Detector Tubes offer rapid, point-in-time chemical analysis of hazardous gases using glass tubes coated with reactive reagents. When a target gas reacts, a distinct color change appears along the length of the tube, indicating concentration levels. These handheld devices provide accurate, on-the-spot detection for confined space inspections, leak investigations, and routine safety checks. Detector Tubes enhance onboard safety, support compliance with regulations, and reduce operational risk through timely hazard identification.
