Ideal for selecting masks and verifying/instructing proper mask wearing!
The mask fitting tester is a portable type of tester that quantitatively checks the fit of dust masks on the face in various work environments and medical settings within one minute. It is effective for preventing dust exposure in occupational health settings and for air and droplet infection control in medical environments. With a single detector (particle counter), it automatically switches between measuring the particle count inside the mask and outside (in the room) for continuous measurement. This reduces errors caused by differences in the characteristics of the detectors. 【Features】 - Measures the fit of dust masks on the face - Can measure without modifying the mask - Capable of measuring N95 respirators (N95 masks) - Includes a heating tube to prevent condensation of water vapor in exhaled breath, which can lead to droplet formation - Equipped with RS-232C output function for measurement data For more details, please contact us.
