Carbon disulfide gas sensor MST-N7M CS2

infraredNDIRmonitoring

Overview
MST-N7M is a nondispersive infrared (NDIR) gas sensor specifically designed to detect CS2 (carbon disulfide). Intended for industrial and environmental use, it supports continuous online monitoring and rapid leak detection with stable, long-term operation and a compact form factor.

Key features

• Environmental monitoring
• Gas leakage detection
• Online continuous monitoring
• Fast response and accurate measurement
• Resistant to poisoning
• Operates without requirement for oxygen
• Long lifespan (>5 years)
• Compact size
