| Model 5725 |
| Features and Benefits |
| • Reversible 4-inch (100 mm) head to read supply and
exhaust flows • Calculates volumetric flow rate when user inputs duct shape and size, or area • Sampling function records multiple point measurements • Automatic averaging of air velocity • Simultaneously displays velocity and temperature • Sweep mode for one overall measurement • Optional 36-inch telescopic probe available • Compatible with optional Aircone flow hoods Data Logging Features • Logs 12,700+ samples with a time and date stamp • Recall, review, store data • LogDat2™ downloading software included |
| The VELOCICALC 5725
is a high performance, yet simple to use, rotating vane anemometer. High
accuracy and reliability make the VELOCICALC 5725 the professional’s
ideal tool for measuring unevenly distributed or fluctuating flows through
heating and cooling coils, diffusers, grilles, and filters. It accurately measures air velocity and temperature, calculates flow rate, performs averaging, and can determine minimum and maximum readings. Using sweep mode you can quickly provide one averaged reading of velocity or volume over a large measurement area. The large vane head automatically averages velocity and volume readings. The VELOCICALC 5725 includes variable time constant, sampling and statistics functions and data logging capability. Applications • Heating and cooling coil analysis • Diffuser and grille measurements • Fume hood face velocity tests • Indoor air quality tests • Filter face velocity measurements |

| Aircone Flow Hoods | |
Aircone
Flow Hoods are a fast and accurate method of maximizing the usefulness
of your 4-inch (100-mm) rotating vane anemometers. For a modest investment,
you can enhance the capability of your rotating vane, turning it into
an air volume flow balancing tool. |
|
| Features and Benefits | |
| • Rectangular and circular
cones available • Measures volumetric flow at grilles, diffusers, and linears • Reads air volume quickly and accurately • Excellent choice for small grilles |
