GLS Detection Tube

Quick and accurate measurement of environmental gases anywhere

GLS Gas Detection Tubes detect trace environmental gases and provide measurements of gas concentrations within minutes from any site. A portable, handheld sampling pump conveniently delivers sample gas allowing GLS Gas Detection Tubes to be easily used wherever and whenever gas detection is required. A wide selection of tubes allows for the detection of up to 250 different target gases.

FEATURES

  • High accuracy (ppm and <1% scale) measurement of trace gas concentrations
  • Portable, compact pump system for handheld operation and carry
  • Direct reading of results straight from the detector tubes
  • Multiple gas concentrations ranges available
  • Wide selection of gas detection tubes for up to 250 different types of target gases

Overview

The GLS Gas Detection Tube System is comprised of GLS Detection Tubes and an Air Sampling Pump (AP-20). Each detector tube is formulated with high purity reagents that absorb and react with the target gas being measured. A colorimetric stain is created which is proportional in length to the target gas concentration. The concentration is read directly off the measurement scale on each tube for most applications. 

Using the AP-20 Air Sampling Pump (sold separately) sample gas is delivered to detector tubes in uniform increments of 50mL for a half-stroke and 100mL for a full stroke. All gas detector tubes are calibrated for use with n half or full strokes so that gas sampling is managed by stroke count.

GLS Detection Tube System Operation

Below is the basic operating flow of the GLS Detection Tube System:

1. Do preliminary pump check

Gas Aspirating Pump Step 1

2. Cut both ends of the gas detector tube

Gas Aspirating Pump Step 2

3. Connect the gas detector tube to the aspirating pump

Gas Aspirating Pump Step 3
 
 

4. Pull the handle

Gas Aspirating Pump Step 4

5. Draw the sample gas

Gas Aspirating Pump Step 5

6. Return the handle and read concentration off the gas concentration tube
