Lutron รุ่นSP-7000เครื่องวัดความเร็วลมมัลติฟังชั่น(7-in-1),Air velocity/Temp,Humidity/Temp, Air flow,Dew point,Wet bulb,Wind chill,Heat index.

Lutron 7-in-1 environment meter measures air speed, CFM, humidity, temperature, heat index, wind chill, dew point and wet bulb temperature.

• Mini pocket environmental conditions meter.
• Memorize the maximum and minimum value with recall.
• Hold function to freeze the current reading value.
• °C / °F selectable.
• Compact bone shape with lightweight and small size case design.
• Wristlet design provides extra protection to the instrument especially for one hand operation.
• Low-friction ball bearing mounted wheel design provides high accuracy at high and low air velocity.
• Low battery indicator.
• Auto power off (can be disabled).
