Kitagawa Toxic Gas Detector System

The Matheson-Kitagawa Toxic Gas Detector System is an ideal, easy-to-use method for day to day checking, screening, QC in the lab, plant or office, and spot testing for a wide variety of hazardous gases and vapors. It has been well-proven through extensive use by leading industrial companies and government agencies. This low cost, portable system is essentially comprised of two components: detector tubes, formulated to detect specific gases and vapors, and a sampling pump for drawing an air sample through the detector tube. See Kitagawa Tubes

 

The Model 8014KA is one of the most dependable, precise volumetric sampling pumps used with detector tubes. Its piston-type design reproducibly draws 100cc of sample air, and makes sampling easy and accurate. Unlike other pump designs, only a single stroke is needed for most analyses; there is no need for multiple volumes and stroke counters. The precision sampling pump requires only periodic routine maintenance, and carries a full five-year warranty. See Kitagawa Sampling Pump

 

There are now more than 250 detector tubes available to measure for a wide variety of hazardous gases and vapors. Each is formulated with a specific high purity reagent that absorbs and reacts with the gas or vapor being measured, causing a colorimetric stain. Four types of tubes provide the needed flexibility for different gases and sampling conditions. See Kitagawa Tubes

 

1.     Direct Reading Scale –

In this type, the colorimetric stain varies in length proportionally to the amount of gas or vapor being measured. The concentration is read directly off a scale etched on each tube. Most of the Matheson-Kitagawa tubes are of this type, and are signified by either the letter “S” or “U” appearing in the detector tube model number.

 

2.     Chart Comparison Tubes –

This type works similarly to the direct reading type. After a sample is taken, 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 utilize 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.
