Chemical Oxygen Demand – Expert Ultra Low Range COD test made simple.
Recommended COD test for wastewater effluent.
The Chemical Oxygen Demand analysis provides important information for the water treatment process and is essential to calculate the BOD COD ratio in wastewater. Due to this, the COD is one of the most frequently analyzed wastewater parameters globally.
Why should you use Hach TNTplus® COD tests?
Hach TNTplus COD vial test reagents are incredibly simple to use and cut down significantly on waste generation compared to other COD test kits. TNT820 is based on Hach Method 10211 for virtually any type of water sample.
Hach TNTplus COD vial tests are available in multiple ranges. TNT820 provides a result in the Ultra Low Range of 1 – 60 mg/L COD and is often used for Chemical Oxygen Demand measurement in wastewater effluent. Hach TNT820 does not require a separate blanking vial for further waste reduction and is compatible with our ezCOD Waste Recycling Service for further peace of mind.

Benefits
Easy and safe handling
The innovative vial and reagent delivery makes tests easier to use than powder pillows or liquid reagents and significantly reduces spillage or contamination risk.
No reagent blank necessary
The high quality of TNTplus vials, tight reagent production controls, instrument calibration verification, and high instrument stability all combine to eliminate the need to run reagent blanks—saving you time and money!
Lot after lot – Be Right
Truecal™ with each vial includes the calibration data for each individual lot, reducing variation in results. This allows you to meet reporting standards and to perform proficiency testing with higher confidence.
Automatic method detection
New 2D barcode details batch number and expiry date of reagents, which are documented along with the measurement result. An automatic warning is issued if expiry date has passed. Certificate of Analysis (COA) is available on RFID tag on the box.
Documented shelf life and COA
New 2D barcode details batch number and expiry date of reagents, which are documented along with the measurement result. An automatic warning is issued if expiry date has passed. Lot specific information (COA) is available on RFID tag on the box.
