Read voltage directly in any classroom circuit

The Digital Bench Voltmeter measures DC voltage across circuit elements without asking students to configure anything first. Connect the banana plug leads to the measurement points, read the display, and record the value. No mode dial to set, no range to select — one function, clearly displayed.

In introductory electricity labs, multimeters create confusion that has nothing to do with the physics being taught. This meter removes that layer. The large digital display is readable from across a lab bench, and the 50-minute auto-off circuit keeps the battery going between class periods without requiring students to power it down manually. An LED indicator signals when a battery replacement is coming due, so readings don't go soft without warning. The ABS and PVC housing handles routine lab use. A 9V battery is included.

Why Teachers Love It

Single-Function Design – With only voltage to measure, students stay focused on the circuit concept rather than troubleshooting instrument settings.
50-Minute Auto-Off – The meter shuts off automatically between uses, extending battery life across multiple class periods without any student action required.
LED Low-Battery Warning – A dedicated indicator lights before readings become unreliable, so you know to swap the battery before it affects lab data.

What You Can Teach with the Digital Bench Voltmeter

Grades 6–8 (Middle School)

Voltage as the driving force behind current in a circuit
Measuring potential difference across individual components in series and parallel circuits
Comparing voltage readings across branches of a parallel circuit

High School Physics

Ohm's Law: measuring voltage to calculate resistance using V = IR
Kirchhoff's Voltage Law: confirming that voltage drops around a loop sum to zero
Measuring terminal voltage vs. EMF to study internal resistance of a battery
Voltage divider circuits and how resistance ratio determines output voltage

AP Physics / Advanced Investigations

Quantitative RC circuit analysis: voltage as a function of time during charging and discharging
Systematic error analysis: how input impedance (10 MΩ) affects measurements in high-resistance circuits
Comparing theoretical vs. measured voltage across varying load resistances

Pair with the Digital Bench Ammeter

Run Ohm's Law and Kirchhoff's Laws labs with a dedicated meter for each quantity. Students measure voltage and current simultaneously across components, keeping data collection clean and avoiding the re-wiring errors that come from sharing a single multimeter between measurements.

Ohm's Law verification – Measure V and I at the same time across a resistor; calculate and compare resistance values across a range of settings.
Kirchhoff's Laws – Confirm that voltage drops sum to source voltage (KVL) and that currents into a node equal currents out (KCL) in one lab setup.
