Product Details

We are known as one of world's leading China manufacturers and suppliers. Welcome to buy the famous brands' owom 4 1/2 digital multimeter with bluetooth, multimeter test, digitale multimeter, bluetooth multimeter, 22000 count multimeter with cheap price from us. We have many products in stock at your choice. Consult the quotation with us now.

1. more than 1 device could be monitored, assuring more measurement safety

Several units DMMs possibly communicated with mobile app, freeing people from touching the measured object, human safety fully guaranteed.



2. functioning as multimeter + datalogger

The measured data always updated, and auto- recorded to mobile device, saving labor to do on-site records; the recoding duration, and sampling duration could be customized, accessible in chart mode, facilitating comparison analysis between several DMMs.



3. Offline record function

User don’t have to leave the phone on measure site, just use App to set the record interval and sum points. Multimeter will record the data itself and store them in its memory. Load the data from multimeter when there is analysis requirement.
