Brand: FORENSICS DETECTORSModel: FD-4SUser Manual: Click HereBlog Article: Click Here Features: 🌈 COLOR: Color screen and graph functions allow for easy and intuitive operation. Comes FACTORY-CALIBRATED. 🔬 ACCURATE: High-quality sensors for detecting oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S), and combustibles (LEL). Comes factory-calibrated. 📲 PRO: USB recharging and comes FACTORY-CALIBRATED. 💪 STRONG: Robust design constructed with high-strength ABS and anti-slip grip rubber. Waterproof, dust-proof, and explosion-proof exceeding Exib IIB T3 Gb. 🕵️ TRUSTWORTHY: 1-year limited warranty. Arrives with a signed and dated calibration certificate. Details: A professional multigas analyzer with advanced specifications, features, and premium electrochemical gas sensors. This detector features an advanced 32-bit microprocessor with color LCD and graphing capabilities. Made for industrial use by utility workers, refinery workers, firefighters, maintenance engineers, and those who spend time in sewers, waterworks, underground storage tanks, oil rigs, tanks, and silos in the maritime industry. We also have many researchers and scientists purchasing this unit for research purposes. Many others who need personal protective equipment can use multigas detectors to know that the atmosphere is healthy. A data logging version of a 4-gas monitor is also available. For those requiring a 4-gas meter with a built-in pump, we recommend our FD-600-4GAS multigas detector. We also recommend our multi-gas NIST traceable calibration gas and calibration gas bottle regulator. For bump testing, we recommend our multi-gas bump gas. For those that just require a more basic 4-gas meter without the advanced multigas detector function, we recommend our 4-gas meter FD-4A. If an external pump is required, we offer this unit with a multigas detector pump combo. Included: Multi-gas detector, user manual, USB recharging cable, calibration cover, nut to secure, and certified calibration certificate.
