ST450EC DETECTION OF TOXIC GASES AND OXIGEN

The ST450EC is an all-round gas detector which functions well under the most difficult circumstances. The heart of the detector is a replaceable gas sensor, which is available for Oxygen, Toxic gases and Hydrogen. The measuring principle is based on an electrochemical sensor, which is developed to meet the highest standards. The sensor has an outstanding stability, which achieves long-term reliability. The high selectivity of the sensors minimalizes “false” readings. The ST450EC comes standard with a graphic display. The 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.

Key feature:-

Detection of toxic gases, Oxygen and Hydrogen
ATEX / IECEx approved
Zone 1/21 without barrier
Sensor hot swappable in Ex Zone
Touch screen control, without additional tools
Reliable sensor technology

Application Note

ST450EC Detection of Toxic Gases and Oxygen is a high-performance fixed gas detector designed for continuous monitoring in industrial and hazardous environments. Engineered to detect toxic gases along with oxygen and hydrogen, it provides accurate and reliable measurement for safety-critical applications.

The detector is based on advanced electrochemical sensor technology, delivering high sensitivity, stability and excellent selectivity. This ensures precise gas detection while minimizing false readings, making it highly dependable in complex industrial conditions.

At its core, the ST450EC features a replaceable sensor design that enhances operational life and reduces maintenance costs. The integrated graphical display provides real-time gas concentration readings along with system status updates, enabling efficient monitoring and control.

User interaction is simplified through capacitive touch controls, allowing easy navigation of configuration and calibration menus without requiring additional tools. Designed for hazardous environments, the detector is ATEX and IECEx approved and supports operation in Zone 1 and Zone 21 areas without the need for external barriers.

A key advantage is its hot-swappable sensor capability, allowing safe and quick sensor replacement directly within Ex zones, minimizing downtime and improving operational efficiency. Widely used in industries such as chemical processing, marine operations, water treatment, food production and medical facilities, the ST450EC ensures safety compliance, reliability and long-term performance.
