             STN LCD Hall Effect Coulometer introduce

     Wooliis Electronic Devices Co., Ltd launched  STN LCD hall coulometer. battery Coulomb meter. Using hall sensor measurement of coulomb meter, can be very simple installation, without considering the power supply ground problem, how to measure how to measure, use Holzer coulomb meter is so capricious. Because Holzer type measurement is isolated measurement, it will not destroy the original original line. It is safe and reliable N times than the general shunt Coulomb meter.
       Using STN full view LCD screen, indoor and outdoor, at night, during the day, under direct sunlight, are clearly visible, can completely avoid the digital tube watch under the sun is not clear drawbacks. Full screen simultaneous display of all information. True residual capacity meter. Display of voltage, current, power, electric energy and electric energy. Suitable for all kinds of lead-acid batteries, and lithium polymer and lithium iron phosphate battery, strongly recommend the use of coulometer. The capacity table with a rough estimate of the voltage can be completely avoided.
