  • Page 7: About This Product

    2 About this Product Overview This measuring instrument checks the degree of adhesion when the user wears a respirator (disposable or replaceable type). Measurements can be performed in a general indoor space. Individuals have differently shaped faces. Many different types of respirators are sold by respirator manufacturers, so select a respirator that is a good fit to your face when it is worn.
  • Page 8 Quantification of the Degree of Adhesion of the Respirator  The method used to quantitatively assess the degree of adhesion between the respirator and the face of the person wearing the respirator is as follows. If there is a gap that particles can just pass through between the face of the wearer and the respirator, depending on the size of this gap, particles outside the respirator will penetrate inside the respirator during respiration.

  • Page 24: Checking The Particle Concentration In The Environmental Air

    Checking the Particle Concentration in the Environmental Air 3-6-3 For correct measurements, there must be a certain amount of particles in the environmental air. If there are too few particles during measurement, an alert will be displayed and the measurements will stop. (Regarding the minimum particle standards leading to the display of an alert, see p.43 for the Fit Check mode, and see p.44 for the other modes.) The particle concentration in the environmental air is checked as follows.

  • Page 25: Checking And Cleaning The Suction Ports

    Checking and Cleaning the Suction Ports 3-6-5 With extended use, or use in very dusty environments, contaminants can accumulate within the suction ports, reducing the intake of air, leading to an impact on the measurements. Check the interior of the suction ports periodically, and clean them if necessary (see p.60). As a diagnostic procedure, remove the sampling tube from the suction port, and switch repeatedly to the Fit Check mode (see p.36).
