Our Services
During the warranty period, we provide free repair or replacement services for failures caused by manufacturing defects (excluding damage caused by misuse or external factors). After the warranty period, we will continue to provide maintenance services at transparent cost—charging only for parts and labor, with the specific price to be negotiated in advance based on actual needs.
Advantages of Online Gas Analyzer
Real-time fault detection: Provides continuous surveillance to catch abnormal gas formations or impurities in near-real-time, allowing operators to make immediate operational adjustments.
Predictive maintenance: Generates granular trend data that helps predict asset failures before they occur, shifting maintenance from reactive repairs to planned, proactive strategies.
Cost reduction: Minimizes production downtime, cuts labor costs associated with manual sampling, and extends the lifespan of critical equipment.
Enhanced safety: Eliminates the need for manual sampling, reducing human intervention and exposure to toxic, combustible, or asphyxiating environments.
Increased operational efficiency: Eliminates delays caused by laboratory wait-times, allowing for precise control of reaction mixtures to maximize yield and product quality.

Features of Online Gas Analyzer
High-accuracy multi-gas monitoring: Measures critical gases with ≤ ±3% full-scale accuracy, t90 response ≤ 30 seconds, and low zero drift (≤ ±1% fs/year). Ideal for early leak detection and personnel protection.
Field-replaceable sensor modules: Hot-swappable sensors are factory pre-calibrated for rapid deployment. While replacement is quick, zero/span verification is recommended after installation to ensure compliance with safety standards.
Non-contact maintenance via IR remote: Configure alarms, run diagnostics, or perform calibration without opening the enclosure-eliminating hot work permits and reducing exposure risk in hazardous zones.
Housing: Die-cast aluminum, corrosion-resistant finish.
Power: Wide-range dc 12–30 v, compatible with most industrial supplies.
Display
Color lcd for real-time status, alarm history, and diagnostics
Standard outputs
3-wire 4–20 ma + two spdt relays (for local alarms or shutdowns).
Optional
Rs-485 (modbus rtu) for digital communication.
Alarm
Optional integrated audible/visual beacon for on-site warning.
