Ventilation Testing and Balancing

The Testo 440 is an accurate vane probe anemometer. Robust and water resistant, this instrument is suitable for all measurements of air velocity in the range 0.2 to 40 m/s.
The large two line display can be easily read at a glance. This instrument is ideal for spot measurements and average readings over time or a number of positions.

The Alnor Electronic Balometer system is designed to measure supply or exhaust air flow from diffusers or grills in HVAC systems. The assembly consists of a meter, nylon hood, handles, and a base. The meter has a digital readout of volume flow and temperature when used with a Balometer base. The range of measurement spans from 50 to 2000 CFM (85 to 3400 m3/h or 24 to 945 l/s) and 32ºF to 122ºF (0ºC to 50ºC). The meter sums and averages air flow up to 100 points.

This pocket sized direct read unit measures:
0 to 4000 ft/min (0 to 200 m/s).
Temp range:
0 to 200 Farenheit
-18 to 93 Celsius

With their remarkable accuracy and extraordinary features, TSI's VelociCalc instruments are ideal for clean room studies and general air velocity tests. A simple touch of the Velocity or Temperature key gives you the measurement you need instantly. These microprocessor-based units can also average up to 255 readings for more comprehensive measurements.

The Model 8345/46 VELOCICALC measures air velocity and temperature and calculates volumetric flow rate. The VELOCICALC can compute
statistics for groups of readings.
