Professional anemometer works with a 3-cup velocity probe and directional probe Model : AM-4836C
AM-4836C: 3-cup velocity probe and directional probe – เครื่องวัดความเร็วลม แบบถ้วย และทิศทางลม
This professional anemometer (AM-4836C) works with a 3-cup velocity probe and directional probe for collecting various data with high accuracy. The useful device can determine and memorize 24 groups of following data: air velocity, air flow, Beaufort Scale, Wind Direction, Wave Height and Air Temperature.
Features:
- LCD display: 4 digits, 0.5″ (13mm) LCD
- Measurement units
a. Air Velocity: m/s, km/h, ft/min, knots
b. Air Flow: CMM (m3 / min) ; CFM (ft3 / min)
c. Beaufort Scale: Force
d. Wave Height: m
e. Direction : ° from the North direction
f. Temp: °C and °F - Data hold: Maximum value
- Can memorize 24 groups of obtained data and be able to recall from the meter at anytime.
