This system contains two primary parts: the process analysis instrument, and the sampling pretreatment device, and an overall structure of 5 parts: sample gas acquisition unit, sample gas pretreatment unit, calibration unit of analytical instrument, process analysis instrument and measurement and control unit.

Features
1. The sampling probe requires no maintenance, is corrosion resistant, wear resistant, block resistant, and offers multi-probe alternative sampling and continuous analysis.
2. The solenoid valve is controlled by PLC, and the filter element of the sampling probe is regularly blown back by compressed air.
3. A new dry sampling technology will reduce the probability of blocking the sampling pipeline and avoid the loss of soluble components in process gas（Process Gas）.
4. Multiple filters can remove dust, tar, water and sulfide.
5. Uses rapid condensation measures to reduce the loss of soluble gas components.
6. The sample gas pipeline is made of high-quality stainless steel and is equipped with a double-clamp sleeve joint. Great air tightness, long service life and strong corrosion resistance.
7. Automatic continuous sampling and processing, low maintenance cost.
8. After the sampling process gas enters the pretreatment system, some of it will be discharged, thus improving the gas flow rate in the sampling pipe, and reducing analysis lag time caused by a long pipe.
9. The sampling pipe is made of a corrosion resistant material with heating and temperature control functions. In requested cases, the heaters and temperature controllers are explosion resistant.
10.FCS and PLC automatic control. Automatic control functions such as automatic patrol inspection, automatic drainage, automatic alarm, self-diagnosis, automatic fault treatment and safety interlocking.
