\/teapotknowledgehub\/uploads\/ist983024_11_20-6271181622b16.pdf\" target=\"_blank\"\u003eHI-983024 TDS Tester (PDF)\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640110719349,"sku":"HI-983024","price":75.81,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/hi-983024-pool-line-tds-tester-with-amperometric-graphite-electrode_d9567316-3def-410f-8a73-39bbc361363d.jpg?v=1791581612","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-983024-pool-line-tds-tester-with-amperometric-graphite-electrode","provider":"Test All Water","version":"1.0","type":"link"}
