 TA5 Thermal Anemometer

A MEASURABLY BETTER METER?

 

Airflow?s TA5 Thermal Anemometer is the 'State Of The Art' in portable air velocity and temperature measurement.

Measurements are automatically temperature compensated up to 80C. This allows optimum accuracy to be displayed at all times across a wide velocity range, and when two ranges do overlap, accurate readings will continue to be displayed with a built-in neon indicator lighting to alert the operator that a more suitable range can be selected. The neon also acts as a warning in the unlikely event of a problem occurring in the rugged but slim telescopic probe, thus avoiding the possibility of any misleading readings.

The slim, telescopic probe is available with either a rigid (standard) or articulating (optional) all angle tip for outstanding on-site versatility in limited access positions. The superb yaw and pitch (see tech topic I001)characteristics of the AirflowTM thermistor bead probe design also allow accurate, repeatable readings to be maintained, even up to 15 from the airstream centreline.

Both imperial (Ft/min, F) or metric (M/sec, C) units can be selected at the press of a button and automatic electronic zeroing ensures very accurate readings are maintained with minimal zero drift. Another outstanding feature unique to TA5 is the bar graph velocity indicator which provides an instantaneous 20 step display of unstable flow conditions, an important consideration when traversing in ducts. An analogue output is also provided so that measured values may be downloaded onto compatible printers or Data Loggers.

In recall mode the exceptional capability of TA5 is revealed. Up to 99 individual velocity and temperature readings may be simultaneously memorised, stored and displayed together with their average, minimum and maximum values. All stored readings may be recalled and reviewed on the display for time saving on the spot analysis of velocity and temperature distribution.

Calibrated to an Internationally recognised standard the TA5 is supplied with a FREE TRACEABLE CERTIFICATE OF CALIBRATION and a reply card is also included for purchasers to register with our FREE annual calibration reminder service.

All Airflow instruments, including the TA5, are designed to help meet the stringent requirements of the Control Of Substances Hazardous to Health (COSHH) and Building Regulations in the UK.

For our UK customers the reminder card service ensures valid certification for COSHH, ISO9001 and Quality Assurance requirements.
