The New Cosmos Model XP-3340Ⅱ ATEX Portable High-Concentration Gas Detector (Order Code: Y5340-100E0-400D70, Target Gas: CO2, Measurement Span: 0 - 100% Vol), engineered and manufactured by New Cosmos Electric Co., Ltd. in Osaka, Japan, is a high-precision handheld instrument designed specifically for volumetric gas analysis during inert gas blanketing, tank purging, and industrial process monitoring.

Next-Generation Evolution of the Benchmark XP-3140:
Building upon the field-proven durability of the legacy XP-3140 series, the 2nd generation XP-3340Ⅱ incorporates significant mechanical and electronic advancements:
- Enhanced Structural Durability: Encased in an impact-absorbing elastomer boot engineered to survive drops from 1 meter onto solid concrete surfaces.
- IP67 Submersible Enclosure: Upgraded ingress protection protects internal electronics against driving tropical downpours and temporary liquid immersion.
- Integrated Bluetooth Wireless Telemetry: Seamlessly pairs with dedicated smartphone/tablet applications to transmit real-time gas concentration data, generate instant field safety logs, and trigger automated emergency email alerts to control supervisors.

Model Code Breakdown & Configuration (Y5340-100E0-400D70 / XP-3340Ⅱ ATEX):
- XP-3340Ⅱ: Second-generation portable suction-type high-concentration gas detector series.
- Target Gas CO2 (0 - 100% Vol): Microprocessor algorithms and sensor bridges factory-calibrated for Carbon Dioxide (CO2) from 0.0 to 100.0% volume.
- ATEX: Certified intrinsically safe conforming to European Union ATEX Directive Ex II 1G Ex ia IIC T4 Ga, rated for unrestricted deployment inside Zone 0 hazardous explosive atmospheres.
- Y5340-100E0-400D70: Complete factory delivery package including instrument body, flexible sampling probe wand, gas sampling hose with moisture filter trap, shoulder strap, and AA alkaline batteries.

Key Engineering Features & Operational Advantages:
- Robust Thermal Conductivity Sensing Principle: Operates via a precision Wheatstone thermal bridge measuring the thermal dissipation difference between the sampled process gas and reference air. Unlike optical or electrochemical sensors, thermal conductivity sensors will not saturate or degrade when continuously exposed to 100% pure gas concentrations, ensuring decades of stable service life.
- Integrated High-Flow Motorized Sampling Pump: Features an internal motorized diaphragm suction pump pulling ≥ 400 mL/min through a semi-rigid probe. Enables safety inspectors to draw gas samples safely from deep cargo holds, chemical reactor vessels, and inaccessible piping ducts prior to entry.
- Dual Numeric & Visual Bar-Graph LCD Display: Simultaneously presents high-resolution numeric concentration values down to 0.1% Vol alongside an intuitive visual bar graph. Features an integrated automatic backlight for dark equipment vaults.
- Multi-Tier Acoustic & Visual Alarm Architecture: Activates intermittent piezoelectric audio alarms (> 85 dB at 30 cm) and bright red flashing LEDs upon reaching pre-set concentration thresholds, flow obstruction (Flow abnormal), or low battery states.
- Data Logging & Modern Smartphone Integration: Logs historical gas values, alarm timestamps, and calibration events, easily downloadable via Bluetooth for electronic safety audits and compliance records.

Target Industrial Sectors & Applications:
- Marine & Maritime Cargo Operations: Inert gas purging verification (CO2 / N2) inside crude oil cargo tanks, chemical tankers, and LNG/LPG carrier insulation spaces prior to dry-dock inspections.
- Brewing & Carbonated Beverage Production: Monitoring CO2 accumulation across fermentation cellars, maturation tanks, bottling halls, and bulk CO2 gas recovery plants.
- Chemical, Petrochemical & Gas Processing: Quality monitoring in ammonia/urea synthesis towers, dry ice production plants, and high-pressure cylinder filling manifolds.
- Fire Protection & Suppression Systems: Safety testing and concentration decay verification for total-flooding CO2 fire suppression systems in server rooms, marine engine rooms, and electrical substations.
- Agriculture & Controlled Atmosphere Storage (CA): Monitoring optimal CO2 balance in commercial post-harvest fruit/vegetable cold storage vaults and high-yield greenhouses.
