t; Item: XL00105 The decoration and construction content: material purchasing Product Name: high negative pressure sampler Product model: FW--2 type Use: FW-2 type high negative pressure gas holder. It is a special tool for gas gas sampling in gas pipeline. Technical parameters: 1. Negative pressure of gas: 0-85KPa 2, weight: 1.3Kg 3. capacity: 100ml 4. full length: 320mm 5. diameter (coarse): 40mm Use method: before sampling, the suction end is connected with the gas intake on the gas pipeline, and the exhaust end is connected with the gas detector (or the sampling bag). When the gas sample is drawn, the piston rod is pulled, the one-way valve in the suction end is opened, the gas in the pipe is sucked into the gas cylinder, and then the piston rod is pushed forward quickly, the one-way valve in the exhaust port is opened, and the gas in the gas cylinder is sent into the gas detector (or sampling bag). By repeating several times, gas can be extracted into a gas detector (or a sampling bag). Use note: 1. Before use, check whether the plug valve is sealed. If there is a broken leak, replace it in time. 2, the latex tube on the core valve should be basically equal to the length of the copper core 3. The piston and the cylinder are lubricated regularly to prevent corrosion. -->
