Introduction to Portable Methane Detection Alarms:
Portable methane detection alarms serve as essential tools for methane safety monitoring in high-risk environments. In scenarios such as oil extraction, gas distribution, underground coal mining, and municipal pipeline maintenance, As a highly flammable and explosive gas, methane (CH ) leaks can trigger catastrophic explosions and fires. The portable methane detector, distinguished by its portability, real-time monitoring capability, and high sensitivity, serves as the core equipment for preventing methane-related safety risks.
Portable methane detectors are used for rapid on-site methane concentration detection, temperature/humidity measurement, and alarm activation upon exceeding thresholds. The MS400 composite four-in-one gas detector features a 2.31-inch high-definition color screen for real-time concentration display. It employs gas sensors from renowned brands, utilizing detection principles including electrochemical, infrared, catalytic combustion, thermal conductivity, and PID photoionization. Featuring advanced circuit design and mature core algorithm processing, it holds multiple software copyright patents and design patents. The MS400 detects gas concentrations in pipelines, confined spaces, or atmospheric environments, identifies gas leaks, and measures high-purity single-gas concentrations against nitrogen or oxygen backgrounds. It detects over 500 gas types.
Portable Methane Detector Alarm Features:
Splash-proof, dust-proof, explosion-proof, shock-resistant; intrinsically safe circuit design; anti-static and anti-EMC interference; certified by national standards testing and CMC measuring instrument production license
IP65 protection rating; built-in moisture and dust filters prevent sensor/instrument damage from humidity and particulates
Built-in pump-assisted measurement with integrated moisture and dust filters. Optional professional accessories for high-temperature, high-humidity, and high-dust environments. Rapid response; specialized circuit design enables sampling distances exceeding 10 meters.
2.31-inch high-definition color display shows real-time concentration, alarms, time, temperature, humidity, storage, communication, battery level, and charging status. Menu interface uses high-definition simulated icons to display function names.
Large-capacity data storage: Standard 100,000-data-point capacity, with customizable higher capacities. Supports real-time storage, scheduled storage, or alarm-triggered data logging with timestamps. Data can be viewed/deleted locally or uploaded via USB to a computer for analysis, storage, and printing using host software.
USB charging port compatible with computers or power banks, also compatible with mobile phone chargers. Features overcharge, over-discharge, overvoltage, short-circuit, and overheat protection. 5-level battery level display. Supports USB hot-swapping; the detector operates normally while charging. Optional RS485 communication.
Equipped with a 4600mAh high-capacity rechargeable polymer battery for extended continuous operation.
Multi-sensory alarms: audible/visual/vibration alerts, low-voltage warning, and fault indication. Comprehensive alarm status display during alerts.
Configurable alarm thresholds with selectable modes: low alarm, high alarm, range alarm, weighted average alarm
High-precision temperature/humidity measurement (optional), with sensor temperature compensation. Operating range: -40°C to 70°C. Detects gases up to 400°C; higher-temperature detection available via customization (optional high-temperature sampling cooling filter handle or high-temperature/humidity pre-treatment system)
Optional simultaneous detection of 1–4 gases. Units freely switchable. Standard gases require no molecular weight input; special gases automatically calculate and switch upon molecular weight input. Selectable units: PPM, mg/m³, Vol%, LEL%, PPHM, ppb, mg/L.
Three display modes: Simultaneous display of four gas concentrations, large-font cyclic display of single-channel gas concentration, real-time curve. Automatic or manual cycling between channels. Configurable display of maximum/minimum values, gas names, and historical curve charts.
Selectable Chinese/English interface (default Chinese). Concise Chinese or English operation prompts.
Data recovery function: Selective or full recovery options eliminate concerns over accidental data loss.
Automatic zero tracking ensures long-term stability unaffected by zero drift.
Three-point target calibration guarantees measurement linearity and accuracy compliant with both national standards and local metrology bureau requirements.
Automatic detection and prevention of incorrect concentration calibration operations to avoid human-induced errors.
Supports real-time or scheduled detection (for low gas concentrations), with pump shutdown during non-detection periods to extend operational lifespan.
Records calibration logs, maintenance logs, and troubleshooting measures; includes sensor lifespan alerts and next calibration schedule reminders.
