The instrument uses a silicon piezoresistive digital air pressure sensor to measure atmospheric pressure. The structure is simple and reliable, low power consumption and light weight, and can be powered by a dry battery or by a matched regulated DC power supply. It has good vibration resistance and is easy to transport. Suitable for laboratory, factory, mine, etc. for atmospheric pressure measurement, especially suitable for field portable applications 1. Air pressure measurement range: 1070.0hPa ~ 500.0hPa 2. Air pressure measurement resolution: 0.1 hPa 3. Air pressure measurement accuracy: (three types Grade) Class A: ±0.3 hPa Class B: ±0.5 hPa Class C: ±1.0 hPa 4. Operating environment: Temperature: -15°C～+50°C Humidity: <90%RH 5. Instrument power supply: Voltage: 5.0V～ 3.3VDC (5V 1.5V dry battery or 5V regulated DC power supply) Power consumption: <7mA (power-on state) <2uA (power-off state) 6. Instrument shape: 190mm × 135mm × 62mm 7. Instrument weight: 360g
Cinnabar also called zinnober. Because the ancient Chenzhou (now Yuanling) produced by called cinnabar. In fact, this does not produce Chenzhou cinnabar, but cinnabar distribution center! Its origin concentrated in Guizhou Tongren, Wan Hill. Mainly used in military industry, scientific instruments, folk also large amounts used in architectural decoration, Buddhism, funeral and other industries. Such as: paint additives, Marine coatings, inkpad, dyes, pigments, painting, calligraphy, decorations, gifts, handicrafts, cosmetics, collection, funeral, buddhist supplies, buddhist scriptures made etc.
