GX-3R

The GX-3R is the world's smallest and lightest 4-gas portable detector, designed to protect workers in hazardous environments by simultaneously monitoring four gases:

• Combustible gases (LEL)
• Oxygen (O₂)
• Hydrogen sulfide (H₂S)
• Carbon monoxide (CO)

Key Features

• Ultra-Compact Design: Weighing only about 3.52 ounces (100 grams) and measuring approximately 2.2 x 2.55 x 1.02 inches, it's designed for comfortable, continuous wear.
• Durability: The device is water and dust resistant with an IP66/68 rating, ensuring reliable performance in harsh conditions.
• Long Battery Life: Equipped with a rechargeable lithium-ion battery that provides up to 25 hours of continuous operation on a single charge.
• User-Friendly Interface:
  • Two-Button Operation: Simplifies use, reducing training time.
  • Clear Display: Bright, backlit LCD screen shows real-time gas concentrations and alarm conditions.
  • Alarms: Features audible (95 dB at 30 cm), visual (bright LED lights), and vibration alarms to immediately alert the user of hazardous conditions.
• Safety Features:
  • Man Down Alarm: Alerts others if the user becomes immobile.
  • Automatic Calibration Reminder: Ensures the device remains accurate over time.
  • Data Logging: Stores exposure data for record-keeping and analysis.
• Wireless Communication (Optional):
  • Bluetooth Connectivity: Allows for real-time monitoring and data transfer to compatible devices using dedicated software or apps.
• Accessory Compatibility:
  • Docking Stations: Compatible with SDM-3R calibration stations for automated bump testing and calibration.
  • Pump Adapter (Optional): Can be attached for remote sampling in confined spaces.

Technical Specifications

• Detection Ranges:
  • Combustible Gases (LEL): 0-100% Lower Explosive Limit
  • Oxygen (O₂): 0-40% Volume
  • Hydrogen Sulfide (H₂S): 0-100 ppm
  • Carbon Monoxide (CO): 0-500 ppm
• Sensor Types: High-quality micro-electrochemical sensors for toxic gases and oxygen; catalytic combustion sensor for combustible gases.
• Response Time: T90 (time to reach 90% of the final reading) is less than 30 seconds for most gases.
• Operating Conditions:
  • Temperature: -4°F to +122°F (-20°C to +50°C)
  • Humidity: 0 to 95% RH (non-condensing)
• Power Supply: Rechargeable lithium-ion battery with a charging time of approximately 3 hours.
• Certifications:
  • Safety Approvals: ATEX, IECEx, CSA, and UL certifications for use in hazardous locations.
