Hanna Instruments® COD reagents are available in several formats. Each box of 25 vials is supplied with a Hanna Instruments® certificate of quality. The reagents are traceable to NIST SRM® 930. Three measurement ranges to satisfy each need:Low range (LR): 0 to 150 mg/L O2Medium range (MR): 0 to 1500 mg/L or 0 to 1000 mg/L O2High range (HR): 0 to 15000 mg/L O2Accurate and repeatable measurements: These reagents have been developed in accordance with Standard Methods 5220D, US EPA 410.4 and ISO15705:2002 methods. Pre dosed vials: Each vial contains approximately 3 mL of pre-dosed reagent. The operator just needs to add a small quantity of the sample - 2 mL for LR and MR, and 0.2 mL for HR analysis. Quick and accurate measurements: Time is dramatically reduced when using pre-dosed vial tests. There is no time consuming reagent preparation procedure or glassware cleaning. Safe reagents: These COD reagents are safe for operators and the environment. Vials and caps have been designed to avoid accidental reagent spills. Thanks to the pre-dosed reagents, the amount of chemicals is minimized.
Hanna Instruments® also produces mercury free reagents to be used for analyzing samples without chlorine.
