Overview
The Zefon® Escort ELF® air sampling pump features 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).
