Staplex FR-2 flow recorder

Staplex Flow Recorder Type FR-1 and FR-2 For High Volume Air Sampler HVAS TSP, PM10 and PM2.5 Provides a continuous written record of high volume air sampler flow rates • Accurate to ± 2% full scale • Includes 60 charts and pen • Made in U.S.A. Specifications: Model FR-1 115 VAC, 60 Hz Model FR-2 230 VAC, 50Hz Size: 5-1/4 #34; x 5-1/4 #34; x 4 #34; (13.3 cm x 13.3 cm x 10.2 cm) Weight: 2.5-lbs. (1.1 Kg) Accessories: FRC100 Circular Charts (100/box) FRP6 Cartridge Pen (6/pack Description : Staplex Model FR-1 and FR-2 Flow Recorders provide a permanent written record of High Volume Air Sampler performance to verify sampler flow rate over a 24-hour period. Models FR-1 and FR-2 connect to an exhaust pressure tap of a High Volume Air Sampler, such as Staplex Model TFIA and TFIA -2. The air sampler flow rate is recorded on a circular chart that is electrically driven by the recorder. The flow recorder connects to the power source for chart rotation over the sampling time. The recorder #39;s pressure measuring elements are heat-treated to prevent hysteresis-related inaccuracies. Models FR-1 and FR-2 are accurate to + 2% full scale. Each circular chart is calibrated in cubic feet per minute (CFM) and cubic meters per minute (CMM), with 24-hour chart movement gradations. Staplex Models FR-1 and FR-2 feature metal case, which mounts to the inside the Staplex SAM Aluminum Outdoor Shelter or similar shelter. Models FR-1 and FR-2 meet the requirements of a continuous flow recorder as stated in 40 CFR Part 50, Appendix B Reference Method for sampling Total Suspended Particulates (TSP) in the atmosphere and 40 CFR Part 52, No. 120 Appendix J for PM10 Air Sampling. Each unit includes 100 charts, pen, tubing to connect to High Volume Air Sampler and plug-in Made in U.S.A.
