Brand: FORENSICS DETECTORSModel: FD-4A-PUMPUser Manual Detector: Click HereUser Manual Pump: Click HereQuick Start Guide: Click HereBlog Article: Click Here Features: ⚛️ POINT SAMPLING: Perfect for point probe and continuous sampling in confined or toxic spaces. The pump flow rate is 0.5 LPM with easy USB recharge. Comes FACTORY-CALIBRATED. 🌇 DETECTION: High-quality sensors allow the 4 gas monitor to detect oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S), and combustibles (LEL). Comes factory-calibrated. Detection error better than ≤±5% F.S. and response time: < 30 sec. Zero and span calibration options. 🎆 ALARMS: Adjustable audio, visual, and vibration alarms alert when preset levels are reached. 💪 STRONG: Robust design constructed with high-strength ABS and anti-slip grip rubber. Waterproof, dust-proof, and explosion-proof. 🕵️ TRUSTWORTHY: 1-year limited warranty. Arrives with a signed and dated calibration certificate. Details: A basic multigas detector + PUMP setup by FORENSICS for easy use in industrial applications. The pump allows for a point probe or continuous sampling to avoid toxic environments. Simple LCD screen, large and with backlight. This instrument is used for confined space situations where a gas sample needs to be taken before entry to check the air quality, toxicity, and health of a confined space. The 4-gas meter and pump setup is a cost-effective alternative to other units that are more expensive with built-in pumps. For those requiring a 4-gas meter with a built-in pump, we recommend our FD-600-4GAS multigas detector. For those that just require a 4-gas meter for personal protection (without the pump probe), we recommend our 4-gas meter FD-4A. If data logging is required our FD-4S multigas detector is an excellent option. Includes: 4-gas Meter, user manual, computer USB charging cable, calibration cover, and certified calibration certificate. The pump unit comes with the pump, stainless probe, 3 ft silicone tubing, USB charging cable, and user manual.
