The total ionic strength adjustment buffer (TISAB) ensures that the solution pH is between pH 5 and 8 and that the activity coefficient is constant. The TISAB solution also preferentially complexes with various metal ions, such as aluminium and iron, which tend to form complexes with fluoride ions. TISAB thus ensures that these metal ions do not interfere, permitting an accurate total fluoride measurement. Measuring all solutions with a constant pH and ionic strength reduces the margin of error between measurements.

They also produce little heat, which could otherwise affect electronic stability.\u003c\/p\u003e\n\u003ch3\u003eHigh Quality Filters:\u003c\/h3\u003e\n\u003cp\u003eImproved optical filters ensure greater wavelength accuracy and allow a brighter, stronger signal to be received. The end result is higher measurement stability and less wavelength error.\u003c\/p\u003e\n\u003ch3\u003eGreater Light Yield:\u003c\/h3\u003e\n\u003cp\u003eA focusing lens collects all of the light that exits the cuvette, eliminating errors from imperfections and scratches that may be present in the glass. The use of the convex lens reduces the need for indexing cuvettes.\u003c\/p\u003e\n\u003ch3\u003eCAL Check Functionality:\u003c\/h3\u003e\n\u003cp\u003eHanna’s exclusive CAL Check feature allows for performance verification and calibration of the meter using NIST traceable standards. Our CAL Check standard vials are developed to simulate a specific absorbance value at each wavelength to verify the accuracy of subsequent readings.\u003c\/p\u003e\n\u003ch3\u003eMultiple Measurement Methods:\u003c\/h3\u003e\n\u003cp\u003eUsers can select the use of powder reagents supplied in packets or the use of low cost liquid reagents supplied in a dropper bottle.\u003c\/p\u003e\n\u003ch3\u003eBuilt-in Reaction Timer:\u003c\/h3\u003e\n\u003cp\u003eWaiting the proper reaction time is of key importance when performing colorimetric measurements. The countdown timer displays the time remaining until a measurement will be taken, ensuring consistent results between sample measurements and users.\u003c\/p\u003e\n\u003ch3\u003eLarge Cuvette Size:\u003c\/h3\u003e\n\u003cp\u003eThe sample cell of the HI-97711 fits a round, glass cuvette with a 25 mm path length. The relatively long path length of the sample cuvette allows the light to pass through more of the sample solution, ensuring accurate measurements even in low absorbance samples.\u003c\/p\u003e\n\u003ch3\u003eIntuitive Dot Matrix Display:\u003c\/h3\u003e\n\u003cp\u003eDesigned with a backlit graphic LCD, plus virtual keys, a battery status indicator, and error messages. Users will find the meter interface intuitive and easy to read. A dedicated help key provides information relating to the current meter operation, and can be used at any stage in the setup or measurement process to show contextual help.\u003c\/p\u003e\n\u003ch3\u003eAuto-off Protection:\u003c\/h3\u003e\n\u003cp\u003eThe meter uses three common AA batteries that allow for about 800 measurements to be taken. The auto-off feature automatically shuts off the meter after 15 minutes of inactivity in order conserve battery life.\u003c\/p\u003e\n\u003ch3\u003eAbout Chlorine\u003c\/h3\u003e\n\u003cp\u003eChlorine is a common chemical used by many due to is disinfection, oxidation and bleaching properties.\u003c\/p\u003e\n\u003cp\u003eIn swimming pools, drinking water and food processing, chlorine is used to disinfect and keep bacteria from growing. In metal finishing, it is used as an oxidiser to convert cyanide in wastewater to cyanate.\u003c\/p\u003e\n\u003cp\u003eIn the pulp and paper industry, it is used to bleach wood pulp so that paper is white. The HI-97711 is designed to measure low levels of free and total chlorine in water up to 5.00 mg\/L (ppm).\u003c\/p\u003e\n\u003ch3\u003eAdvanced optical system\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLED that generates very little heat.\u003c\/li\u003e\n\u003cli\u003e8 nm narrowband interference filter that is accurate to +\/- 1 nm and offers 25% increase in light efficiency.\u003c\/li\u003e\n\u003cli\u003eReference detector that modulates the voltage to LED for consistent light output.\u003c\/li\u003e\n\u003cli\u003eA concave focusing lens that reduces errors from imperfections in the cuvette.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAlso available as a kit: HI-97711C Free \u0026amp; Total Chlorine Portable Photometer Kit\u003c\/h3\u003e\n\u003cp\u003eThe HI-97711C kit is supplied with a meter, CAL Check standards, cuvettes (2), caps (2), plastic inserts for cuvettes (2), scissors, a cuvette cleaning cloth, 1.5V AA batteries (3), instruction manual, and an instrument quality certificate.\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Photometer Only","offer_id":43702839738626,"sku":"HI-97711","price":502.46,"currency_code":"GBP","in_stock":true},{"title":"Photometer Plus Case","offer_id":43702839771394,"sku":"HI-97711C","price":736.54,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/products\/hi-97711-free-and-total-chlorine-portable-photometer.jpg?v=1680197791"}],"url":"https:\/\/testallwater.co.uk\/collections\/water-quality-and-purity-testing.oembed","provider":"Test All Water","version":"1.0","type":"link"}
