Sensor suhu/kelembapan duct (Model HTY78_5 series) adalah sensor dengan presisi dan keandalan tinggi yang menggunakan resistance temperature detector (Pt100) sebagai sensor suhu dan polymer capacitive humidity detector (FP5)* sebagai sensor kelembapan.
Dengan rentang pengukuran yang luas dan stabilitas yang sangat baik, sensor ini dapat digunakan untuk berbagai aplikasi industri seperti pengukuran udara luar, serta digunakan pada duct, chamber, dan sebagainya pada bangunan umum untuk sistem tata udara.
