Features
- 01 It adopts imported cold light source, with good optical performance and stable and accurate test.
- 02 The precise quantification of trace reagents is achieved by using a sophisticated infrared quantification system.
- 03 The precise quantification of trace reagents greatly reduces the amount of reagents used.
- 04 The peristaltic pump uses negative pressure to inhale, avoiding corrosion of the pump tube and making reagent mixing simpler and more flexible.
- 05 Peristaltic pump negative pressure suction to avoid corrosion of pump tube
- 06 Imported modified polytetrafluoroethylene transparent hose with a diameter greater than 1.5mm is used to reduce the chance of blockage by water sample particles.
- 07 Support RS232, RS485, 4-20mA data transmission.
- 08 The ammonia nitrogen monitor has multiple measurement modes (continuous sampling, periodic sampling) for customers to choose from.
- 09 The cleaning waste liquid of the ammonia nitrogen monitor is separated from the reaction waste liquid, which is convenient for waste liquid treatment.
- 10 When the ammonia nitrogen monitor is operating normally, there is no workload except adding reagents and standards.
- 11 The ammonia nitrogen monitor uses a high-resolution LCD display module, and all data, status and operation prompts are displayed in Chinese.
working principle
Working principle of ammonia nitrogen monitor TP1112
Ammonia nitrogen monitor TP1112 is an online water quality monitor . After the water sample and masking agent are mixed, ammonia nitrogen in the form of free ammonia or ammonium ions reacts with salicylic acid colorimetric reagent in an alkaline environment and in the presence of a sensitizer to generate a colored complex. The analyzer detects the color change and converts the change into an ammonia nitrogen value for output. The amount of colored complex generated is equivalent to the ammonia nitrogen content.
