Product Description Product DescriptionInstant Read Digital Thermometer with Backlit Display for Easy Use 1, OverviewA digital thermometer is an instrument that directly measures the temperature of various liquids and gases, and can measure temperatures within the range of -30~200 oC. It is mainly used as a teaching instrument for middle school physics and chemistry. This instrument adopts a high-precision temperature sensing head and a 4-digit ultra high brightness digital display, which has the characteristics of easy use, high measurement accuracy, small linear error, and clear display. 2, Technical performance 1. Measurement range: -30~+200 oC 2. Measurement error: ± 0.5 oC 3. Display: 4-digit 0.8 '' LED ultra high brightness digital tube 4. Sensing method: direct contact 5. Power supply voltage: AC220V ± 10%, 50Hz 6. Power consumption:<2W 3, Structure and Principle The digital thermometer consists of a main chassis and a test thermocouple, with all internal components installed on a printed circuit board. Simply release the upper and lower covers of the chassis to inspect the instrument. The instrument uses a high-precision humidity sensor and an internal dedicated A/D converter circuit to convert and display the signals sampled by the sensor. The power circuit consists of a power transformer, full wave rectification, and three terminal stabilization to provide various voltage groups for instrument use.Detailed PhotosCompany ProfileCertificationsPackaging & ShippingFAQ
