Hach's Simplified TKN (s-TKN^TM) contains everything needed to measure TKN in one box. The s-TKN Method uses TNTplus^TM technology, offering safer pre-measured chemistries that work exclusively with the Hach DR Family of Spectrophotometers (DR 2800^TM, DR 3800^TM, and DR 5000^TM). The chemistry vials require no preparation or glassware (no cleanup!) and enable the spectrophotometer to automatically recognize the testing method, eliminating the need to pre-program or create calibration curves. No blank is required, further reducing expense.

The s-TKN system:

• Eliminates the use of hazardous mercury
• Provides simultaneous results for Total Nitrogen, Nitrate + Nitrite, and TKN
• Reduces operating expenses with costs under $4 per test - this represents an annual savings of over $550 compared to outsourcing TKN on a monthly basis
• Minimizes training and equipment requirements by offering a test that anyone can perform
• Takes ~ 1 hour total analysis time with minimal hands-on time

Note: A DRB 200 reactor with 20 mm holes is required for the s-TKN digestion
