HVAC Air Balance System
Featured Product from Shortridge Instruments, Inc.
The Airdata micromanometers are handheld portable multimeters for measuring velocity, pressure, and temperature of air at HVAC diffusers. They can also be used to obtain direct air flow readings with a FlowHood kit. AirData Multimeters are used by air balance experts in demanding air distribution applications for maintaining air quality control.
The 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. No adjustments are ever needed.

Shortridge Instruments, Inc. developed the analog FlowHood in 1974, and invented the line of unique electronic digital readout AirData Multimeters in 1984, providing direct readout of air flow, velocity, pressure and temperature. The rugged, reliable field instrument automatically zeroes and automatically corrects for the density effects of barometric pressure and temperature. Readings in English or metric units. All calibrations certified NIST traceable. Calibration program maintained in compliance with ANSI/NCSL Z540-1, ISO 17025 and MIL-STD 45662A.
AirData Multimeter for Every Application Shortridge Instruments, Inc., offers five different levels of AirData Multimeters. The entry level model CFM-88L reads air flow, temperature, and absolute pressure, and comes complete with an 8400 FlowHood kit. The more advanced meters may be used with a FlowHood, but also read velocity and differential pressures, including static and velocity pressures. The powerful model ADM-880C provides true datalogging functionality with a 2000 reading memory, recall of each time and date stamped reading, and the associated temperature and pressures recorded for each reading. The average, sum, minimum, maximum, and standard deviation may be viewed for each of the 25 user selectable memory groups. Readings may be downloaded directly to a computer or printer.
ADM Kits - Complete Solutions AirData Multimeter kits include industry standard pitot tubes, static pressure probes and tubing. The ADM-880C, 870C and 860C AirData Multimeters also include two proprietary probes which make air balancing faster and easier. The AirFoil probe is a single point velocity probe with a straight shaft design for easy duct insertion. The VelGrid is a 16 point, velocity averaging grid, which is useful for exhaust hoods, cleanroom filter outlets, laminar flow workstations and large filters and coils.
HDM Kits Provide Complete Solutions
The HDM-250 HydroData Multimeter is designed for efficient, accurate pressure and temperature measurements of nonpotable water. This meter functions as a compound pressure gage, simultaneously measuring the high side and low side pressures, along with the differential pressure, and displays each of the readings in sequence. Any mix of readings may be stored for later recall. The HDM-250 kit supplies key accessories for water pressure measurement, including a Valve Network Panel, hoses and a variety of brass fittings.
FlowHood Tops for Every Application
Standard FlowHood top sizes supplied with FlowHood kits are 2'x2', 2'x4', 1'x4', 3'x3' and 1'x5'. Two standard sizes may also be ordered for use with slotted diffusers, 5.25"x47" and 5.25"x60" and two standard sizes are offered for Direct Inflow Measurement (DIM) on cleanroom cabinets: 8"x24" and 10"x24". Custom top sizes available on request.
Shortridge Instruments, Inc. is proud to continue providing calibration and service support for ALL MODELS (previous and current) of the AirData Multimeter, HydroData Multimeter and FlowHood.
