ST350EX-V/ST350EX-F DETECTION OF CX HY AND REFRIGERANTS

The ST350EX is an all-round gas detector and useful for many applications. The heart of the detector is a replaceable gas sensor. This sensor is available in various versions, such as a SCV and a SCF sensor. The SCV sensor is suitable for the detection of Aromatic Hydrocarbons at ppm level (for example Toluene or Xylene) and also for Carbon disulfide (CS₂). The SCF sensor is suitable for the detection of synthetic refrigerants (H)CFK’s and HFK’s. These are well known Freon’s such as R134a, R407c and the newer type R1234yf. Both the SCV and the SCF sensors are stable over their entire long life-time. A solid cost of ownership! The ST350EX is available with or without a graphic display. The version with a graphic display, shows the measured value and various status notifications locally. The capacitive key control gives you an experience similar to a touchscreen and enables easy navigation through the user/calibration menu. The user menu is secured with a password; unauthorized users cannot access the gas detector.

Application Note

ST350EX-V/ST350EX-F DETECTION OF CX HY AND REFRIGERANTS – ST350EX-V and ST350EX-F Detection of Aromatic Hydrocarbons and Refrigerants is a specialized gas detection solution designed for precise monitoring of hydrocarbon compounds and synthetic refrigerant gases in industrial environments. Engineered for high sensitivity applications, it enables accurate detection at ppm levels, making it ideal for leak detection and environmental monitoring.

The ST350EX utilizes advanced sensor technologies tailored to specific applications. The SCV sensor is optimized for detecting aromatic hydrocarbons such as toluene, xylene and carbon disulfide (CS₂), while the SCF sensor is designed for synthetic refrigerants including (H)CFKs and (H)FKs such as R134a, R407c and the newer R1234yf. These sensors offer excellent long-term stability and durability, ensuring consistent performance over extended operational periods.

Built with a replaceable sensor design, the detector minimizes maintenance efforts and reduces total cost of ownership. It is available with an optional graphical display that provides real-time gas concentration readings along with system status notifications, enhancing operational visibility.

User interaction is simplified through capacitive touch controls, enabling intuitive navigation of configuration and calibration menus without the need for additional tools. The system includes password-protected access for secure operation.

Widely used across industries such as chemical processing, refrigeration systems, marine operations and environmental monitoring, the ST350EX plays a critical role in detecting gas leaks, ensuring safety compliance and optimizing system performance in sensitive industrial applications.
