Brand: FORENSICS DETECTORSModel: FD-4A-FLUEUser Manual: Click Here Blog Article: Click Here Features: ⚛️ RESIDENTIAL: Perfect for residential combustion and ambient air quality analysis or probe / continuous sampling in confined or toxic spaces. Comes FACTORY-CALIBRATED. 🌇 ACCESSORIES: Comes with a quality water trap, particle filter, and NOx filter to reduce cross-sensitivity errors. 🔬 SENSORS: High-quality electrochemical sensors with oxygen (O2) and carbon monoxide (CO). Calculates CO air free (COAF) and excess air (EA) for combustion analysis. Comes factory-calibrated. Detection error better than ≤±5% F.S. and response time: < 60 sec. 💪 STRONG: Robust design constructed with ABS and anti-slip grip rubber. Comes with a strong magnet for appliance mounting. Water-resistant, dust-proof, and explosion-proof. 🕵️ TRUSTWORTHY: 1-year limited warranty. Arrives with a signed and dated calibration certificate. Details: A basic and affordable residential combustion analyzer + handheld pump with high-quality O2 and CO sensors and large LCD with backlight. We developed this unit for HVAC professionals, contractors, or maintenance engineers for residential boilers, heaters, and furnaces. The display screen shows CO, O2, COAF (CO air-free), and EA (excess air %). The detector can be used as an ambient detector for general air quality measurements. When plugged into the pump, the analyzer can also function as a spot detector or combustion and flue gas analyzer. Please note, that this analyzer does NOT detect flue temperature nor calculate combustion efficiency. We also offer our more professional combustion analyzer which is an all-inclusive unit with a built-in pump and pistol probe. Please note, that this analyzer does NOT detect flue temperature or calculate combustion efficiency and does not detect nor calculate carbon dioxide (CO2). In addition, also note that this unit is not made for automotive exhaust gases since the CO in automotive combustion engines typically exceeds 1000 ppm CO and may blow out the CO sensor. For automotive exhaust applications, please see the auto exhaust gas analyzer. Included: The product comes with an aluminum hard case, analyzer containing CO and O2 sensors, strong niobium magnets for mounting on appliances while testing, an electronic pump with the stainless probe, hose assembly, 3 feet of high temp silicone tubing, water trap, particle filters, NOx filters with sensor cap, screw to mount sensor cap to the analyzer, USB charging cable, USB charger, certified calibration certificate, and user manual.
