Product Description
This Sulfur Dioxide detection tube is designed for extended-duration air monitoring across a controlled 0.2 to 100 ppm range. Unlike short-term spot tubes, this model supports long-term sampling from 1 to 10 hours, making it ideal for time-weighted exposure assessment and trend evaluation.
Ideal for industrial hygiene programs, environmental monitoring, and regulatory compliance testing, this tube allows accurate measurement of average SO₂ concentrations over a full work period. The wide low-to-mid range provides both sensitivity and flexibility, supporting exposure verification in fluctuating operating environments.
With a stable 3-year shelf life, this detection tube is well suited for compliance monitoring, exposure audits, and documentation sampling where dependable long-term sulfur dioxide measurement is required.
Typical applications include:
-
Time-weighted exposure monitoring
-
Industrial hygiene compliance programs
-
Environmental air quality studies
-
Combustion and exhaust system evaluation
-
Regulatory documentation sampling
