Contact OdorTest

OdorTest is a small, independent, ad-supported site — there is no support desk standing by, but a real person reads what comes in to support@odortest.com.

This address is genuinely useful for a few things: a calculator that gave a result you think is wrong (say which tool — the odor concentration calculator, dilution ratio calculator, odor emission rate calculator, detection threshold calculator, ventilation dilution calculator, or odor impact distance estimator— and the figures you entered); an olfactometry or odour-monitoring tool you wish existed here; an out-of-date fact or broken link in the blog, learn section, or the museum; or a bug in how a page looks or behaves on your device.

There is no fixed response time to promise, and no ticket number or live chat — email is read and handled as it comes in. If your question is really about a specific site, permit, complaint, or compliance decision, an accredited odour-testing laboratory or a qualified environmental practitioner will give you a far more authoritative answer than this site can. OdorTest’s calculators produce screening estimates, not certified measurements, and the site is not affiliated with any laboratory, standards body, or regulator.

Before writing in about a result, it is worth double-checking the values you entered — flows in mismatched units, a dilution factor, or a concentration are the usual source of a surprising answer. If it still looks off after that, that is exactly the kind of message worth sending.
