More About this Item

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.

Easily adjust flow rate using a button keypad. An IP65-rated, stainless steel filled plastic case provides EMI/RFI protection. An inlet filter protects the pump by trapping particulate matter; a water stop filter prevents moisture from entering the pump. 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.
