Volt meter 0.28 inch ultra-small digital DC แบบสายสามเส้น โวล์ท มิตเตอร์ ดีซี digital display, adjustable, two-wire DC 0-100V reverse connection protection By KPRAppCompile

Digital Volt Meter ดิจิตอลโวลต์มอเตอร์ จ่ายไฟเส้น +แดง, -ดำ 4-35V สีขาวใช้วัดไฟได้ 0-70V For Arduino NodeMCU Wemos By KPRAppCompile Product Description Function introduction: 1. Range: 0-100V (Red, Blue, Green, Yellow) 2. Equipped with two wires, the wiring is convenient and simple, and it is convenient to connect to the car/battery car/ Motorcycle internal circuit; 3. With reverse connection protection function, the wire will not be burned when reverse connection, with fine adjustment function; 4. Note that the high input voltage cannot exceed 100V, otherwise there is a danger of burning. 5. When the voltage is lower than 0V, the display brightness will dim, but it will not affect the correct measurement. 6. When measuring voltages below 10V, two decimal places are displayed; when measuring voltages above 10V, one decimal place is displayed. It can not only take care of the battery user's need for measurement accuracy, but also take care of the need for measuring higher voltage. Working voltage: DC 4~35V (สายแดงบวก สายดำลบ) Detection voltage: DC 0~70V(สายสีขาว) Working current: <30mA Display mode: 0.28" LED, red blue green yellow (color optional) Measuring rate: ≥200mS/time Measurement accuracy: 3‰ Extreme working conditions: Low working voltage: + 0V Is high working voltage: + 100V Working temperature: -10~+65℃ Working humidity: 10~80% (no condensation) Working pressure: 80~106kPa Sun exposure: no direct exposure It is a good measurement accuracy, this voltmeter will automatically move the position of the decimal point according to the difference of the measured voltage. When measuring voltage below 10V, two digits will be displayed after the decimal point; When measuring voltage greater than 10V, one digit after the decimal point is displayed. It can not only take care of the battery user's need for measurement accuracy, but also take care of the need for measuring higher voltage. This voltmeter can be used to measure the voltage of 18650 batteries, mobile phone lithium batteries, nickel-hydrogen battery packs and other battery packs. As well as the battery voltage of motorcycles and automobiles, it can also be used for other voltage measurement purposes #volt, #volt meter
