• A personal sampler for personal exposure assessment of working environment dust.
• Using an inertial impingement type particle separator, dust is separated by the particle separation characteristics of PM4 (4 μm, 50% cut). Coarse particles of PM4 or higher are collected on the SUS collection plate, and PM4 particles are collected on the filter paper.
• It is possible to measure the dust exposure of individual workers from both the PM4 dust concentration and the total dust concentration.
• Uses suction pump MP-W5P type (CE marking product) with constant flow function and integrated flow function.
• Instantaneous flow rate and accumulated flow rate can be displayed as 25°C, 1 atmosphere equivalent.
• The NWPS-254 personal sampler holder is a type certified product of the Japan Working Environment Measurement Association.
• The mini pump MP-W5P type (CE marking product) has a belt hook on the back.
