AirData Multimeter
The ADM-870C from Shortridge Instruments is a versatile instrument used in Air Testing and Balancing that performs the following essential functions:
- This meter measures air velocity when used with a Pitot tube, AirFoil probe, or VelGrid and automatically corrects for density variations due to local temperature and barometric pressure.
Velocity ranges are 25-30,000 fpm using a pitot tube, 25-5,000 fpm using the AirFoil probe, and 25-2500 fpm using the VelGrid.
- When used with the Series 8400 FlowHood System, this unit measures air flow and may compensate for density and backpressure effects, allowing direct air flow readings from 25-2500 cfm.
- Accurate differential pressure measurements can be obtained from 0.0001 in wc to 60.00 in wc. Absolutepressure measurements range from 10-40 in Hg.
- Temperatures can be measured from -67/ F to 250/ F, either individually, or in conjunction with an air flow or velocity measurement.
It can read English and metric units.
VelGrid
 |
The VelGrid is a 12" square, 16 point, face velocity grid for coil, filter, fume hood and clean room testing. The VelGrid is an accessory especially designed for use in the measurement of general face velocity conditions such as exhaust hoods, HEPA clean room filter outlets, laminar flow work stations, and large filters and coils. Each reading represents the input of 16 velocity points over a one-square foot area.

Pitot Tube & AirFoil
Pitot Tube and AirFoil are accessories used to measure air velocity in the duct. We have 18, 36, 48and 60 length pitot tubes covering all duct sizes.

FlowHood System
 |
This unit ( Fow-Hood 8400 series) measures air flow and may compensate for density and backpressure effects, allowing direct air flow readings in cubic feet per minute (cfm) and litres per second (L/s) corrected for local air density. The measurement range is 25-2500 cfm supply and 25-1500 cfm exhaust. Accuracy is ±3% of reading ±7 cfm from 100 to 2000 cfm.

Hand held rotating vane Anemometer
Anemometer LCA6000VT is used for measuring the average air velocity at the face supply or return air grilles. The air velocity is displayed digitally and the reading is held as long as the button remains depressed.
Velocity range 0.25 to 30 m/sec or 50 to 6000 ft/min. Accuracy ±1% of reading ± 1 digit |

Differential pressure meter DPM 490
 |
DPM 490 digital manometer used for Hydronic Balance is a versatile hand-held operated manometer for positive or positive differential pressure measurement and can tolerate most liquid media compatible with 316LSS.Range of reading is 0-100 psi, and accuracy ±0.5% F.S.
