GASTEC® Detection Tubes

Features

Extensive Gas Coverage: Monitor 500+ gases with over 200 tube options, including specialty formats like Polytec, dosimeter, injection, and CBA tubes.
Direct Scale Readings: Tubes are self-calibrated and marked with concentration scales, enabling immediate visual interpretation.
Accurate & Repeatable Sampling: Manual stroke pumps (GV‑100/GV‑110) offer 100 mL or half-stroke 50 mL accuracy verified by EN1231 leakage tests.
Intrinsically Safe & Portable: No batteries required, lightweight (pump ~245 g), suitable for hazardous-zone sampling.
Rapid Analysis: Response times range from seconds to minutes, with Polytec tubes enabling quick multi-gas profiling
Robust Safety Features: Dual-layer glass protection holds reagents in case of breakage; batch-tested with QC numbers for consistency .
