473B – Thermo vane anemometer (100 mm)
Measures speed, flow, temperature and humidity simultaneously.
Product details
The 473B Hot Wire Thermo-Anemometer is a versatile dual-function instrument that easily measures velocity, volumetric flow, temperature and humidity in metric or English units. High contrast LCD display shows the two selected values simultaneously. Backlight for low light environments. Automatic backlight shutdown after 2,5 minutes to conserve battery power. Low battery warning. Stainless steel probe with convenient knob and probe insertion depth markings from 0 to 20 cm (0-8″). Aluminum case for digital indicator. Up to 99 readings can be stored for later analysis. Protective sled on hot wire sensor used to protect sensor when not in use. Supplied with each 473B Anemometer is a 9V battery, remote probe, wrist strap, and soft carrying case.
