Escort ELF Air Sampling Pumps: Advanced Flow Control and Reliability

Escort ELF air sampling pumps are equipped with cutting-edge electronic laminar flow sensors, ensuring consistent flow control with ± 2.5% regulation for flow rates between 1-3 LPM. The pumps automatically adjust for variations in battery voltage, temperature, altitude, and sample load. An internal secondary standard continuously calibrates the pump, requiring only monthly checks against a primary standard (or every 200 hours for coal mine dust sampling).

Key Features:

• Patented Electronic Laminar Flow Control: Maintains precise flow rates for reliable sampling.
• Continuous Internal Calibration: Ensures OSHA compliance with minimal maintenance.
• Infrequent Primary Standard Checks: Required only once a month or every 200 hours for coal mine dust applications.
• Inlet Filter: Captures moisture and particulate matter for cleaner samples.
• Durable Construction: Stainless steel-filled plastic case provides protection against EMI/RFI.
• IP65 Rating: Offers resistance to water and dust ingress.
• Quiet Operation: Designed for minimal noise during use.
• Flow-Fault Indicator: Alerts users to any blockages at the sample inlet.
• Run/Hold Feature: Allows for a pause in the sampling process when needed.
• Elapsed Time Readout and Low-Battery Warning: Keeps you informed of sampling progress and battery status.
• Versatile Sampling Options: Low flow and dual tube sampling available with the Gemini Twin-Port Sampler.
• 2-Year Warranty: Ensures long-term reliability and support.

Approvals:

• NIOSH Certified: For coal mine dust sampling (TC-74-030).
• MSHA Certified: As intrinsically safe for underground use (Approval # 2G-3924-1).
• UL Approved: As intrinsically safe for hazardous locations, including Class I (Groups A, B, C, D), Class II (Groups E, F, G), and Class III (Division I) environments.
