Gastec Nitrogen Oxides (NO + NO2) Detector Tube – No. 11L

Combined Analysis for Combustion and Emission Monitoring

The Gastec No. 11L detector tube is specifically engineered to measure the total concentration of Nitrogen Oxides (Nitric Oxide and Nitrogen Dioxide combined). Nitrogen oxides are common byproducts of high-temperature combustion and are strictly regulated for environmental and workplace safety. This tube provides a simple, direct-reading solution for assessing air quality and process efficiency without the need for complex electronic analyzers.

Key Features

• Dual Gas Detection: Simultaneously detects both Nitric Oxide (NO) and Nitrogen Dioxide (NO2) for a total NOx reading.

• Trace Level Accuracy: Capable of measuring low concentrations from 0.03 to 14 ppm, ensuring precise monitoring of ambient and process air.

• High Contrast Results: Features a clear colorimetric change (White \rightarrow Grayish Red) for easy visual confirmation of gas levels.

• Pre-Calibrated Scale: The direct-reading scale on the glass allows for immediate data collection in the field.

• Premium Manufacturing: Produced in Japan under rigorous quality standards (QC No. 50894) for reliable, repeatable performance.
