Leaders in Personal Exposure Monitoring

Assay Technology is the global leader in air samplers for personal exposure monitoring. We also provide AIHA-LAP accredited industrial hygiene lab services. Our samplers are the most convenient & cost-effective way to monitor for chemical exposures, including: organic vapors, aldehydes, amines, nitrous oxide, anesthetic gases, ethylene oxide, hydrogen peroxide, and more. We also manufacture the Miller Nelson atmosphere generator, HCS-501, for control of flow rate, temperature and humidity, and we provide chemical capacity testing of respirator cartridges and media.

DOD Technologies is a leading manufacturer/distributor of low-level gas detection systems and solutions. Our industrial-grade gas detection systems are utilized to detect toxic and corrosive gases – at their lowest levels – commonly found in semiconductor plants, foam manufacturing facilities, oil and petrochemical plants, specialty chemical facilities, emergency response areas, wastewater facilities, laboratories, commercial buildings, and more. With a portfolio that includes colorimetric, electrochemical, catalytic bead, FTIR, and PID technologies, we provide fixed and portable systems that can detect a wide array of gas hazards. Manufactured to the highest standards, these systems help ensure employee safety while reducing or eliminating operational downtime. In addition to our manufactured solutions, we partner with other top tiered global manufacturers to bring you more quality gas detection products.

DOD Technologies also offers comprehensive services to ensure your gas detection systems continue to function optimally. We have skilled technicians on hand for expert repair (mail-in or on-site), calibration, and training services. Check out our technical services page to learn more, as well as our gas detector equipment trade-in and loaner programs.

When safety and reliability is a must, trust DOD Technologies… The Leader in Low-Level Gas Detection.

We are Ideagen Reactec, helping forward-thinking organizations move from mitigating industrial health risks to preventing them. This is what we call prevention engineering, powered by a connected ecosystem of workplace wearables and cloud-based analytics. With comprehensive risk exposure data, organizations can refine methods, apply effective controls, and actively protect worker health.
The R-Link Watch captures workers’ exposure to noise, dust, proximity hazards, and hand-arm vibration. It integrates with external sensors, provides real-time alerts to workers to guide correct behavior, and gives supervisors instant access to team risk profiles and insights to identify and manage high-risk jobs or workers.
Paired with the Reactec Analytics Platform, the R-Link Watch delivers clear visibility of exposures, audit-ready records, and actionable insights to identify risks, implement controls, and maintain compliance.
Our expanding digital ecosystem includes integrations with leading partners such as Casella, Cirrus and Larson Davis for noise monitoring, and Trolex for dust monitoring. By combining wearable and sensor-based technology, organizations can capture workplace risk exposure, address potential health impacts, and protect their workforce.
Why does it matter? When an incident or claim occurs, enforcement agencies aren’t interested in sporadic surveys or how much you spent on PPE. They care whether you assessed risks properly, identified high-risk areas, and applied the hierarchy of controls effectively.
We provide non-disruptive, regular risk assessment, helping you identify and manage workplace risks effectively. With centralized control and documentation, you have a single platform to record control measures, track interventions, and maintain audit-ready compliance records. Automated data capture ensures that, at the end of each shift, exposure data syncs to the Reactec Cloud, allowing you to analyze by group, date, or individual worker and access trend insights over time to refine controls and demonstrate compliance.
Ideagen Reactec transforms exposure data into actionable insights for prevention, compliance, and healthier workplaces.
