Nitrous oxide as a tracer gas

ASHRAE Standard 110, Section 4.1, outlines the use of sulfur hexafluoride, a potent greenhouse gas, for tracer gas testing. Alternatives to sulfur hexafluoride have long been sought due to its contribution to climate change. Technical Safety Services has pioneered the search for alternative tracer gasses. TSS has conducted extensive research into the use of nitrous oxide as an alternative tracer gas, resulting in a ~99% reduction in TSS' carbon footprint when performing fume hood tests. Our studies have convinced the University of California system, the United States Department of Energy and several other clients to adopt nitrous oxide as a valid alternative tracer gas. Further, TSS' work provides a roadmap for the qualification of other gasses.

Fume hood airflow alarms

In accord with regulatory bodies and in keeping with fundamental laboratory safety, TSS encourages the use of calibrated quantitative airflow monitors in conjunction with any operational fume hood. Quantitative airflow monitors are the best way to ensure your chemical fume hood is operating safely and in compliance with ASHRAE 110 and other regulatory parameters.

CONTACT TSS for more information regarding the benefits of a quantitative airflow monitor over other airflow indication devices.

To better suit your specific needs, TSS offers you a choice in airflow monitors:
