Air Flow Measurement

Customers tell us that this is the best pressure switch made. The Mercoid D Series is one of the worlds broadest lines of pressure switches. Whatever your application might be, it is most probable it can be fully satisfied with a D Series pressure switch. The D Series has extremely high sensitivity and great repeatability. The DA Models are equipped with two external adjustments, one for setting high pressure operating point, the other for setting low pressure operating point. Deadband, the difference between high and low set points, is adjustable over the full scale. The DS Models are equipped with a single external adjustment for setting operating point only. The deadband is fixed at a factory setting and cannot be altered in the field. For switches choose between the snap action switch, hermetically sealed snap action switch and hermetically sealed mercury switch. Visible calibrated dial On/off indication (except hermetically sealed snap switch models) Adjustable or fixed deadband SPDT snap-action, hermetically sealed snap action or hermetically sealed mercury switch External switch setpoint adjustments Minimum deadband is obtainable at any point in the range Pressure Ranges of full vacuum to 8000 psig UL listed, CSA approved. Many models FM approved General purpose, weatherproof or explosion-proof enclosures Snap Switch, Hermetically Sealed Brass Standard with Bottom Connection 9-64, SPDT 5 100 psig

The SERIES SAH SMART Air Hood is a revolutionary air flow hood, made with rugged polymer construction that represents the smallest and most aerodynamic design in the industry. The patent pending Quad Flow Design Technology is based on controlling air flow and minimizing back pressure which yields superior measurement accuracy. Featuring Wi-Fi direct communication, with a range of 200 yards between the hood and a handheld test instrument, the user interface, mobility, data storage and transmission has never been better. The SMART Air Hood includes Predictive Balancing, an industry first for air flow balancing. Predictive Balancing is a method of projecting the optimal flow set point for each diffuser while balancing the HVAC system. The handheld software application includes algorithms enabling Predictive Balancing to achieve best in class accuracy. Balancing can be done with just one technician. Patent pending Quad Flow Design Technology directs the circulating air patterns to provide a more even air flow that minimizes backpressure, enabling accurate readings. Predictive Balancing is a process that guides the balancing technician on setting the optimal flow set point for each sequential terminal. With the PredictAir™ Application Software, the balancing process takes much less time thatn traditional air balancing methods. The ergonomic design is much lighter and easier to work with than the existing bulky air hoods, providing greater maneuverability and less physical strain. One technician can complete the air balancing. Wi-Fi direct wireless communication provides a range up to 200 yards (183 m) > Each Unit Includes SMART Air Hood™ Balancing Instrument handheld test instrument extendable pole 4.5 to 12 extendable pole 2 to 4 pole safety clamp stationary pole adapter cable adapter charger and cables for SAH and handheld travel case

Wireless anemometer, hygrometer, and pressure probes communicate to the handheld using Bluetooth SIG, Inc. wireless technology and can all be displayed simultaneously. Each UHH2 includes a UHH2 handheld base unit, UHH-BTG wireless mobile gateway, two USB charging cables, charging block, mini-screwdriver, user manual, and headphones. Rugged weatherproof housing withstands 1.5 meter drop test Wireless measurement of pressure, air velocity, air flow, temperature, and humidity Share logged data directly from handheld over Wi-Fi, GSM, or CDMA networks > Each Unit Includes UHH-BTG wireless mobile gateway two USB charging cables charging block mini-screwdriver headphones
