Hot Wire Anemometer SK-73D SK SATO

Hot Wire Anemometer SK-73D SK SATO

Telescoping probe air velocity and temperature meter for precise HVAC and ventilation diagnostics

The SK SATO SK-73D Hot Wire Anemometer is a high-performance digital instrument designed to measure both air velocity and temperature with precision and convenience. Using a hot wire sensor (Pt thermistor), this device is ideal for low-speed airflow measurements and offers automatic temperature compensation for more accurate results.

Equipped with a telescopic probe that extends up to 930 mm and a 2-meter cable, it allows users to safely and comfortably access overhead vents, ducts, or confined spaces without compromising accuracy. The lightweight and ergonomic design make it suitable for both industrial professionals and field engineers.
