MBr Gas Detector Tubes

MBr Gas Detector Tubes

Gas Detector tubes, also known as colorimetric gas detection tubes, are sealed glass tubes filled with a sensing chemical. When air from inside or outside the fumigated space is drawn through the tube using the appropriate gas sampling pump, the sensing chemical inside changes color and forms a stain. The length of the stain thus formed is proportional to the gas concentration present at the point of sampling and can be easily read from the scale printed on the tube.  

Detector tubes enable the user to easily make spot measurements of Methyl Bromide in the fumigated area. MBr Tubes are available in the lower concentration levels of 1 ppm. 

We offer a choice of both thick and thin tubes (KwikDraw and Uniphos) within our portfolio. 

PH3 Dosimeter Tubes

PH3 Dosimeter Tubes

Uniphos Dosimeter tube is a device, very similar to gas detector tubes, that provides the Concentration-Time product (Dose) of phosphine during the entire fumigation durationBut, unlike normal detector tubes, phosphine enters the dosimeter tube by natural diffusion.

Detector tubes enable the user to easily make on the spot measurements of Phosphine in the fumigated area. PH3 Tubes are available both in the lower concentration levels of 0.01 ppm, as well as the fumigation concentration levels of 400 to 5000 ppm.

Phosphine Detector Strips

Phosphine Detector Strips

Phosphine detector strips alert workers of the presence of PH3 in dangerous levels.  The strips change colour from their original yellow to pink when exposed to PH3 gas. The time it takes to change colour can be related to the PH3 gas concentration in the environment.  They can be used to check the fumigated area for the presence of PH3 after aeration is complete and to confirm that the area is safe for re-entry. These strips can also be given to workers as badges when they are working in/near fumigated structures.  

Uniphos Tubes

Detector Tube Technology  The Uniphos brand of detector tubes are used with the precision ASP-40 piston hand pump. The air sample is drawn through the narrow tube containing a specific gas sensing chemical causing a color change.  The length of color stain gives the concentration which is read directly from the measurement scale printed on the tube. The piston style pump and tube configuration often have the measurement based on a single pump stroke.   Uniphos detector tubes provide a simple measurement of chemicals in gas samples. Since the tubes are pre-calibrated, no calibration is necessary and hence are absolutely free of maintenance.   More than 250 different Uniphos Gas Detection Tubes are available for over 150 different chemicals and concentration ranges
