Marathon is a renowned manufacturer of process analytical instruments, offering their MMI series (Marathon Monitor Instruments).The nitos International hydrogen analyzer is widely used in the field of industrial gas detection, particularly in dissolved gas analysis (DGA) of transformer oil in power transformers, hydrogen production processes, and chemical processes. Below is a summary of key information about the MMI original imported probe-type hydrogen analyzer:

1. Product Features

High-Precision Detection: Utilizes thermal conductivity (TCD) or electrochemical principles to detect concentrations as low as ppm levels.

Original probe design: Direct insertion installation, suitable for real-time monitoring inside pipes or containers, reducing sampling delay.

Withstanding harsh environments: probe materials are typically made of stainless steel or special alloys, resistant to high temperatures, high pressure, and corrosive gases.

Quick Response: Optimized airflow design with short response time (typically <30 seconds).

Automatic Calibration: Some models support automatic calibration, reducing maintenance needs.

2. Typical Application Scenarios

Power Industry: Dissolved Gas Monitoring in Transformer Oil (predictive maintenance for transformer faults).

Chemical/Hydrogen Production: Purification processes, ammonia synthesis, fuel cell technology, etc. process controls.

Laboratory: High purity or mixed gas analysis.

Safety Monitoring: Leak Detection (e.g., nuclear power plants, petrochemical factories).

3. Technical Specifications (e.g., for common models)

Measurement Range: 0 to 1000 ppm to 0 to 100% H2O (varies by model).

Accuracy: ±1% FS (Full Scale).

Output Signal: 4-20 mA, RS485/Modbus, or Ethernet communication.

Protection Rating: IP65/IP67 (Dust and Water Resistant).

Certification: ATEX, UL, CE, etc. (for explosion-proof areas).

4. Advantages and Comparison with Competitors

Advantages:

Original import quality, high stability, and long lifespan.

Engineered for industrial environments, with strong anti-interference capabilities.

Marathon brand offers global technical support and services.

6. Maintenance Recommendations

Regular calibration (recommended every 6-12 months).

Avoid contact of the probe with oils or particles to prevent contamination.

Check the airway for sealing integrity, ensuring that the sampled gas has no condensation water.
