Frequently Asked Questions
Roll selection, lead-acetate sensing, compatibility, storage, and lifecycle questions.
What is H₂S sensing tape?
H₂S sensing tape is a treated analytical substrate used in tape-based hydrogen sulfide analyzers. Lead-acetate chemistry reacts with hydrogen sulfide to form a brown-to-dark lead-sulfide stain that the analyzer measures optically.
What is the difference between 100 ft and 330 ft H₂S sensing tape?
The sensing chemistry is controlled for the same analytical purpose, while roll length and analyzer fit differ. Blue Dragon uses the 100 ft BD-H2ST-100 with the 810H2S-P and the 330 ft BD-H2ST-330 with the 810H2S and 810H2S-TS.
Which H₂S sensing tape is used with Blue Dragon analyzers?
Use BD-H2ST-100 for the Model 810H2S-P. Use BD-H2ST-330 for the Model 810H2S and Model 810H2S-TS.
Are Blue Dragon H₂S sensing tapes compatible with other analyzer brands?
Selected Blue Dragon sensing-tape formats are cross-referenced for compatible applications from Galvanic, Envent, Thermo, Tracor, Houston Atlas and, for the 100 ft format, DelMar. Confirm the analyzer model, existing tape reference and reel configuration before ordering.
What is the shelf life of Blue Dragon H₂S sensing tape?
The minimum shelf life is 10 years when the tape is retained in its original protective packaging and stored in a cool, dry environment.
How should unopened H₂S sensing tape be stored?
Store the sensing tape in its original protective packaging in a cool, dry environment until it is required for analyzer service.
How should H₂S sensing tape be handled and disposed of?
H₂S sensing tape contains lead acetate. Wear protective gloves when handling the tape, prevent the material from entering drains or the environment, and dispose of tape waste in accordance with applicable regulations. Refer to the current Safety Data Sheet for complete safety information.
How do I select the correct sensing tape for my analyzer?
Start with the analyzer manufacturer, model, current tape part number and roll length. For Blue Dragon analyzers, use the controlled 100 ft or 330 ft mapping shown on this page. For third-party systems, confirm the cross-reference and reel configuration before ordering.
