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 checked against a primary standard only once per month (or every 200 hours for coal mine dust sampling).

Features:

• 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.
• Inlet filter traps moisture and particular matter.
• Stainless steel-filled plastic case provides EMI/RFI protection.
• Rated IP66 for resistance to water and dust ingress.
• Exceptionally quiet operation.
• Flow-Fault Indicator shows any sample inlet blockage.
• Run/Hold feature allows “time out” during sampling process.
• Elapsed time readout and low-battery warning.
• Low flow and dual tube sampling available with Gemini Twin-Port Sampler.
• 2 Year Warranty.
