What is the purpose of the Kanomax Tracer Gas DIF-Kit?

Our Tracer Gas Diffuser Kit, or Dif-Kit for short, is for use in performing the tracer gas test in accordance with ANSI/ASHRAE Standard 110-2016. The diffuser is made to the design and specifications of ASHRAE Standard Drawing #110-83M. Its purpose is to check fume hood performance to ensure that the hood is performing safely and to specifications.

There are a lot of options offered with the Dif-Kit. What should I order?

Kanomax offers a complete fume hood testing solution. However, because not everyone needs to perform every aspect of the ASHRAE test we sell the kit as 5 separate modules so customers only need to buy the pieces required for their application. Please consult our sales specialists for the appropriate choice for your needs.

Face Velocity Test

Anemomaster Professional: Our handheld anemometer is useful for performing a face velocity test at different points along the hood.

Visualization Test

Fog Machine: This unit is used to perform a visualization test. Visible smoke is released inside the fume hood and monitored to see if any visible amount is escaping. It can also be used to show how the air is flowing inside the fume hood so trouble spots where airflow is insufficient can be detected.

Tracer Gas Test

Diffuser-kit: The core part of the DIF-KIT includes a flow meter, regulator and diffusion ejector. This portion of the kit is used to release the tracer gas inside the fume hood. Manikin-kit: This portion includes a test mannequin (to simulate a person standing at the fume hood), lab coat and mannequin stand.

Vapor Analyzer or Leakage detector: Instrument is calibrated to detect the tracer gas, such as SF6 (sulfur hexafluoride), and can be useful in determining exactly how much, if any, of the gas is escaping from the fume hood.

Does the DIF-KIT come with a calibration certificate?

The flow meters that are part of the kit are also calibrated for use with the tracer gas.
