Air Flow Meters. Here you will find air flow meters to measure air velocity and air pressure. Depending on the type of application, air flow meters a re made as hot-wire air flow meters or pocket weather flow meters, both of which can measure air velocity and air pressure. The results of measuring the air velocity can be stored in memory of the device depending on the model.
Pores are a natural part of the skin; blackheads are the superficial plugs that may form within them. Pore dilatation begins with faulty exfoliation of cells lining the interior gland - cells are too sticky leading to microscopic plugs. Sebaceous glands continue to produce sebum that accumulates behind the plug. Protracted pooling of skin oils serves to nourish bacteria (like P. acnes and S. epidermidis). Blackheads and enlarged pores often go hand-in-hand. Blackheads can either expand pores or simply focus attention on them.
The age-old idea that you can shrink your poresâusing anything from a splash of ice-cold water to an egg-white maskâis a fantastic one. Sadly, itâs also a fantasy: âPore size is genetically determined,â says Debra Jaliman, a dermatologist in New York City, and you canât make pores physically smaller.
