Ze wordt gebruikt om de pH-elektrodes en controllers in het Hanna Instruments meet- en doseerassortiment te kalibreren, inclusief handmeters en paneelgemonteerde zwembadcontrollers. Een neutraalpuntbuffer zoals deze is het startpunt van elke standaard tweepuntskalibratie van pH.<\/p>\n<h3>Waarvoor het geschikt is<\/h3>\n<p>De oplossing werkt met elke pH-elektrode of meter die een standaardbuffer accepteert, inclusief Hanna Instruments draagbare testers, BL-seriecontrollers en paneelgemonteerde pH\/ORP-systemen voor zwembaden. Het is een algemene pH 7.01 buffer en is niet gebonden aan \u00e9\u00e9n specifiek instrumentmodel. Gebruik ze samen met een tweede buffer, meestal pH 4.01 of pH 10.01, voor een volledige tweepuntskalibratie.<\/p>\n<h3>Gebruiksaanwijzing<\/h3>\n<p>Spoel de elektrode met zuiver water, giet dan een kleine hoeveelheid buffer in een propere beker in plaats van de sonde in de fles te dompelen. Dompel de sondepunt onder, laat de meetwaarde stabiliseren en bevestig het kalibratiepunt op de meter of controller. Gooi het gebruikte deel na kalibratie weg om besmetting van de resterende voorraad te vermijden.<\/p>\n<h3>Shelf life<\/h3>\n<p>Houd de fles goed gesloten en bewaar ze op kamertemperatuur, weg van direct zonlicht. Een ongeopende fles heeft een lange houdbaarheid, maar eenmaal geopend moet de buffer binnen enkele maanden gebruikt worden omdat opgenomen koolstofdioxide en luchtvervuiling de pH-waarde geleidelijk doen verschuiven. Vervang de fles als de vloeistof troebel of verkleurd wordt of zichtbare groei vertoont.<\/p>\n<h3>Opmerkingen bij het bestellen<\/h3>\n<p>Geleverd als een enkele fles van 500 ml; andere bufferwaarden en elektrode-bewaar- of reinigingsoplossingen worden apart besteld. Voor routinematig zwembadonderhoud kalibreer je minstens maandelijks en houd je zowel een 7.01 als een tweede bufferwaarde op voorraad. Grotere sites houden vaak reservenflessen bij de hand zodat kalibratie nooit vertraging oploopt.<\/p>","protected":false},"excerpt":{"rendered":"<p>Hanna Instruments pH 7.01 calibration buffer solution, 500 ml bottle (HI7007L) HI7007L is a ready-to-use pH 7.01 calibration buffer solution supplied in a 500 ml bottle.
