The LFS-113 Air Sampling Pump Features:Dual Mode Automatic Constant Flow or Constant Pressure Control Multi-flow Capacity Compact Size & Lightweight Flow Fault Indicator Light Clock Model with Elapsed Time Display Battery Check LED
The Gilian LFS-113 low flow sampler is the most powerful and reliable pocket sized personal air sampler available today. The LFS-113 offers two sampling modes selectable by the user. The constant flow control mode holds the flow within +/-5% of the set flow while the multi-flow (constant pressure control) mode allows multiple samples to be taken simultaneously. No other pocket-sized pump matches the wide flow range and high back-pressure capability of the LFS-113. Basic and clock models are available in both US and Global versions. Global versions are now available with a memory-free NiMH battery. Approvals
UL, CSA, C-US, ATEX PERFORMANCE | | Flow Range | 1- 350cc/min | Low Flow Range | Constant Flow: 20-200cc/min, to 25" H2O | Constant Pressure (Multi Flow): | 1-350cc/min, to 18" H2O | Constant Flow Control | Better than +/- 5% of set flow (after calibration) | Run Time | 8 hour minimum | Flow Fault | If flow changes exceed 5%, fault icon appears. If fault exceeds 30 seconds, pump shuts down. Clock [Timer] model will retain sample time during fault shutdown. | ENVIRONMENTAL | | Temperature Ranges | | Operating | -20°C to 45°C (-4°F to 113°F) | Storage | -40°C to 45°C (-40°F to 113°F) | Charging | -40°C to 45°C (-40°F to 113°F) | Humidity Ranges | | Operating | 0-85 %RH, non-condensing | Storage | 0-100 %RH, non-condensing | GENERAL | | Features | Dual filtration system, sorbent tube end breaker, belt clip | Controls | Power Switch, Flow Control Screw | Indicators | Flow Fault, Battery Check | Icons (LCD) | Elapsed Time (DC model only) | Dimensions | 6.35W x 11.76H x 3.51D cm
