Product Description
This Nitrogen Oxides detection tube is designed for fast, reliable workplace air monitoring across a broad 5 to 625 ppm range. Built for efficient field use, the tube delivers clear colorimetric results in approximately 30 seconds to 1.5 minutes when used with a compatible detection tube pump.
Ideal for combustion systems, engine testing, boiler rooms, welding environments, and industrial hygiene programs, this tube supports dependable screening of NOₓ concentrations during routine inspections and process evaluations. The wide measuring range allows both low-level verification and higher concentration assessment within a single tube.
With a 2-year shelf life, this detection tube is well suited for routine inspections, exposure audits, and regulatory compliance monitoring where reliable nitrogen oxides measurement is required.
Typical applications include:
-
Combustion and exhaust gas monitoring
-
Engine and boiler system inspections
-
Welding and metal processing environments
-
Industrial hygiene exposure monitoring
-
Process safety verification
