Short-Term Gas and Vapour Measurement with Spot Sampling Pump
GASTEC short-term gas detector tubes are used with a GASTEC manual spot sampling pump for rapid on-site measurement of target gases or vapours. In this A–Z list, where the same physical tube can measure multiple chemicals, it is consolidated under a single tube code without duplication.
Shelf life is a nominal duration, not the remaining life of the supplied lot. The expiry date and storage conditions on the box take precedence. Storage temperature is separate from measurement temperature. If no refrigeration note is shown here, check the current instructions; absence of a note does not mean refrigeration is unnecessary.

GASTEC Direct-Reading Gas Detector Tubes
GASTEC direct-reading detector tubes are used in conjunction with a GASTEC manual direct-reading gas sampling pump to rapidly determine the concentration of target gases or vapours on site based on the colour-change principle. Appropriate tube selection must be made according to the target chemical, expected concentration, and the number of pump strokes specified in the catalogue.
