This Toxic Gas Detector System is an ideal, easy-to-use method for day-to-day gas checking. It allows effective monitoring of exhaust purification filter efficiency. It also provides a valuable aid to QC in the lab, plant or office and spot testing for a wide variety of hazardous gases and vapors.

This low-cost, portable system consists of two components: detector tubes detect specific vapors; and a precision sampling pump draws an air sample through the detector tube. One sample is all that is needed for most analyses, compared to other devices that require that you keep track of multiple strokes and introduce the possibility of operator error.

More than 200 detector tubes are available to measure a wide variety of hazardous gases and vapors. Each is formulated with high purity reagents that absorb and react with the gas or vapor being measured. The reaction causes a colorimetric stain which corresponds in length to the concentration of the gas or vapor being measured. Four types of tubes provide the needed flexibility for different gases and sampling conditions.

1. Direct Reading Scale.
In this type, the colorimetric stain varies in length proportional to the amount of gas or vapor being measured. The concentration is read directly off a scale etched on each tube.
2. Chart Comparison Tubes. This type works similar to the direct reading type above. A sample is taken and the stain length is compared to a printed concentration chart enclosed with each box of tubes.
3. Color Comparison Tubes. In this type, the intensity of color change, rather than the length of stain, is compared to a standard color chart.
4. Multi-Part Tube Sets. The multi-part tube sets use a pre-treat or primary reaction tube in addition to the detector tube. The “front-end” tube scrubs the sample air of either moisture or potentially interfering gases, which might otherwise cause erroneous results.

Operation is Simple
Only three easy steps are needed to operate the detector: first, you break off the tips of a fresh detector tube; second, you insert the tube, with arrow pointing toward the pump, into the pump’s inlet; third, you pull out the pump handle to automatically lock, and the pump begins to draw a 100cc sample through the detector tube. A proprietary Sample Vue indicator shows when sampling is completed. More detailed information is on an instruction card enclosed with each pump and box of detector tubes. The precision sampling pump is certified by the Safety Equipment Institute (SEI).

Detector Tube Ordering Information
See chart below
Notes (1) Tubes are packed ten per box unless otherwise indicated.
  (2) Measuring range is in parts per million unless otherwise indicated.
  (3) Each tube tests for both NO (10-300 ppm) and NO2 (1- 40 PPM). Cat. No. 9003-88 is for air sampling, 9003-89 is for hot flue gases (with pre-treat tubes to dehumidify). Each box has tubes for 5 tests.
