Sensors](https://www.setra.com/product/environmental-monitoring) # Environmental Monitoring Package It is crucial to maintain the environmental conditions in spaces like hospital rooms, cleanrooms, data centers, and other critical spaces. Setra Systems has developed a reliable and accurate environmental monitoring package to suit any critical space. Anchored by our Setra FLEX Environmental Monitor, you can connect any of our sensors (including temperature, humidity, pressure, velocity, particle counters) or most third party sensors to build the environmental monitoring package that best suits your needs. [![setra-flex-room-environmental-pressure-monitor](https://www.setra.com/hs-fs/hubfs/setra-flex-room-environmental-pressure-monitor.png?width=250&name=setra-flex-room-environmental-pressure-monitor.png)](https://www.setra.com/setra-flex) # Setra FLEX™ Environmental Monitor & Controller At the heart of our environmental monitoring solution is Setra FLEX. Setra FLEX is designed to monitor differential pressure right out of the box. However, its much more than just a room pressure monitor. Setra FLEX will be truly appreciated when connected with our other sensors including additional pressure sensors, temp/humidity sensors, particle sensors, and more. Setra FLEX also ties back to your BMS so you can monitor critical spaces from anywhere. [**Learn More About Setra FLEX**](https://www.setra.com/setra-flex) Setra FLEX is the hub of your environmental monitoring package. Choose from our high accuracy sensors below to complete your package. All the sensors below work directly with Setra FLEX. Setra FLEX also works with most third-party sensors. # Setra Lite™ Visual Pressure Indicator [![setra-lite-room-pressure-indicator](https://www.setra.com/hs-fs/hubfs/setra-lite-room-pressure-indicator.jpg?width=250&name=setra-lite-room-pressure-indicator.jpg)](https://www.setra.com/product/environmental-monitoring/setra-lite) **NEW!** View room pressure status at a glance with Setra Lite.
