Product Principle:
Mvuramuenzaniso, potassium dichromate digestion solution, silver sulfate solution (silver sulfate secatalyst yekubatanidza inogona kunyatsoita straight-chain fatty compound oxide) uye sulfuric acid musanganiswa inopisa kusvika 175 ℃, dichromate ion oxide solution ye organic matter mushure mekushanduka kweruvara, analyzer kuona shanduko yeruvara, uyeBODkukosha kwekubuda uye kushandiswa kwedichromate ion yemukati yeoxidizable organic matter quantity.
