Ammonia nitrogen analyzer - product features of ammonia nitrogen water quality detector
  • Modular design, each component operates independently, which improves the working efficiency of the instrument 
  • Various types of signal output: printer, RS485/RS232, 4-20mA, GPRS, relay, etc. 
  • Various ways of making samples: manual control, timing (interval and whole point) control, 4-20mA current input control, switch control, and other forms 
  • Automatic compensation for measuring light source attenuation, good stability, and small drift 
  • Wide measuring range, fast sampling speed, and high precision 
  • Less pharmaceutical dosage, maintenance-free for one month 
  • Photoelectric non-contact metering, high metering degree, and high operational reliability 
  • Adopt a high-resolution industrial-grade color touch screen, friendly interface, configuration design, and simple operation.
