Environmental Monitoring Systems

Cleanrooms & Controlled Environments Environmental sensors used in cleanrooms, hospitals and controlled environments are quite different to those that are commonly used in HVAC systems, BMS systems, buildings, offices, homes and other environments. Their measurement range, accuracy, suitability for cleanroom environments and other factors all come into play including their ability to be calibrated and re-calibrated in accordance with GMP and industry requirements. Temperature, humidity, differential pressure, particle counters, gas and other sensors are all commonly used in cleanrooms and controlled environments and selecting the right sensors can make a world of difference in accuracy and reliability. Temperature, humidity, CO2 and a wide variety of other environmental sensors are available for continuously monitoring cleanrooms, equipment, fridges, freezers, -80 deg freezers, incubators, nitrogen tanks, hot cells and many other controlled environments. Welding Fumes The Dangers of Ultrafine Particles Ultra-fine particles in the air pose a significant health risk to humans. This has been widely known by industry for many years and there are countless articles and pages sighting health effects on the internet to this effect. The World Health Organization (WHO) has even acknowledged this and has recommended monitoring ultrafine particles is crucial for comprehensive air quality assessment. The Pegasor Airin provides a reliable and effective way to detect and monitor these tiny particles in indoor and urban environments. Ultrafine particles are present in welding fumes, diesel particulates, smoke and many manufacturing processes indoors and outdoors. If you can’t measure them properly, then how can you expect to control them. Most optical particle counters and or dust monitoring instruments on the market focus on measuring larger sized particles and can only measure particles down to 500nm, 300nm or 100nm in size at best. They are typically designed for monitoring cleanrooms or PM dust fractions indoors / outdoors such as PM1, PM2.5, PM10 and or larger and are not optimized for ultrafine particle measurements. There are however many industries and organizations interested in measuring and controlling ultra-fine particles in an effort to protect their staff or the general public however the technology to measure ultrafine particles has traditionally been expensive to purchase and maintain.
