Features:

  • ⚛️ SENSOR: High-quality sensors are included in this 4 gas monitor to detect Oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S), and combustibles (LEL). Comes FACTORY-CALIBRATED.
  • 🌇 DETECTION: Detection error better than ≤±5% F.S. and response time: T < 30 sec. Zero and span calibration options.
  • 🎆 ALARMS: Adjustable audio, visual, and vibration alarms when preset levels are reached. 
  • 💪 STRONG: Robust design constructed with high-strength ABS and anti-slip grip rubber. Water-resistant, dust-proof, and explosion-proof exceeding Exib IIB T3 Gb.
  • 🕵️ TRUSTWORTHY: ** 1-year limited warranty ** Arrives with calibration and QA certificates ** Product tested and verified in the USA ** 

Details: This is our most popular 4-gas personal monitor. This is a multigas detector with functions and incorporated high-quality sensors having a large LCD and with backlight. This 4 gas monitor is robust for industrial use by utility workers, refinery workers, firefighters, maintenance engineers, and those who spend time in sewers and waterworks, underground storage tanks, oil rigs, tanks, and silos in the maritime industry. 4 gas monitors are essential dangerous environments and confined spaces and for those that need personal protective equipment to monitor their breathable atmosphere is healthy and safe. For those requiring a 4-gas meter with a built-in pump, we recommend our FD-600-4GAS multigas detector. If an external pump is required, we offer this unit with a multigas detector pump combo. The ultimate 4 gas monitor is our 4 gas data logger, and for stationary continuous monitoring, we have our 4 gas wall mount monitor.

Included: Multi-gas detector, English manual, computer USB charging cable, charger, calibration cover, metal belt clip, nut to secure cap, and NIST calibration and QA certificates.
