The HI-93754C-25 is a box of 25 reagent vials for COD, high range 0 to 15,000 mg/L (as O2) for use with the Hanna HI-83214-02 multiparameter COD meter and photometer *This method with chromium-sulphuric acid is officially recognised by EPA for wastewater analysis Each box of 25 vials is supplied with a Hanna certificate of quality. The reagents are traceable to NIST SRM® 930. Hanna offers reagents to cover three separate ranges. Three measurement ranges to satisfy every need ? As COD levels vary depending on the application and process measuring points. Simply choose the best range for the application: low range ? 0 to 150 mg/L O2, medium range ? 0 to 1500 mg/L O2 and high range: 0 to 15000 mg/L O2. Accurate and repeatable measurements ? Hanna COD reagents have been developed in accordance with Standard Methods 5220D, USEPA 410.4 and ISO 15705:2002 methods. Pre-dosed vials ? Hanna vials contain approximately 3mL of pre-dosed reagent. The operator just needs to add a small quantity of the sample. Quick and accurate measurements ? With pre-dosed vials, test preparation time is dramatically reduced. There is no time-consuming reagent preparation procedure or glassware cleaning. Safe reagents ? Hanna COD reagents are safe for operators and the environment. Vials and caps have been designed to avoid accidental reagent spills. Due to the pre-dosed reagents, the amount of chemicals and handling time is minimised.
