Air Velocity Range<\/h3>\n\n\n\n<p>Low speed (0.1 m\/s) requires thermal type.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Environment<\/h3>\n\n\n\n<p>Dusty? Avoid hot wire.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Accuracy Requirement<\/h3>\n\n\n\n<p>Regulatory audit? Choose calibrated digital instrument.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Portability<\/h3>\n\n\n\n<p>Field inspection requires handheld device.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Budget<\/h3>\n\n\n\n<p>Basic vane models are affordable. Ultrasonic systems are premium.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Why Air Movement Measurement Is Critical for Workplace Safety<\/h1>\n\n\n\n<p>In industrial safety management, airflow measurement ensures:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Removal of hazardous fumes<\/li>\n\n\n\n<li>Control of combustible dust<\/li>\n\n\n\n<li>Adequate oxygen levels<\/li>\n\n\n\n<li>Compliance with ventilation standards<\/li>\n\n\n\n<li>Thermal comfort<\/li>\n<\/ul>\n\n\n\n<p>Improper ventilation can lead to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Heat stress<\/li>\n\n\n\n<li>Chemical exposure<\/li>\n\n\n\n<li>Respiratory hazards<\/li>\n\n\n\n<li>Explosion risk<\/li>\n<\/ul>\n\n\n\n<p>As a
