The AM-4204 is a portable hot wire anemometer used for very low air velocity measurement. The microprocessor circuit provided maximum possible accuracy. The large dual function LCD screen allows for simultaneous viewing of both air velocity and temperature. This meter also comes equipped with RS232 PC serial interface. Temperature range is 0ºC to -50ºC (32ºF to -122ºF). Air flow range is 0.7km/h-72.0km/h.
