Backup power and emissions testing

Large data center campuses can have dozens or even hundreds of backup generators and on-site turbines, and many must be permitted, commissioned and emissions tested before the site goes live. Source testers measure pollutants such as NOx, CO, VOCs, particulate matter, formaldehyde and ammonia slip from SCR systems. We supply the fittings, quick connects, valves and PTFE tubing those test crews use on their sampling systems. See our stack testing supplies page.
