21259-25，COD預(yù)制試劑0-1500mg/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(jiǎn)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.
