Style size: (178±10)mm × (330±10)mm
Operation steps:
Adjust the height of the funnel to a distance of 610±10mm between the center of the nozzle and the center of the 45° slope. Weigh the standard absorbent paper and clamp it on the 45° slope. Take a standard size sample and cover it on the standard absorbent paper and clamp it with a clip. Clamp the lower end of the sample with another clamp and hang the weight. The weight of the clamp and weight is 450 grams. Use a 500ml measuring cup to measure 500ml of distilled water and pour it into the funnel. After all the liquid has leaked out, remove the sample as soon as possible. and standard absorbent paper, and weigh the absorbent paper again for evaluation.
