Digital Voltmeter
Product Code : LSK-PL-10323
Digital Voltmeter (SKU LSK-PL-10323) is a battery-powered DC voltmeter with a large LCD screen that reads potential difference from 0 to 20 V. Its light, portable design suits Ohm's law, cell and circuit practicals in school physics from Class 10 upward and in college electricity labs. Electricity labs, training institutes, tender contractors and distributors can have the meter quoted by Science Lab Supplies in Ambala, India, alongside other instruments for the same bench.

Applications and Experiments for the Digital Voltmeter
The voltmeter is connected in parallel across a component to read the potential difference between two points of a DC circuit. School battery circuits sit inside its 0–20 V range, and the digital display removes the parallax and scale-reading errors of a pointer meter.
- Class 10 electricity: verifying Ohm's law by plotting V against I for a resistor.
- Class 12 current electricity: measuring the terminal voltage of a cell, for example the 1.5–6 V outputs of a Cell Holder.
- Comparing potential differences across resistors in series and parallel, with values switched in on a Resistance Substitution Box.
- Checking the output of low-voltage DC supplies and battery packs before a practical.
Standard Scope of Supply
Each Digital Voltmeter is supplied as a single unit with its 9 V battery included and pre-installed. Connecting leads can be added to the same enquiry, and the quotation will then show them as a separate line item next to the meters.
Packing, MOQ and Lead Time
Ask for one voltmeter or a set for every workstation in the electricity lab; the quotation you receive gives the packing, delivery time and price for that exact quantity. Ammeters, leads and other physics lab equipment in India can be added so a whole circuits bench is priced at once.
Holding an Importer-Exporter Code as a registered exporter, Science Lab Supplies is able to ship to buyers in Uganda, the UAE, Saudi Arabia, Oman, the Philippines and Nepal. A list of meters per workstation can be posted through the contact page or built up in the enquiry cart, and the lab tender page explains how tendered orders are quoted.
Frequently Asked Questions
What voltage range does the Digital Voltmeter cover?
It reads 0–20 V DC. That range covers cells, battery packs and low-voltage supplies up to 20 V in school and college circuit experiments, shown on a large LCD.
Does the voltmeter need a mains supply?
No. It operates on a 9 V battery, which is included and pre-installed, so the meter can be used on any bench without a mains connection.
Who supplies the Digital Voltmeter?
Quotations for this voltmeter come from Science Lab Supplies in Ambala, India, which also arranges the packing and dispatch, whether the order is one meter or a set for every circuits bench.
Can it measure AC voltage or current?
It has a single 0–20 V DC range. For current, pair it with an ammeter, or use a multimeter where several quantities need to be measured on the same bench.
