Part No. 473B-1 | Air Velocity Range: 40-5000 ft/min (0.2-25 m/s), ±1.5% rdg
The Dwyer 473B-1 combines air velocity or volumetric flow, air temperature, and humidity measurements in one handheld instrument, making it suitable for HVAC testing, balancing, and duct traverse work.
Its 100mm stainless steel vane probe features insertion-depth markings for consistent positioning inside ducts. The probe connects through a coiled cable that extends from 28" retracted to 6 feet, providing flexible reach during field measurements. The ergonomic aluminum enclosure is designed for repeated field use.
Air velocity is measured from 40-5000 ft/min (0.2-25 m/s) with ±1.5% of reading accuracy, while humidity accuracy is ±2% at 77°F. A 4.5-digit backlit LCD keeps measurement results visible in dim mechanical rooms, and the instrument can store up to 99 readings for multi-point duct traverses.
The 473B-1 supports imperial and metric measurement units, allowing technicians to select the format required for their application.
Need a different spec? The Dwyer range also includes the VP1 replacement 100mm vane probe for the Model 473B. This can be used when a replacement probe is required for a compatible 473B instrument.

Frequently Asked Questions
What does the Dwyer 473B-1 measure?
The 473B-1 measures air velocity or volumetric flow, air temperature, and humidity in imperial or metric units.
What is the air velocity range of the 473B-1?
It measures air velocity from 40-5000 ft/min (0.2-25 m/s) with ±1.5% of reading accuracy.
What type of probe does the 473B-1 use?
It uses a 100mm stainless steel vane probe with insertion-depth markings.
How long is the probe cable?
The coiled cable extends from approximately 28" when retracted to 6 feet when extended.
How many readings can the 473B-1 store?
The instrument can store up to 99 readings.
Is a replacement probe available for the 473B-1?
Yes. The VP1 is the matching 100mm replacement vane probe for the compatible Model 473B.
Does GeneralTech Shop deliver the 473B-1 across the UAE?
Yes. Call +971 6 5436933 and our team will confirm delivery availability and timelines for your emirate.
Should I choose the 473B-1 or the VP1?
The 473B-1 is the complete vane thermo-anemometer, while the VP1 is the replacement 100mm vane probe. If your compatible 473B instrument requires a replacement probe, the VP1 is the relevant part.
