Zefon Elf Pump with Mining Cyclone & 120v Charger 

Available in 1 pack or 5 pack 

Escort ELF air sampling pumps feature a state of the art electronic laminar flow sensor to provide a constant flow control with ± 2.5% regulation of flow rate (from 1-3 lpm) with automatic compensation for changes in battery voltage, temperature, altitude, and sample load. An internal secondary standard calibrates the pump continuously and needs to be checked against a primary standard only once per month (or every 200 hours for coal mine dust sampling).

• Patented electronic laminar flow control.
• Internal secondary standard calibrates the pump continuously, maintaining OSHA compliance.
• Check against a primary standard only once a month or every 200 hours for coal mine dust sampling.
