Containment test for fume cupboards

Applications

Fume cupboards in laboratories, secure weighing cabinets, walk-in fume hoods, during installation tests and routine service

Frequently asked questions

• What is the purpose of the newly developed SKAN conttest?

  The conttest determines the amount of a harmful substance that escapes when a unit is half-open. It determines the concentration of a substance in the air inside the fume cupboard as well as on the “body” and “arms” of an operator, directly at the work area. From the raw data, the containment performance is determined as a performance class from 0 to 3. This patented test provides a clear understanding of the current performance of fume cupboards and instils confidence in occupational safety.

• What makes conttest different from other test methods?

  The test system uses a more environmentally friendly solvent.

  It also employs a human-like dummy which tests the environment using standard robot movements, which simulate the movement typical of someone working in a fume cupboard. Measurements are then taken at nose, chest and abdomen height to determine if any substances are escaping from the fume cupboard. The test result is printed out on-site, ensuring operators are adequately protected during their routine work at the fume cupboard.

• Can the conttest be used to measure several multiple fume cupboards in one building?

  The SKAN conttest mobile measuring station is specifically designed for this purpose and delivers fast measuring times. At least 8 fume cupboards can be measured per test device per day using this method.

Environmentally friendly
Energy-saving

The break-out test for fume cupboards not only works with an environmentally friendly gas but also detects faulty installations. With the conttest, the energy consumption of fume cupboards can be reduced through better performance: excessively ventilated fume cupboards can be identified and valuable energy can be saved if they are rectified immediately. This affects approx. 3% of all measured fume cupboards.
