Ammonia Detection Tubes 0.5/% (0.05 - 10 Vol.%)
Drager Short-term Tubes have proven to be a very cost-effective and reliable method for the measurement of gases.
For short-term measurements more than 160 Drager-Tubes are available to measure the so-called spot concentrations of specific gases. Measurement usually takes between 4 seconds and 15 minutes. The tubes are used either manually with the Drager-Tube pump accuro or automatically with the Drager X-act 5000.
A wide range of different gases and vapours can be detected and measured, e.g.: Determining and measuring concentration peaks, Measuring personal exposure in the inhalation area, Detecting leaks in pipelines, gas installations etc., and Air analysis in sewers, shafts and confined spaces.
|Standard Measuring Range:
||0.5 to 10 Col.-%
|Number of Strokes (n):
||1 + 1 desorption stroke in clean air
|Time for Measurement:
||20 sec. per stroke
||±10 to 15 %
||yellow ─> violet
||10 to 30° C
||3 to 12 mg H2O / L
||NH3 + pH Indicator ─> violet reaction
||This tube indicates other basic gases
e.g. organic amines
|Extension of the Measuring Range:
||Using n=10, divide the reading by 10; the range of measurements is 0.05 to 1 Vol.-%
