Dual digital voltmeter and ammeter for DC systems Key benefits Simultaneous voltage and current monitoring: Dual digital display shows voltage and current at the same time so you can quickly assess system status without switching meters. Wide measurement range and flexible current options: Measures DC 0–300 V and is available with Hall-effect current sensors in 50 A, 100 A, 200 A, or 400 A versions to match different systems. Accurate, reliable readings: Hall-effect sensing delivers stable, contactless current measurement and dependable data for electrical system monitoring and fault detection. Easy to read, even at a distance: The bright digital readout displays clear numbers for fast visual checks during operation or troubleshooting. How this helps you Prevents damage and downtime by making abnormal voltage or overcurrent events visible immediately. Simplifies system diagnostics and maintenance with simultaneous, accurate readings. Lets you choose the current range that fits your installation, avoiding oversizing or undersizing measurement capability.
