GASTEC Ammonia (NH3) Detector Tubes – Multiple Measurement Ranges

GASTEC Ammonia (NH3) Detector Tubes

GASTEC Ammonia Detector Tubes provide a convenient, direct-reading method for measuring ammonia (NH3) concentrations in air and gas samples. Designed for use with a compatible GASTEC gas sampling pump, these colorimetric detector tubes allow professionals to perform rapid on-site ammonia measurements without requiring an electronic sensor or laboratory analysis.

With available measurement ranges extending from 0.5–78 ppm to 1.2–19.2% ammonia, GASTEC offers multiple NH3 detector tube options for applications ranging from lower-level workplace and environmental monitoring to high-concentration industrial and process measurements.

Choose the Ammonia Detector Tube for Your Application

GASTEC offers multiple Ammonia Detector Tubes for measuring NH3 across a broad range of concentrations. Select the appropriate GASTEC product number based on the expected ammonia concentration and the requirements of your sampling application.

GASTEC Product Number	Ammonia Measurement Range
3H	1.2–19.2%
3HM	0.05–3.52%
3M	10–1,000 ppm
3LA	2.5–200 ppm
3L	0.5–78 ppm

 

Direct-Reading Colorimetric Ammonia Measurement

GASTEC detector tubes use a chemical reagent that reacts with the target gas as a measured volume of sample is drawn through the tube. The resulting color-change layer provides a visual indication of ammonia concentration that can be read using the calibrated scale on the tube and the instructions provided for the selected GASTEC product number.

This direct-reading measurement method provides a practical solution for industrial hygiene surveys, workplace air monitoring, process checks, leak investigations, environmental testing, and other applications where ammonia concentrations need to be evaluated directly at the sampling location.

Multiple NH3 Ranges for Low and High Concentrations

The available GASTEC Ammonia Tubes allow users to select a measurement range suited to the anticipated NH3 concentration. For lower-concentration measurements, the GASTEC 3L (0.5–78 ppm) and 3LA (2.5–200 ppm) provide ppm-level measurement capabilities.

The GASTEC 3M (10–1,000 ppm) extends measurement into higher ppm concentrations, while the 3HM (0.05–3.52%) and 3H (1.2–19.2%) are designed for substantially higher percentage-level ammonia concentrations. This broad selection allows users to choose a tube that more closely matches the expected conditions of the sampling environment.
