🔧 What Is a Bluetooth Multimeter?
A Bluetooth multimeter is a digital multimeter (DMM) equipped with Bluetooth connectivity, allowing it to wirelessly transmit readings to a smartphone, tablet, or PC. This is typically done via a companion app provided by the manufacturer.
📈 Benefits of a Bluetooth Multimeter
Remote Monitoring
View live readings from a safe distance
Ideal for high-voltage or dangerous environments
Data Logging & Storage
Automatically store measurements over time
Great for troubleshooting intermittent faults or documenting installations
Graphing & Visualization
Many apps display voltage, current, or resistance as real-time graphs
Makes it easier to see trends or spot anomalies
Hands-Free Operation
Position the meter inside a panel, while you monitor data from outside
No need to hold the multimeter and probes simultaneously
Easy Sharing & Reporting
Export logs as PDFs or spreadsheets for reports or compliance records
Some apps allow annotations and project organization
