SP 19 On-line monitoring system for ammonia escape
SP 19 On-line monitoring system for ammonia escape is an honorary product of our company. The system consists of three parts: pretreatment system, gas analyzer and data processing and display. The installation mode is high temperature heat tracing extraction.
The instrument adopts tunable semiconductor laser absorption spectroscopy technology. When a laser beam with a specific wavelength is emitted by a semiconductor laser for absorption, the laser beam passes through the measurement.
