laser oxygen analyzer

It is applied in the synthesis of methane-rich gas with hydrocarbon (Light oil, naphtha, LPG, light hydrocarbon, hydrocarbon-containing dry gas etc.) and steam as raw materials. The resulted gas can be further used to produce hydrogen, syngas with different CO/H2 ratio (for the synthesis of methanol or ammonia etc.) and coal gas.

Product Details

summary
The laser gas analyzer employs tunable diode laser absorption spectroscopy (TDLAS) to detect gases including O2, NH3, CH4,CO, CO2, HF, and HCl.
This system enables continuous, rapid, and precise detection of multiple gas concentrations. Compared with similar products, it features high stability, reliability, and selectivity. The device employs a counter-illumination principle.
product superiority
●The laser absorption spectrometer is based on the principle of laser absorption spectroscopy, and the gas cell is inserted into the chamber. It is easy to install and has a fast response speed.
●The inner lens is coated with a corrosion-resistant medium film, which has strong corrosion resistance.
●The explosion-proof design can be installed in the explosion environment.
●Multiple signal outputs, RS485 communication interface, and various wiring configurations(supporting up to 24~20mA outputs).
●Smart self-check with automatic fault alarm.
●LCD high-definition display with Chinese menu and infrared remote control.
●The infrared remote control is easy to operate.
