Hach COD TNTplus Vial Test, LR, 3-150 mg/L COD , 150 Tests, TNT82106

Description

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. TNT821 is based on Hach Method 8000 for virtually any type of water sample. Method 8000 is USEPA approved for wastewater analysis under 40 CFR 136.3 and based on Standard Methods 5220 D. Hach TNTplus COD vial tests are available in multiple ranges. TNT821 provides a result in the Low Range of 3 - 150 mg/L COD and is often used for Chemical Oxygen Demand measurement in wastewater effluent. Hach TNT821 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.

Features

• The innovative vial and reagent delivery makes tests easier to use than powder pillows or liquid reagents and significantly reduces spillage or contamination risk.


• 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!


• 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.


• The bar-coded vials allow for automatic method detection and measurement by the spectrophotometer, considerably increasing the speed of analysis. Errors are reduced as instrument averages 10 readings and rejects outliers from scratched, flawed, or dirty glassware.


• 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.
