The Model T201 combines a specially configured chemiluminescence analyzer with an external thermal converter to give stable and repeatable NH3 measurements at very low levels. In addition, the T201 provides simultaneous values for NO, NO2, and NOx concentrations.

• Chemiluminescence technology with external thermal converter for stable, repeatable trace NH₃ measurements
• User-selectable ranges from 0-50 ppb to 0-2,000 ppb with independent ranges for NH₃, NO, NO₂, and NOx
• AutoZero valve corrects for zero noise while an innovative conditioned sample path minimizes interferents
• Large, vivid color graphics display with capacitive touch screen interface
• Adaptive signal filtering with temperature and pressure compensation
• Ethernet, RS-232, and optional USB communications with APIcom™ remote control software and comprehensive internal data logging
