Product Description


GAS10 Nitrogen Oxides (Separate Quantification) Standard Gastec Detector Tubes

Gas detector tubes are glass tubes that are filled with a chemical reagent that absorbs and reacts with the target gas or vapour being measured. Gastec tubes do not contain hazardous substances

A colorimetric stain (a colour change) is created. For most tubes, the concentration is read directly from the pinpoint accurate measurement scale on each tube.

The Gastec detector tube system is comprised of a handheld Gastec air sampling pump and Gastec detector tubes


Shelf Life - a1-cbiss will never dispatch detector tubes with less than 3 months remaining before expiry. a1-cbiss employ a stock rotation policy of first in, first out. Specific shelf life requirements must be identified at the point of order placement (use the comment box in the checkout process). The expiry date is printed clearly on the front of the detector tube packet.

Special Note

When used, connect the NO₂ and the NO tube (with both ends broken off). This twin tube can measure NO and NO₂ concentrations simultaneously. 



Q. According to the instruction manual for GAS10, we have to connect the NO tube and NO2 tube. Is it possible to use only NO2 tube without connecting NO tube? We want to measure only NO2. We know that pre-treatment tube must be used because it removes some substances.

A. An accurate result is not able to be acquired if you use only NO2 tube without connecting NO tube because air resistance is changed for the usage.
