About OHD
In the past 30+ years, OHD has grown into a globally recognized leader in workplace safety, occupational health and industrial hygiene. Headquartered in Hoover, Alabama, we specialize in advanced instrumentation and software solutions designed to safeguard employee health and manage occupational risks.
Our flagship products, the QuantiFit2® and the AeroFit™, provide the best fit testing experiences on the market. As the world’s only manufacturer offering both OSHA and ISO-recognized quantitative fit testing technologies, we lead the industry in precision and reliability.
The QuantiFit2 utilizes patented controlled negative pressure (CNP) technology. It delivers accurate respirator fit tests in under two minutes, operable virtually anywhere without the need for consumables. Coming in late 2024, the AeroFit, utilizing condensation nuclei counting (CNC) technology, provides the best user experience for CNC fit testing.
OHD is also the U.S. Master Distributor for Gilian air sampling equipment and SVANTEK noise and vibration equipment. We also offer spirometers, audiometers, and other occupational health solutions.
