They are commonly used during cleanroom classification to verify particle levels in different zones or to average particle counts across multiple spots. In cleanroom classification they are ideal for sampling smaller particles in ISO environments of ISO 6 and above. They serve as excellent tools for confirming proper operation when a facility already has a fixed network of remote counters. This makes handhelds perfect for quickly pinpointing contamination sources or verifying maintenance effectiveness.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e7f1149 elementor-widget elementor-widget-image\" data-id=\"e7f1149\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"624\" height=\"416\" src=\"https:\/\/www.golighthouse.com\/en\/wp-content\/uploads\/2025\/10\/hh-blog-1.png\" class=\"attachment-large size-large wp-image-30439\" alt=\"\" srcset=\"https:\/\/www.golighthouse.com\/en\/wp-content\/uploads\/2025\/10\/hh-blog-1.png 624w, https:\/\/www.golighthouse.com\/en\/wp-content\/uploads\/2025\/10\/hh-blog-1-300x200.png 300w\" sizes=\"(max-width: 624px) 100vw, 624px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6c7b713 elementor-widget elementor-widget-text-editor\" data-id=\"6c7b713\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Although handhelds don\u2019t match the sample volume times of larger units, they are prized for their agility.
