Product Number: TNT815
Expert COD test made simple.
For saline COD samples with Chloride concentrations up to 20,000 mg/L Cl-!
COD TNTplus® chemistry and your Hach spectrophotometer are engineered to simplify water analysis for accurate results, everytime. For photometric determination of low range COD by the reactor digestion method.
High Chloride concentrations usually interfere COD testing and lead to a high bias. Samples with low COD cannot simply be diluted since the COD detection limit is crucial. TNT815 is a safe, reliable and very easy to use method for the photometric detection of low range COD in saltwater samples, e.g. in seawater. The Direct Read Technology will provide your COD result to the nearest mg/L! No more cleaning glassware and dealing with large amounts of hazardous reagents and waste. Ideal to combine with our ezCOD recycling service!
25 COD vials per box.
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!
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.
The 2D vial 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.
