Principles of Operation :
The state-of-the-art electronic laminar flow sensor, consisting
of a laminar flow element and pressure sensor, provides constant
flow (volume) control, with +/- 2.5% regulation of flow rate
(from 1 to 3 lpm) and automatic compensation for changes in
battery voltage, temperature, altitude and sample load.
Approvals & Standards :
Escort ELF Sampling Pumps are UL approved as intrinsically safe
for use in hazardous locations - Class I, Groups A, B, C, D;
Class II, Groups E, F, and G; and Class III, Division I
locations. NIOSH certified for coal mine dust sampling
(TC-74-030). MSHA certified as intrinsically safe for
underground use (Approval No. 2G-3924-1).
Applications :
Chemical
Construction
Mining
Oil and Gas
Sand Blasting
Sanding & Grinding
Spray Painting
Hazards :
Nuisance Odor
Particulate and Dust
Toxic Atmosphere Non-IDLH

Product Information :
The Escort ELF Sampling Pump can be used for personal and area
sampling. An internal secondary standard calibrates the pump
continuously and needs to be checked against a primary standard
only once a month (or every 200 hours for coal mine dust
sampling).
