Our pioneering products are designed to function in the harshest industrial occupational environments worldwide. From dust monitoring to gas detection and sensors, we’ve made it our mission to help you keep your workers safe.

With an estimated 1 million people dying globally from the inhalation of dust in occupational environments every year, now is the time to protect your workers. We’re continuously innovating our real-time dust monitoring technology to give you access to the information to effect change and keep your workers safe from hazardous respirable dusts.

Protecting workers for over 60 years, we have worked in a range of industries globally, with the aim of saving lives. Our safety technology is easy-to-use, easy-to-maintain and competitively priced, making the future of monitoring devices simple and effective for everyone.


Our ethos has been to create fixed and personal dust monitors that require virtually no maintenance and stay functional in even the most challenging of industrial environments. Our dust monitoring technology gives you simple, accurate data in real time so you can make decisions that save lives and improve efficiency.


There are 100 times as many deaths in the workplace caused by the inhalation of dust as there are from every other cause of death in the workplace combined. We simply can’t allow this to continue. We’re on a mission to help you change this through simple, accurate real-time dust monitoring in even the harshest of industrial environments.

Our dust monitoring technology has been in development for over 9 years. We’ve put in over 20,000 hours of testing in our purpose-built laser-lab to create a technology range that breaks traditional flaws of slow, expensive and complicated methodology. Being simple and effective helps you make important business decisions that make a real impact. Dust monitoring homepage > Real-time dust monitoring | Trolex

Pioneering technology made simple.

Air XS is the first and only product in the world to detect and distinguish respirable crystalline silica (RCS) in real time. Designed to function in challenging industrial environments, it detects all forms of crystalline silica and can track changing levels of RCS in complex dust mixtures over time.

The risk of occupational silicosis.

It is estimated between 40 to 50 million workers worldwide are exposed to harmful silica dust in the workplace. Our journey to develop the Air XS Silica Monitor comes from over 150 years of personal battles protecting workers from the dangers of silica dust and because of this we truly believe real-time RCS data is the key to ending the problem of silicosis in the workplace.

Protect your greatest asset. Your people.

The Air XS unit’s instant alarm allows for decisions to be made regarding intelligent use of PPE and RPE, agile process development and smart deployment of ventilation and extraction systems, overtime reducing costs, improving business efficiency, and ultimately save lives.

Data you can act upon.

Compatible with the Air XS, our Breathe XS software makes storing, accessing, and interrogating its data quick and simple. This clear, easy-to-use software allows you to configure your units remotely, in real time, all from a single dashboard.
