Velocity Grid for Clean Room Testing
Product Announcement from Shortridge Instruments, Inc.
The VelGrid comes complete with:
- Pushbutton Handle
- Extension Rods
- Tubing Harness
- Meter Neck Strap
The VelGrid is an accessory especially designed for use in the measurement of general face velocity conditions.
Applications include exhaust hoods, HEPA clean room filter outlets, laminar flow work stations, and large filters and coils.
The VelGrid is a 12" square, 16 point, face velocity grid for coil, filter, fume hood and clean room testing. Each reading represents the input of 16 velocity points over a one-square foot area.
A 54-inch adjustable extension handle, and meter neckstrap allow convenient positioning and use of the VelGrid.
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. One to two week turnaround on calibrations
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.
MODELS - ADM SERIES Multimeters
The Model ADM-880C AirData Multimeter stores 2000 readings, along with the time and date, in up to 25 memory groups.
The Model ADM-870C AirData Multimeter provides maximum capability for the most demanding air balance requirements.
The Model ADM-850L is a simplified version of the AirData Multimeter.
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 displaying 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.
