Let me introduce you how to choose the corresponding anti-blocking air pressure sampler.
The first choice of anti-blocking sampler is according to the material selection. For conventional ventilation pipes or wind pipes, only carbon steel (spray), ordinary stainless steel "target=_blank> stainless steel, 304 stainless steel" target=_blank>stainless steel It can be used because it is only required to face the loss of the inside of the rainwater in comparison with the conventional environment. The above three materials can meet the conditions of use, and the medium measured for the desulfurization and off-selling industry is highly corrosive. Most of them are made of 316 or better 2205 material. The reason is very simple. 316 material is not good quality, and the wall thickness is generally ≥3mm, which can effectively face the harsh measurement environment. 2205 is a stainless steel "target=_blank> stainless steel with better material than 316, so it has better corrosion resistance.
The second option is to follow the installation conditions. There are pipes on the upper and lower sides that cannot be installed vertically. The outlet pipe can be installed at the lower end of the anti-blocking sampler to show multi-angle mode, and the anti-blocking sampler can be installed vertically.
The third is according to the specifications and models, as shown in the following figure, which are 13 common models on the market.

The fourth is according to the length, the entrance of the anti-blocking sampler, that is, the welding port at the bottom, has a normal length of about 120 mm. The environment with insufficient installation conditions can choose to extend the length of the bottom welding port.
The fifth is according to the size of the shouting interface. The most used size is the 38-port welding port. Of course, 42 or other specifications can be used as required.
The last one is not particularly important. The pressure port (where the instrument tube is connected) is divided into 14*2 straight-through shouting interface and 20*1.5-14*2 active interface. The active interface is connected with a 14*2 shouting interface with a 20*1.5 thread and an anti-blocking air pressure sampler. The biggest feature is that the installation is convenient, and the next replacement is not necessary to weld 20*1.5. The thread can be tapped and replaced with another new anti-blocking air pressure sampler (the length of the specification needs to be the same as before) for measurement.
The above information is how to choose the anti-blocking air pressure sampler. If you are interested in the information about the anti-blocking air pressure sampler, please feel free to ask us.
