Dwyer Model 471B-1 Thermo-Anemometer Test Instrument
$0.00
Digital Thermo-Anemometer, 9v Battery, Probe, Wrist Strap, Soft Carry Case
Measures Air Velocity or Air Volume and Temperature Simultaneously
The MODEL 471B Thermo-Anemometer Test Instrument is a versatile dual function unit that quickly and easily measures air velocity or volumetric flow as well as air temperature in imperial or metric units. A stainless steel probe is included, which has a comfortable hand grip and etched insertion depth marks. The extruded aluminum housing fully protects electronics, yet is lightweight and comfortable to hold.
Product Applications
- Duct traverses
- HVAC inspections
- Testing and balancing
