Gas Masks A close-fitting seal between a gas mask and the contours of a person's face and head is essential to keep unwanted chemicals from being inhaled. The interface pressure must be very light, or the wearer will reject the mask as uncomfortable. The size, shape, and contours of individual faces vary over a significant range, and there is the added complexity of facial and scalp hair. Measurement of sealing pressure of candidate designs is accomplished with paper-thin, flexible sensors that fit between the mask and skin without disrupting the fit.
The sensors have high sensitivity and cover a distance both along the seal and across it with an array of active elements so pressure distribution can be mapped. I-Scan software provides vivid displays and facilitates comparisons between designs and during simulated operating conditions. With the help of Tekscan's highly qualified sales and engineering support team, each system may be configured to meet your specific needs.
