INTRODUCTION

The TMA-21HV Portable Air Velocity Meter is a lightweight versatile
instrument that can be used anywhere to measure air velocity,
temperature, and relative humidity. It can also calculate the volumetric
flow rate, dew point temperature, wet bulb temperature, wind chill
temperature, humidex temperature and Heat index temperature. The
meter uses a telescoping probe. Applications include hood velocity, clean
rooms, OSHA compliance, ventilation ducts and outlets, heating and air –
conditioning, wind tunnels, product development, air – flow research and
mass – flow measurement in ducts.
