Escort ELF Pump with Gemini Sampler; 120 VAC

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|Collect two samples at the same time Valve allows flow control down to 0.001 L/min|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.|Draw samples at independent flow rates through tubes containing different sorbents when sampling for two or more contaminants. Connect two same type tubes simultaneously at different flow rates when sampling for a single contaminant. Included tube covers fit both large and small tube sizes.
