HI-94754C-25 COD Reagents, High Range EPA approved Dichromate Method with Bar Code information

Hanna's extended description

The HI-94754C-25 is a box of 25 reagent vials for COD, high range. This reagent vial is bar coded with specific reagent information that is automatically scanned.

High range: 0 to 15000 mg/L (as O₂).

*This reagent uses the Dichromate method

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.

About the testing methods

Dichromate EPA - Method with chromium-sulphuric acid is officially recognised by EPA for wastewater analysis.

Dichromate mercury-free - This method is recommended for general purpose analysis with no chloride interference.

Dichromate ISO - Method follows the official method ISO 15705. COD MR ISO method is 0 – 1000 mg/L. Meter can read higher.
