pH-indikatorstrips
pH-indikatorstrimler måler fosfatindholdsniveauer gennem hurtige kolorimetriske reaktioner. Smalle, mellemliggende eller universelle områder er klar til øjeblikkelig kvantitativ testning og har forskellige graderede intervaller for nøjagtige vurderinger. Efter at have dyppet pH-indikatorstrimler i opløsninger og prøver skal du blot matche den fremkomne farve med de medfølgende diagrammer. Kompakte lakmuspapirtest kan medbringes i marken til test på stedet ud over laboratorietest.
