The MODEL 473B 100 mm Vane Thermo-Anemometer Test Instrument is a versatile unit that quickly and easily measures air velocity or volumetric air flow, as well as air temperature and humidity in imperial or metric units. A stainless steel 100 mm vane probe is included, which has a comfortable hand grip. The extruded aluminum housing fully protects electronics, yet is lightweight and comfortable to hold.

• Compatible with Dwyer AP1 thermo-anemometer and RP1 thermo-hygrometer wired probes (sold separately)
• Measure air velocity, volumetric air flow, temperature, and humidity with the included 100 mm vane probe
• Visible in any condition due to high contrast and backlit LCD display
• Able to store up to 99 readings for later evaluation
