0.28 inch voltage and temperature dual display waterproof meter
Introduction
1. The watch head is designed with a completely enclosed shell, soaked in water for a short period of time, it can work normally without damage.
2. This meter head can display temperature value and voltage value at the same time.
3. The meter head is small and compact, and adopts three 0.28-inch LED digital tubes for display.
4. Two-wire wiring, simple wiring; direct measurement, without external auxiliary power supply.
5. This meter can be used to detect the battery voltage of motorcycles, automobiles, etc., and grasp the battery status in time.

Note:
1. The power supply voltage used in this meter should not be higher than 18V. Please pay enough margin to the meter to avoid permanent damage to the meter due to motor sparks, power ripple or other excessively high sudden voltages.
2. Because the meter uses LED display, it needs a certain working current, so it can not be used for high internal resistance voltage measurement, such as weak signal voltage, button battery.
3. Pay attention to the wiring method, the red wire is connected positive, and the black wire is connected negative, not reverse.
