Profile: Shortridge Instruments, Inc. is a manufacturer of AirData Multimeter™, and HydroData Multimeter™. Our product line includes AirData Multimeter™ multimeters, HydroData Multimeter™, FlowHoods and Velgrids. Our ADM series AirData Multimeters are used as hand-held portable meters for air velocity, pressure, and temperature measurement. These meters may also be used to obtain direct air flow readings with an 8400 FlowHood kit. Our ADM-880C AirData Multimeter™ stores 2000 readings, along with the time and date, in 25 memory groups. Each reading may be recalled along with the average, sum, minimum, maximum, and standard deviations of the readings for each mode within each group. Our FlowHood CFM-88L uses the electronic, digital AirData Flowmeter for direct readout at supply, return, or exhaust outlets, in cfm or liters/sec. This rugged, shock resistant meter automatically selects the proper range, and corrects for local barometric pressure and temperature. These features eliminate several error factors, and the calculations necessary to convert airflow readings to local density results. Internal calibration and zeroing are fully automatic.
