DESCRIPTION
A detector tube system that performs measurements using the GV-100/GV-110 gas sampling pump. The handle on the gas sampling pump is pulled all the way back to create a vacuum inside the cylinder, drawing the gas sample through the detector tube. This can be used by anyone, anywhere, and at anytime to quickly and easily make an accurate concentration reading. GASTEC Detector Tubes indicate concentrations directly by way of a calibrated scale printed on the tubes. At GASTEC, we endeavor to achieve highest quality detector tubes for analyzing airborne gases/vapors, as well as pollutants in soil and water through our advanced state-of-the-art research and development. Through our efforts we have acquired a solid reputation among our customers in virtually all sectors of industry, commerce and society. Tubes are now available for more than 500 different applications.
Gas Detector Tube, Short Term, Detects: Hydrogen Sulphide (H2S), 12.5 to 25 ppm, 25 to 250 ppm, 250 to 500 ppm, Break-Off Tip, Glass, White to Brown

| Material | : | Glass |
| Color | : | White to Brown |
- High quality glass tube
- Calibration scale (in ppm, mg/m3, mg/l or % depending on the substance to be measured and its concentration)
- Printed in an ink that permits high legibility against the color change layer
- The scale is determined for each production lot that has passed Gastec's extracting quality tests
- Standard number of pump strokes - the number of pump strokes required to collect the standard volume of sample air for this tube
- Distinct layer of color change
- Reliable detecting reagents that comply with the Gastec's stringent quality standards
- Chemical formula of the substance to be measured, an abbreviation is used for a long formula
- Detector tube number - The numeral represents the kind of substance the tube can measure and the letter specifies the level of concentration the tube can determine, for example respectively indicate high, medium and low level concentration
- On-site measurements can be performed easily by anybody, anytime and anywhere, in a short time
- Easy-to-check direct reading possible due to the calibrated scale directly printed on the tube
- An extensive measuring range can be obtained by adjusting the sampling volume
- Long shelf-life with excellent long-term stability
- In order to assure high precision, each production lot is tested and calibrated independently, Each detector tube has its own quality control number printed on the tube
- Operating conditions : Temperature 0 to 40 deg C (32 to 104 deg ) correction not used, Relative humidity 0 to 90 % correction not used
- Relative standard deviation : 5 % (for 25 to 250 ppm)
- Shelf life - 36 months
- Detecting limit : 2.5 ppm (2 pump strokes)
