Gastec Ammonia (NH₃) Gas Detector Tubes provide a convenient method for measuring ammonia gas concentrations in air using a compatible Gastec gas sampling pump.

Designed for on-site gas detection, industrial hygiene, workplace air monitoring, occupational safety, and environmental testing, Gastec detector tubes provide a simple visual method for measuring specific gas concentrations without requiring electronic gas detection equipment.

Multiple measuring ranges are available to accommodate low-level, standard, high-concentration, and percentage-level ammonia monitoring applications, allowing users to select the appropriate Gastec detector tube for their specific testing requirements.

Common Applications

Gastec Ammonia Gas Detector Tubes can be used with compatible Gastec sampling equipment for workplace air monitoring, industrial hygiene surveys, occupational exposure assessment, refrigeration systems, cold storage facilities, agriculture and livestock operations, fertilizer production and handling, chemical manufacturing and processing, water and wastewater treatment, laboratory environments, environmental monitoring, ammonia leak detection, process monitoring, and workplace safety applications where ammonia gas may be present.

Important

A compatible Gastec Gas Sampling Pump is required to use these detector tubes. Always select the appropriate detector tube and measuring range for your target gas and follow the manufacturer's sampling instructions and correction factors, when applicable, for the specific tube being used.
