Each Kitagawa Detector Tube is formulated with high purity reagents that absorb and react with the target gas or vapor being measured. A colorimetric stain is created that is proportional in length to the concentration. For most tubes, the concentration is read directly off the measurement scale on each tube.

Features Include:

• Calibrated for a Single Pump Stroke
• 300 Gases Available; from Acetaldehyde to Xylene, from ppm to percent
• Manufactured with Ultra-High Purity Reagents
• Narrow Diameter Tube Assures Sharp Endpoints (no oblique demarcation lines)
• Tubes Wrapped in a Thin Film that Guards Against Shattering and Dispersing of Reagent in case of Accidental Breakage
• Accuracy Between +/- 5% and +/- 15% Depending on the Tube

Measurement Range:

• Phosphine, 20-1400 ppm
• Phosphine, 0.25-20.0 ppm
• Phosphine, 100-3,200 ppm
• Phosphine, 200-6,000 ppm
