Enables flexible reagent sampling timing and diverse channel configurations while minimizing dead volume for easy maintenance and extended service life.
Utilizes visual photoelectric system for precise reagent measurement with 0.7 mL per dose, eliminating quantitative errors and significantly reducing reagent usage.
Employs peristaltic pump with negative pressure suction, creating an air buffer zone between reagents and pump tube to prevent corrosion.
Operates under high-temperature and high-pressure conditions to accelerate reactions while eliminating corrosion risks from volatile gases.
Uses imported modified PTFE transparent tubing with inner diameter >1.5 mm to minimize clogging by particulate matter.
After water sample mixing with masking agent, ammonia nitrogen reacts with salicylic acid chromogenic reagent under alkaline conditions, forming a colored complex. The analyzer detects this color change and converts it into precise ammonia nitrogen concentration values.
- Data retention during abnormal alarms or power outages
- Touchscreen display and command input interface
- Automatic discharge of residual reactants and system resumption after power restoration
- Lower failure rates and reduced maintenance requirements compared to similar products
