Product Overview
IN80 hot film  Air speed sensor for clean environment is an ideal choice for measuring  Air speed in the field of precise ventilation control. Based on the working principle of hot film type, the product can still maintain high accuracy even at low  Air speed. The product has added an anti drift design. Factors such as temperature change and vibration will not affect the performance of the sensing element basically. The long-term stability of the product has been greatly improved, and its reliability is far higher than that of the traditional hot wire anemometer.
