These high quality reagents are clearly marked with the lot number and expiry date on each packet for traceability.\u003c\/p\u003e\u003cp\u003eThe HI-93701-03 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. These reagents follow the DPD Method in which the reaction between chlorine and reagent causes a pink tint in the sample. By simply adding the packet of HI-93701-03 reagent to the sample, the reaction will take place and one of Hanna’s compatible benchtop or portable meter will determine the concentration from the colour that is produced. The results will be displayed in mg\/L (ppm) of free chlorine. These reagents are designed to be used with samples that have an expected range of 0.00 to 5.00 mg\/L free chlorine.\u003c\/p\u003e \u003ch3\u003eTip for an accurate measurement\u003c\/h3\u003e \u003cp\u003eIt is important that the sample does not contain any debris.\u003c\/p\u003e \u003cp\u003eWhen the cuvette is placed into the measurement cell, it must be dry outside and completely free of fingerprints, oil or dirt. Wipe it thoroughly with HI-731318 or a lint-free cloth prior to insertion.\u003c\/p\u003e \u003cp\u003eShaking the cuvette can generate bubbles, causing higher readings. To obtain accurate measurements, remove such bubbles by swirling or by gently tapping the cuvette.\u003c\/p\u003e \u003cp\u003eDo not let the reacted sample stand for too long after reagent is added, or accuracy will be lost.\u003c\/p\u003e \u003cp\u003eAfter the reading, it is important to discard the sample immediately, otherwise the glass might become permanently stained.\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640096629109,"sku":"HI-93701-03","price":100.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/300-x-free-chlorine-reagent-pre-crushed-tablet-powder-in-easy-t.jpg?v=1791581200","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-93701-03-free-chlorine-reagent-dpd-method-300-tests","provider":"Test All Water","version":"1.0","type":"link"}
