Gastec manufactures the GV-100-S-TR and GV-110-S-TR Air Sampling Pumps. These pumps uses Gastec tubes to detect and quantify a large number of gases and gaseous compounds. The information provided here is not a complete documentation of the GV-100-S-TR or GV-100-S-TR pumps. If you need more information, call Western Safety Products. (updated 2008)
GV-100-S-TR Sampling Pump
This is the Gastec GV-100-S-TR Air Sampling Pump, shown with a detector tube in place
GV-110-S-TR Sampling Pump
This is the Gastec GV-110-S-TR Air Sampling Pump. This pump features an automatic pump stroke counter (shown as a yellow band with numerals).
There are quite a few add-ons and adapters available. A couple are shown here. Call Western Safety Products for more information.
One hand adapter
The picture above shows the optional one-hand adapter that allows sampling without having to pull the pump handle. This is useful in tight spots and where it would be difficult to use both hands to operate the sampler. After the adapter has been installed, the operator merely needs to push the sampler button and the pump will take a sample without having to pull the pump handle.
External hoses with pump
Shown above are 5 and 10 meter extension hoses for the gastec pump. Other available add-ons and adapters include telescoping extension poles, hot probe extensions, a pyrolizer unit, and more. Call Western Safety for more information on these and other additional components for the Gastec system.

tube intructions 2
When the end of color change is slanted, read the value in the middle of the slant, here 5%

tube instructions 3
When the color change is pale, read the value in the middle between the end of the dark layer
and the end of the pale layer. Here, the correct reading would be 5%
