Portable Digital Gas Flow Meter - Thermal Mass Flow Tester for Air, Oxygen, Nitrogen, CO2, 0-20L/min, RS485 Modbus, Battery Powered (MF5706 (0-20L/min)
Precision Multi-Gas Measurement: Accurately test flow rates for air, oxygen, nitrogen, CO2, and inert gases (0-20L/min) with advanced MEMS thermal sensor technology. Achieve ±1% accuracy without temperature/pressure compensation—ideal for oxygen tester applications, compressed air audits, or medical gas validation. Features 80:1 turndown ratio and micro-flow sensitivity.
Industrial-Grade Portability & Power: Deploy anywhere with ultra-low power consumption—weeks of runtime via rechargeable battery or continuous AC adapter (110-240V). The compact handheld design includes a 180° rotatable display and G/NPT threaded connections for confined-space installations in HVAC, breweries, or labs.
Smart Alarms & RS485 Modbus Connectivity: Program custom flow range alerts via keypad for safety compliance, triggering visual alarms during over-limit conditions. RS485 Modbus enables networked monitoring, data logging, and integration with PLCs/SCADA systems—critical for pharmaceutical batch processes or emission testing.
Zero Pressure Loss & Robust Safety: Engineered with isolated anti-interference electronics, metal-shielded interfaces, and laser-etched wiring diagrams. Laminar flow path ensures near-zero pressure drop—perfect for peak flow meter testing in compressed air systems or oxygen concentrators without disrupting operations.
Cross-Industry Versatility: Serve diverse sectors: verify CO2 carbonation in beverages, test nitrogen purge rates in pharma, monitor agricultural greenhouse gases, or validate medical oxygen flow. Functions include emergency shutoff, external signal control, and on-site calibration for specialty gases.
