Electronic laminar flow sensor provides constant flow control with ±2.5% accuracy
- Internal secondary standard continuously calibrates the pump
- NIOSH certified for coal mine dust sampling
- MSHA certified as intrinsically safe for underground use
- UL approved as intrinsically safe for use in Class I, Groups A, B, C and D; Class II, Groups E, F and G; Class III, Division I locations
Maintain the flow you need with Escort ELF air sampling pumps. Pumps feature a state-of-the-art laminar flow sensor for constant flow control with automatic compensation for changes in battery voltage, temperature, altitude, and sample load. Check against a primary standard is needed only once a month (or every 200 hours for coal mine dust sampling) to ensure accuracy.
An IP65-rated, stainless steel filled plastic case provides EMI/RFI protection. An inlet filter protects the pump by trapping moisture and particulate matter. Run/hold feature allows "time out" during sampling process. Flow/fault indicator lights up when the inlet is blocked. Low-battery indicator lets you know when it is time to charge the NiMH battery.
