MTL Multi-Component Gas Analyzer
The MTL Multi-Component Gas Analyzer Series is a versatile gas analysis solution designed to meet a wide range of industrial measurement requirements. It supports applications such as environmental monitoring, energy and process operations, quality control, and continuous emissions monitoring. The analyzer can be configured with up to four detector modules within a single enclosure, allowing flexible sensor combinations and measurement ranges to suit different operational needs.
The analyzer is available in both 19-inch panel-mounted and wall-mounted configurations, providing installation flexibility for control rooms and space-constrained environments.
To ensure reliable and accurate measurements, the system can be integrated with the MTL Sample Gas Sampling System, which prepares extracted gas samples by stabilizing pressure, temperature, and moisture before analysis. This integrated approach enhances measurement accuracy, system reliability, and long-term performance.

MTL Explosion-proof Gas Analyzer
The MTL Explosion-Proof Gas Analyzer is designed for safe, reliable, and precise measurement of flammable gases in hazardous environments. It meets Japanese explosion-proof standards (JPEx) and is ideal for operations where safety and accuracy are critical.
The analyzer supports multiple gas types: infrared measurement for CO, CO2, CH4, and other organic gases; thermal conductivity for H2; and integrated magneto-pneumatic or paramagnetic detection for O2. Each configuration delivers consistent performance in industrial settings where explosive atmospheres may be present.
Certified for Hazardous Areas
Approved for operation in flammable and explosive environments in Japan, meeting JPEx explosion-proof standards.Self-Diagnosis Function
An automatic self-diagnosis is triggered whenever an abnormal condition is detected. The system also logs calibration factors and can manage auto-calibration for consistent performance.Reliable Gas Analysis
Correction or compensating detectors minimize interference from other gases, ensuring accurate measurement of the target gas.LED Display
The high-visibility LED display clearly shows the analyzer’s status, making monitoring straightforward for operators.
