STRATUS GC-1 EX
The operating principle of the STRATUS GC-1 EX system is based on measuring the response time to molecules of various gases passing from the capillary column to the electrochemical sensor. The continuous monitoring mode is programmed as a schedule in the device's controller and can be customized to your needs at any time. This continuous monitoring is particularly crucial for VOC control in industrial and agricultural facilities, where air quality monitoring plays a vital role in ensuring the safety of workers and inhabited areas. The continuous mode enables more accurate tracking of hazardous substance levels in the surrounding environment and timely response to any changes related to industrial processes and agriculture.
The monitoring system has the capability to connect up to 16 channels through a router, which can be conveniently added as an additional option from ATHERO. This expanded connectivity allows for more comprehensive data exploration and analysis, providing a more detailed understanding of the air quality conditions in the surrounding space.
The STRATUS GC-1 EX device comes equipped with a modem for remote connectivity, ensuring it is always accessible online for the operator. This feature allows the operator to remotely access the device, retrieve data, and promptly respond to any changes detected by the sensor. The modem enables seamless communication between the monitoring system and the operator, ensuring continuous and real-time monitoring of gas levels and providing the ability to take immediate action when necessary. This remote access capability enhances the efficiency and effectiveness of the monitoring process, making the STRATUS GC-1 EX a reliable and user-friendly solution for gas detection and air quality monitoring.
