Larutan Buffer merupakan larutan yang bisa mempertahankan nilai pH meskipun ditambah sedikit asam, sedikit basa, atau sedikit air (pengenceran). Hal ini dikarenakan karena larutan Buffer mengandung zat terlarut bersifat “penyangga“ yang terdiri atas komponen asam dan basa.

Serbuk kalibrasi memungkinkan Anda menguji secara akurat dan cepat pH kolam, akuarium, air dengan alat penguji pH / meter Anda.Cara pemakaian (ada di belakang bungkus juga):1. Usahakan pengukuran dilakukan pada ruangan yang bersih dan bersuhu 25-30 C2. Buka bungkusan pH 4.01 dan tuangkan SELURUH isinya dalam gelas ukur berisi 250 ml air aquades (jangan aqua atau air minum apalagi air ledeng/air hujan). Jika ragu bisa beli di apotek bilang "Air Aquades" / "Distillated Water" atau di bengkel air aki yg botol biru.3. Aduk larutan hingga tercampur dengan sempurna.4. Masukkan PH Meter sampai batas pencelupan. Tunggu 1-2 menit.5. Ambil obeng kalibrasi dan putarlah lobang bagian belakang PH Meter sampai didapat angka 4.01 menyerupai nilai PH yg tertera di bagian depan bungkusan serbuk tadi.6. Bersihkan alat dan gelas, lalu ulangi kalibrasi utk bungkusan pH 6.86.
