Eranntex MS600-C2H6 Portable Ethane (C₂H₆) Gas Detector

Overview

The Eranntex MS600-C2H₆ is a certified intrinsically safe, portable ethane (C₂H₆) gas detector engineered for field-deployable, real-time monitoring in industrial and environmental applications where rapid, reliable quantification of ethane concentration is critical. Designed around catalytic combustion sensing technology—optimized for hydrocarbon detection in the lower explosive limit (LEL) range—the instrument delivers high reproducibility and long-term stability under variable ambient conditions. Its core architecture integrates a precision-matched pellistor sensor with temperature-compensated signal processing, enabling accurate measurement across a 0–100% LEL range (equivalent to 0–4.9% vol in air). The device complies with IEC 60079-0 and IEC 60079-11 for intrinsic safety, and meets China’s mandatory CMC certification requirements for metrological instruments (approval no. valid per national registry). It operates continuously in extreme environments—from arctic cold (−40°C) to desert heat (+70°C)—and maintains functional integrity during brief water immersion (IP67), making it suitable for pipeline integrity verification, landfill gas surveys, natural gas distribution leak audits, and fugitive emission screening per EPA Method 21 protocols.

Key Features

• Intrinsically safe design certified to Ex ia II CT4, compliant with GB 3836.1–2010 and GB 3836.4–2010 standards
• IP67-rated enclosure with replaceable hydrophobic particulate/moisture filter—enabling operation in high-humidity, high-dust, or rain-exposed scenarios without sensor degradation
• Built-in 500 mL/min sampling pump with extended reach (≥10 m via optional coiled tubing), supporting both diffusion and active draw sampling modes
• 2.5-inch 320×240 TFT color display with multi-mode UI: simultaneous 4-gas view, large-font single-channel mode, and real-time concentration trend curve
• Configurable alarm logic—including low/high/interval/weighted-average thresholds—with triple-alert output (audible ≥75 dB, dual-color LED, haptic vibration)
• On-device data management: 100,000-record non-volatile memory; SD card expansion; USB/RS232/Bluetooth/GPRS export options
• Intelligent power system: 6000 mAh Li-polymer battery with 5-level state-of-charge indication; hot-swap capable; supports operation while charging via USB-C or standard 5 V adapter
• Auto-zero tracking and multi-point span calibration support, with embedded calibration log storage and due-date reminders per ISO/IEC 17025 traceability guidelines

Sample Compatibility & Compliance

The MS600-C2H₆ is validated for direct measurement of ethane in ambient air, process streams, confined spaces, and soil gas matrices. It accommodates background gases including N₂, O₂, CO₂, and CH₄ without cross-interference when configured with catalytic combustion sensors calibrated specifically for C₂H₆. Optional infrared (IR) or photoionization (PID) modules extend capability to broader VOC profiling or inert gas purity verification (e.g., ethane-in-nitrogen analysis). All configurations adhere to national metrological verification regulations (JJG 693–2011 for flammable gas detectors) and support GLP-compliant documentation workflows. Device firmware and data logs meet audit-trail requirements aligned with FDA 21 CFR Part 11 principles when used in regulated environmental QA/QC programs.

Software & Data Management

The included PC-based upper-computer software (Windows/macOS compatible) enables full configuration, historical data visualization, statistical summary (min/max/avg/stdev), report generation (PDF/CSV), and compliance-ready export for regulatory submissions. Data files include timestamped metadata: sensor ID, calibration history, battery voltage, ambient T/RH (if equipped), pump status, and alarm event flags. Firmware updates are delivered via signed binary packages with SHA-256 hash verification. Optional cloud integration supports MQTT-based telemetry for centralized fleet monitoring across distributed sites—fully compatible with SCADA and CMMS platforms.

Applications

• Natural gas transmission & distribution: leak detection at compressor stations, metering skids, and valve pits
• Landfill and biogas facilities: quantifying C₂H₆ as a tracer for methane migration or anaerobic digestion efficiency
• Petrochemical refineries: monitoring ethane slip in ethylene cracker off-gas or flare stack emissions
• Environmental consulting: conducting EPA Method 21 surveys and preparing Tier 2/Tier 3 GHG inventories
• Emergency response: first-responder deployment for post-incident hydrocarbon vapor mapping
• Academic research: field studies on atmospheric hydrocarbon speciation and soil-gas exchange dynamics

FAQ

What detection principle is used for ethane in the standard MS600-C2H₆ configuration?
Catalytic combustion (pellistor) sensing—optimized for C₂H₆ within the 0–100% LEL range.
Can the instrument measure ethane in high-temperature exhaust streams?
Yes—when paired with the optional high-temperature sampling handle (rated to 1300°C) and integrated cooling/filtering module.
Is the device suitable for use in Class I, Division 1 hazardous locations?
Yes—its Ex ia II CT4 certification confirms suitability for Zone 0/1 (IEC) and Class I, Div 1 (NEC) environments.
Does the unit support regulatory audit trails for calibration and maintenance?
Yes—embedded logs record date/time, operator ID (optional), span gas concentration, zero offset, and pass/fail status per ISO/IEC 17025 Annex A.3.
How is sensor drift compensated during long-term field deployment?
Through automatic baseline correction (zero tracking) and scheduled multi-point calibration using certified reference gases traceable to NIST SRMs.
