Specification of COD Certified Standards And Reagents
HI93754 COD Certified Standards and Reagents
Each box of 25 bottles comes with a Hanna quality certificate. Reagents can be traced to NIST SRM® 930.
Accurate and repeatable measurements
Hanna COD's reagent was developed according to Standard Method 5220D, USEPA 410.4 and ISO 15705:2002 method.
Pre-dose bottle
The Hanna bottle contains approximately 3 mL of pre-dose reagent. The operator only needs to add a small number of samples.
Fast and accurate measurement
With pre-dose vials, test preparation time is dramatically reduced. There are no time-consuming reagent preparation or glass cleaning procedures.
Safe reagent
Hanna COD reagents are safe for operators and the environment. Bottles and caps have been designed to avoid accidental spillage of reagents. Due to pre-dose reagents, chemical quantities and handling time are minimized.

Notes:
* Methods with chromium-sulfuric acid are officially recognized by the EPA for wastewater analysis.
** This method is recommended for general purpose analysis without chloride interference.
*** The method follows the official ISO 15705 method. The ISO MR COD method is 0-1000 mg/L. The meter can read up.
