Smart Sensor AR867 LCD Digital Hygrometer Thermometer Dual Humidity Temperature Meter Indoor Outdoor Tester Weather Station with Calendar & Clock Alarm

SMART SENSOR Temperature Humidity Meter is an instrument used for measuring the moisture content in the . Humidity measurement instruments usually rely on measurements of some other quantity such as temperature, pressure, mass or a mechanical or electrical change in a substance as moisture is absorbed. By calibration and calculation, these measured quantities can to a measurement of humidity. Features: Electronic devices use changes in electrical capacitance or resistance to measure humidity differences. Large-character LCD display, clear to read. Low power consumption and high stability & accuracy. Display temperature, humidity and time simultaneously. Display indoor temperature, outdoor temperature& indoor humidity. Freezing point alarm at -1℃~4℃。 ℃/℉ unit selectable, 12 hour / 24 hour displaying system selectable. Memory of MAX & MIN measuring value. Clock & Calendar function, 8 minutes snooze function, desk-top placing or wall hanging. Adopts ABS new engineering plastics, good toughness and rigidity, safer and wear-resistant.
