Deskripsi Produk

Accurately measure Air Flow (CFM/CMM) or Air velocity plus °F/°C Temperature

The 407119 Heavy Duty CFM Hot Wire Thermo–Anemometer uses a telescoping probe (extends up to 3 ft) which is ideal for use in ducts and ventilating systems. It can accurately measure Air Flow (CFM/CMM), Air Velocity and Temperature. Air Flow can be displayed as an instantaneous value or up to a 20 point average. Additional functions include Data Hold, Min/Max, and Auto power off. Comes complete with telescoping probe with 5.5ft cable, and 4 x AA batteries.

Features:

  • Air velocity measurements as low as 40ft/min
  • Telescoping probe is ideal for use in ducts and ventilating systems; extends up to 3ft (940mm) long
  • Measures air volume in CFM (ft3/min) and CMM (m3/min) plus Temperature simultaneously
  • Air Flow displayed in 2 modes: Instantaneous value or up to 20 point average
  • Record/Recall MIN and MAX readings
  • Large 1.4″ (99,999 count) LCD display
  • Data Hold plus Auto Power Off
