The <strong>C-21 VOC Sensor<\/strong> is a rugged, easy-to-use gas monitor designed to <strong>detect volatile organic compounds (VOCs)<\/strong>\u2014helping you identify leaks, poor air quality, and potential health hazards before they become serious problems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Whether you\u2019re in a workshop, lab, industrial facility, or dry cleaning operation, the C-21 offers <strong>real-time, on-the-spot protection<\/strong> with minimal setup and maintenance.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Versatile and User-Friendly Monitoring<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The C-21 is designed with both portability and fixed-installation flexibility in mind:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Handheld operation<\/strong> with a built-in rechargeable battery<\/li>\n\n\n\n<li><strong>Wall-mounted use<\/strong> with an included magnetic strip and audible alarm<\/li>\n\n\n\n<li><strong>AC adapter<\/strong> included for continuous power<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Because of its self-contained design, the C-21 requires no special training or installation. It\u2019s ideal for non-technical users and professionals alike.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Detects a Wide Range of Common VOCs<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The C-21 is especially sensitive to solvent vapors, making it ideal for environments using:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Paint thinners<\/li>\n\n\n\n<li>Dry cleaning fluids<\/li>\n\n\n\n<li>Cleaning solvents<\/li>\n\n\n\n<li>Gasoline vapors<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">It does not respond to carbon dioxide or radon and has only a minimal response to carbon monoxide, keeping its readings focused on the most common VOC threats.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Reliable Detection You Can Trust<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">With high sensitivity and low detection thresholds, the C-21 detects VOCs well below OSHA Threshold Limit Values (TLVs). A bright, color-coded display (green\/yellow\/red) shows gas concentration at a glance, and the internal audible alarm warns users when dangerous levels are reached.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Example VOC Detection Limits:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>VOC Gas<\/th><th>Lower Limit<\/th><th>Alarm Threshold<\/th><th>TLV<\/th><\/tr><\/thead><tbody><tr><td>Acetone<\/td><td>4\u20135 ppm<\/td><td>20\u201325 ppm<\/td><td>750 ppm<\/td><\/tr><tr><td>Benzene<\/td><td>5\u201310 ppm<\/td><td>25\u201350 ppm<\/td><td>10 ppm<\/td><\/tr><tr><td>Formaldehyde<\/td><td>1\u20135 ppm<\/td><td>15\u201325 ppm<\/td><td>0.1 ppm<\/td><\/tr><tr><td>Toluene<\/td><td>3\u20135 ppm<\/td><td>15\u201325 ppm<\/td><td>50 ppm<\/td><\/tr><tr><td>Trichloroethylene<\/td><td>10\u201320 ppm<\/td><td>50\u2013100 ppm<\/td><td>50 ppm<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Note: TLV is the recommended exposure limit for repeated worker exposure as defined by OSHA and other health agencies.<\/em><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Built-In Control Capabilities<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The C-21 isn\u2019t just a detector\u2014it\u2019s a controller.
