Axial AC Fan for SIGMA II Series Reorders
Use an external fan for faster response and more accurate
measurement. It is in combination with this fan that the maximum
capability of measurement for temperature and humidity can be achieved.
The fan inhales fresh air into the instrument and makes the response of
sensor faster, resulting in the detection of accurate data. It is
effective, particularly in warehouses which are excluded from the open
air, laboratories where ventilation is poor or air tight small space.
