Toxic Gas Detector System and Airflow Testing Kit

Complete line of detector tubes.

Toxic Gas Detector System

• Complete, easy-to-use sampling and analysis system
• Detects and measures hazardous gases and vapors
• Ideal for monitoring performance of Exhaust Purification Filters
• The most cost-effective solution to air sampling and analysis

This low-cost, portable system consists of two components: detector tubes detect specific vapors; and a precision sampling pump draws an air sample through the detector tube. One sample is all that is needed for most analysis, compared to other devices that require that you keep track of multiple strokes and introduce the possibility of operator error.

More than 200 detector tubes are available to measure a wide variety of hazardous gases and vapors. Each is formulated with high purity reagents that absorb and react with the gas or vapor being measured. The reaction causes a colorimetric stain which corresponds in length to the concentration of the gas or vapor being measured.

Air Flow Testing Kit

• Determines flow and strength of air currents
• Provides an inexpensive way to monitor the proper flow of vapors under the Exhaust Fume Hoods

The Air Flow Testing kit allows you to check the strength and flow patterns of slow-moving air currents. The kit is ideal for monitoring the correct operation of ventilators, air conditioners, and laminar flow stations; it also ensures that hazardous vapors under the fume hoods are properly vented. And because it helps determine the distribution of toxic vapors in the workplace, it allows you to determine the optimal measuring points for conducting air analysis with Terra's Gas Detector Kit (see above for a full description).

The Air Flow Testing kit consists of a hand-held rubber aspirator bulb, four rubber plugs, and ten air current tubes. A plastic case contains all components and includes a device for opening the air current tubes. Each of the 4³/4" (1448 mm)-long tubes contains a porous element impregnated with fuming sulfuric acid that produces the smoke. To release smoke, you simply break off the tips of a tube, insert one end into the bulb, and squeeze. Each tube contains two domed metal screens that hold the chemical reagent securely in place without hampering the free flow of smoke.

After use, simply remove the tube from the bulb and plug both ends with a rubber stopper. Tubes can be reused until the smoke is exhausted. Kit dimensions: 5.75" x 2" x 2.5" (146 mm x 57 mm x 64 mm). Kit Weight: 6 oz.
