Important Points When Using the Gastec Hydrogen Sulfide Detector Tube 4LK

The Gastec Hydrogen Sulfide Detector Tube Model 4LK is a precise and efficient tool for measuring H₂S gas concentration in various industrial, laboratory, and environmental settings. This sampling system uses specialized Gastec pumps and tubes sensitive to hydrogen sulfide gas, providing fast and safe detection of this toxic gas. Given its wide application in the oil and gas, petrochemical, mining, steel, paper manufacturing industries, and air quality control, this detector plays an important role in maintaining workplace safety and employee health and is recognized as a reliable tool under diverse temperature and humidity conditions.

Preparation of the Sampling Pump

Use only Gastec sampling pumps (models GV-100 or GV-110) with Gastec tubes. Using non-Gastec parts or pumps may damage the system and pose serious risks. Before use, test the pump for leaks.

Breaking the Tube End

Break the tube end using the pump’s special tool.
Avoid contact with eyes and wear appropriate gloves while breaking.

Inserting the Tube into the Pump
Carefully insert the tube into the pump inlet, ensuring the arrow on the tube points toward the pump.
Make sure the pump handle is fully pressed in.

Sampling
Pull the pump handle fully out to lock it (for sampling 100 milliliters).
After one minute, confirm that sampling is complete.
For concentrations below 2 ppm, repeat the above steps once more.
For concentrations above 20 ppm, use a new tube and perform a half stroke (50 milliliters).

Reading the Results
Read the gas concentration at the point where the color has changed.
If necessary, adjust the results using correction factors related to the number of pump strokes and atmospheric pressure.

Operating Conditions
Suitable temperature range: 0 to 40 degrees Celsius.
Suitable relative humidity: 0 to 90 percent.
This tube may be affected by interfering gases.

Storage and Disposal
Store tubes in a cool, dark place.
Dispose of them according to local regulations.
