Full Description Specification

The HI-93754G-25 is a box of 25 reagent vials for COD, medium range ISO

*This method follows the official method ISO 15705

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.

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.
