21258-25，COD預(yù)制試劑0-150mg/L的特點(diǎn)：

·  符合EPA標(biāo)準(zhǔn) EPA Approved：
Low Range （LR） and High Range （HR） vials are  approved by the USEPA for reporting of wastewater COD concentrations.
· 操作簡單、安全 Simpler and  Safer
Prepared COD reagents eliminate the need for  measurement of corrosive    and toxic chemicals. Just add sample to the COD vial,  digest and    measure. Photometric measurements provide accurate results without  the    equipment and effort required for titrations.
· 廢液極易處理 Easy Disposal
Small reagent  volumes used in Hach COD vials minimize the volume of    spent silver, mercury and  chromium waste. Customers in the contiguous    48 United States benefit from the  availability of the ezCOD waste    recycling program, which provides comprehensive  transportation and    disposal of COD vials.
