เครื่องวัดความเร็วลม SM-28

SkyMate has been a best-seller for 10 years! Convenient pocketknife design, features, accuracy, and price make this a great value in a handheld unit. Unlike other wind meters, the pocketknife case allows more precise wind speed readings because the users hand is distant from the wind impeller, which then measures undisturbed air flow. SkyMate is water resistant, floats, has a high-visibility case, and tripod fitting. For the most precise measurements, it can be used with our wind tunnel, Model SM-WT.
