The TASI-621 thermohygrometer is a handheld, easy-to-use, 31/2-digit (1999 max reading) digital temperature and humidity meter with a robust design. A thermistor is used as an inductor for temperature measurement, while a polymer humidity sensor with varying capacitance is used as an inductor for Relative Humidity measurement.
