HS-813 ammonia escape monitor
Main feature
1. High measurement accuracy, free from background gas cross interference.
2. The tunable diode laser absorption spectroscopy technique is used to measure the gas. The infrared tunable laser is used as the light source to emit a laser beam of a specific wavelength, pass through the gas to be tested, and convert the optical signal into an electrical signal through the receiving end of the detector. Analyze the laser light intensity attenuation caused by the absorption of the measured gas, and realize the self-sensitive and rapid and accurate monitoring of the gas concentration to be measured. Since the laser spectrum is particularly narrow (small τ at 0.001 nm) and emits only a specific wavelength absorbed by the gas to be measured, the measurement is not disturbed by other components in the measurement environment.
3, efficient anti-corrosion. The analysis method of the detachable bypass measurement adopts the whole process of high temperature heat tracing, which effectively ensures that the temperature of the corrosive sample gas is higher than the acid dew point, and the contact parts are protected from corrosion.
4. High reliability and economic operation (easy to operate and maintain). There are no moving parts inside the analyzer, and the unique system design for the industrial environment greatly enhances reliability. The analyzer has a friendly human-computer interaction interface, a large temperature LCD display, and a menu-like operation. The operation of the instrument can be mastered without the need for instructions. After pre-measurement measurement, the instrument has a long service life; convenient maintenance and low operating cost.
5, the system has no drift, avoiding the need for regular calibration. The HS-813DLGA series NH3 analyzer uses multiple reflections and long-range modulation spectroscopy techniques, and dynamically compensates to lock the gas absorption line in real time, independent of temperature, pressure and environmental changes, without drift. Flexible installation and commissioning
6, using 19" standard chassis, can be installed in the complete set of equipment, easy to install, boot can be normal operation without on-site optical path debugging. The analyzer is far away from the measurement point, making parameter debugging easier and more convenient.
Long-term reliable and stable data storage
7, support U disk storage, to ensure long-term reliable storage of data, you can arbitrarily query the historical data of the common segment at each time.
