A battery operated direct reading analogue anemometer with 100 mm diameter vane head and telescopic handle. Three ranges to measure from 0.25 to 25 m/sec.
Features
The EDRA 6 is an electronic anemometer providing virtually instantaneous readings of air velocity in m/sec and ft/min on a large, clear analogue meter. The display has three user selectable measurement ranges, colour coded for ease of reading, to ensure excellent resolution particularly in critical low velocity situations.
Using the industry standard 100 mm (4") rotating vane a variety of applications can be measured quickly and accurately. The outstanding versatility of EDRA 6 is further enhanced using the telescopic extension handle which provides rigid support of the vane sensor up to 1.1m in length. Incorporating a lockable 'all angle' swivelling tip, alignment of the sensor in the air stream is possible even where access is limited.
Contained in a durable moulded plastic enclosure, EDRA 6 is supplied complete with a protective carrying vase, designed to withstand the rigours of on-site use, with ample storage space for accessories and documentation.
An extremely helpful option is the Aircone kit. An inexpensive kit containing a circular and rectangular moulded hood for air balancing which simply clips onto the vane probe to provide direct air volume flow readings from grilles and diffusers.
