Review on 🔧 OWON OW18B Digital Multimeter Bluetooth Data Logger with NCV, True RMS, Flashlight, and Temperature Test - Includes K-type Thermocouple by Mark Jefferson

Now maybe the recorder works with IOS phone after data logging with two Android phones just didn't work. The multimeter connected to the Android app and registration commands were sent to the multimeter but when trying to get data nothing was entered into the app. Since I only needed to record DC voltage (RV batteries) I bought this to replace that meter.
