If your facility incorporates a laminar flow cleanroom, these MAGNEHELIC and PHOTOHELIC differential pressure gauges can help you maintain the positive pressure necessary to block inrushing contaminants that can damage sensitive materials and operations.
The definition of life-history patter is: an organism's pattern of reproduction; may be rapid or slow (short or long).ong (short) life-history patterns are large species that live in more stable environments that usually have slow life-history patterns.
