Gas Detectors & Gas Analysers

Portable and fixed gas detection, continuous emissions monitoring, and multi-gas analysis systems — engineered for safety, process control, and environmental compliance across industrial applications.

Comprehensive Gas Analysis for Safety & Compliance

Labtech Electronics offers a complete range of gas analysers and detection systems for industrial safety monitoring, continuous emissions monitoring (CEMS), process gas analysis, and environmental compliance. From single-gas personal detectors to multi-component stack emissions analysers, our instruments are designed for reliability in the most demanding environments.

Our gas analysers support a wide range of measurement technologies — electrochemical, catalytic bead, infrared (NDIR), photoionisation (PID), and paramagnetic — ensuring the right sensing principle for every application. All instruments offer 4–20mA, HART, Modbus, and relay outputs for seamless integration with plant control and safety systems.
