 OWON OW Series NCV Multimeter

OWON Digital NCV Multimeter with Bluetooth is the branch of OWON's handheld multimeter series. With smaller size and faster reponse rate. Support NCV, True RMS, bluetooth communication. Can be used as Data Logger, Multimeter and Thermometer. Contact us for more detail information!BLE 4.0 wireless transmission, support muti-devices connection and  single-display monitoring.One mobile end can connect with multiple multimeters,  the test object is totally isolated with user to secure their life.Not only a multimeter, also a data logger and thermometer.Real time data are updated and recorded to end  user device, no need to be in field. User can define  the record time and sampling gap, data can be shown  as chart and diagram, multi-devices connection  supports data comparison.   User and test object are totally isolated,  which secure the life.Build-in offline record function.No need to put the end device in field, multimeter will save the data in its memory.  Use the smartphone to load the data when connected.Large display with flashlight.Large display with high brightness flashlight.  Can implement the test among darkness.NCV non-contact voltage sense.While getting the non-contact voltage sensor close to conductor,  the instrument will beeps and flash with the frequency according to  AC voltage strength.Support temperature test
