UHH2 pole attachment7. Pole pins (Pack of 3)8. Charging cable and block for SMART Air Hood™9. Charging cable and block for UHH210. 1' x 4' hood with assembly packThe Series SAH SMART Air Hood™ is designed to measure air flow from HVAC air ducts and diffusers for balancing. The SAH is lightweight, rugged, and ergonomically designed for easy use and maneuverability. The interface is Wi-Fi direct to the UHH2 handheld and can transmit up to 200 yards (183 m). The unit includes an on/off switch and LEDs to alert when the unit is connected, transmitting, and when the battery is running low in order to avoid recording inaccurate measurements. The SAH SMART Air Hood™ is durable and easily stores in the included travel case.INTRODUCTION Do not use the UHH2/hood unit for liquid or gas mixtures other than air. No responsibility will be taken by Dwyer Instruments, Inc. for any resulting damage to the unit or to the operators if it is used with corrosive or dangerous or explosive gas mixtures. When using the UHH2/hood to check air flow at ceiling diffusers, make certain that you can raise and hold the unit safely during use. This instrument is not classified as flameproof or intrinsically safe; therefore, it must not be used where an explosion hazard may exist. The unit is not authorized for use on life support applications.Note: Observe standard safety procedures when working on ladders and scaffolding. Also, ensure the unit does not become caught in moving machinery or on sharp objects.• If stored under conditions outside normal operating range, allow the unit to stabilize at room conditions before use.• Owing to its size and shape, take care when carrying the assembled unit from place to place.• Avoid people and nearby equipment.• Avoid objects that may damage the capture hood.• Turn the instrument off before storage or transportation and remove the batteries if storing for long periods of time.• Avoid subjecting the capture hood sensing grid to excessive loading during use or assembly. Any air flow other than through the calibrated sensing holes, such as any hair-line cracks, will seriously affect the sensitivity.• A damaged sensing grid must be replaced. It cannot be repaired.• Take care when fitting different sized canvas hoods of the protruding pins at the capture hood.• Do not disassemble the sensing grid from the capture hood. The retaining structure is specifically designed to accommodate loading due to normal operation.• Under low humidity conditions, static electric charges may be encountered. These can be avoided by applying a suitable anti-static solution.Bulletin TE-SAHSeries SAH SMART Air Hood™SPECIFICATIONSVOLUME FLOWService: Air.Units: CFM, l/s, m3/h.Range: 30 to 2000 CFM.Accuracy for Any Diffuser > 50 CFM: ±3% of reading ±10 CFM.Resolution: 1 CFMTEMPERATUREUnits: °F, °C, K.Range: 40 to 140°F (4.4 to 60°C).Accuracy: ±1.8°F (±1°C).Resolution: 0.01°CRELATIVE HUMIDITYRange: 5 to 95%, non-condensing.Accuracy: ±5% of reading (no calibration required)Resolution: 0.04% RH.ABSOLUTE PRESSUREUnits: mbar, Pa.Range: 10 to 2000 mbar.Accuracy @ 25°C: ±2% of reading (between 300 and 1100 mbar).Resolution: 0.016 mbarPower Requirements: 3.7 V MH12210 lithium ion battery, included, user replaceable or (4) 1.5 V AA alkaline batteries, not included, user replaceable.Dimensions: 15" x 24" x 24" (381 mm x 610 mm x 610 mm).Weight: 5.5 lb (2.5 kg)Agency Approvals: CE, FCC.
