An intrinsically safe, manually operated gas sampling system that utilizes colorimetric detector tubes and a precision piston pump. It is capable of measuring over 500 different gases and vapors without the need for batteries or electrical power.
The Gastec system works on a simple 3-step principle: Break, Insert, and Pull. A glass detector tube, filled with a specific chemical reagent, is inserted into the GV-100 or GV-110 sampling pump. As the pump handle is pulled, a vacuum draws a precise volume of air through the tube. The reagent reacts with the target gas, creating a color stain whose length corresponds to the gas concentration.
Although, technology is always evolving, one demand on our products never changes: the demand for customer safety. Whenever we contribute to customer safety, we are presented with an opportunity to develop further.
GASTEC holds this corporate creed of safety and development in high esteem, as it strives to grow while always putting customer safety first.
