Product details
Hach TNTplus Vial Tests
TNTplus are ready-to-use reagent vials. Each vial carries a barcode that tells a compatible Hach spectrophotometer which test it is, its batch and its expiry date, so the method is selected automatically and expired reagents are flagged. Batch-matched calibration data means no reagent blank is needed for most tests.
