GAS111L Methanol Gastec Detector Tubes 20 – 1000ppm

GAS111L Methanol 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.

Frequently Asked Questions

Q. When using tube GAS111L for determination of Methanol,  it turns entirely to yellow, which gas may be interfering with the reading?

A. When GAS111L is measured in condition of high humidity, the detecting layer of GAS111L turns to yellow. However, if some pale blue is found in the detecting layer, you can read the line as the concentration for methanol.

In this case, GAS111L turned entirely to yellow, this result means that there is no methanol between 20ppm – 1000ppm.
