Coulombmeter

Product Code : SCL-EI-10676

The Coulombmeter is a physics laboratory instrument manufactured and exported by Lab Glassware Manufacturer, Ambala, Haryana, India, a manufacturer and exporter of laboratory glassware, scientific instruments, and STEM teaching apparatus since 1982. It is used to measure electric charge in electrostatics, charge-transfer, and capacitor experiments, and is supplied to schools, colleges, universities, and STEM laboratories across India and to export buyers in countries including Nigeria, Ghana, Senegal, and Ivory Coast, and across the West Africa region.

Quick answer: A Coulombmeter is a classroom measuring instrument that lets students record an actual numeric value for electric charge instead of only observing electrostatic effects qualitatively. It is typically used alongside electrostatics kits, charged rods or plates, and capacitors to study charge generation, charge transfer, and charge storage. The exact measuring range, resolution, display type, and included accessories vary by unit — check the specific listing before ordering.

Technical Specifications

Applications / Uses

• Measuring electric charge in school and college electrostatics experiments
• Studying charge transfer between charged objects, rods, or plates
• Observing capacitor charging and discharging behaviour with a numeric readout
• Comparing positive and negative charge effects where instrument polarity is supported
• Demonstrating conservation of charge in controlled classroom experiments
• Supporting STEM activities on measurement, data recording, and graphing

How to Use the Coulombmeter

1. Confirm the measuring range, input protection, polarity, and connection method before use.
2. Place the Coulombmeter on a dry, stable, insulated laboratory bench.
3. Check the leads, probes, terminals, display, and power source for damage.
4. Zero or reset the instrument according to the supplied instructions.
5. Connect the approved probe, capacitor, or electrostatic apparatus to the input terminal.
6. Transfer charge carefully and observe the reading on the display or scale.
7. Record readings and repeat trials for comparison.
8. Discharge connected capacitors and electrostatic objects safely after the experiment.

Safety note: Use the Coulombmeter only with approved school electrostatics apparatus and low-energy circuits. Do not connect it to mains electricity, high-voltage supplies, charged capacitors, or unknown circuits unless the instrument's rating and protection are verified.

Care & Maintenance

• Store the Coulombmeter dry and protected from dust, static damage, and impact.
• Keep probes and terminals clean for stable readings.
• Remove batteries before long storage if the unit is battery powered.
• Remove the instrument from use if the display fails, readings drift abnormally, terminals loosen, or the case is damaged.

Coulombmeter and Electrostatics Apparatus: A Complete Measuring Set

A Coulombmeter is a measuring instrument, not a charge-generating apparatus, so it is typically used together with electrostatics equipment that produces or transfers the charge being measured. Schools building a complete electrostatics teaching set from Lab Glassware Manufacturer commonly pair a Coulombmeter with an Electrostatics Starter Kit for general induction and charge demonstrations, a Friction Skin for Electrostatic Experiments for generating charge by friction, and an Influence Machine for higher-charge induction demonstrations. Used together, these let students both generate and quantitatively measure electric charge in the same lesson rather than relying on qualitative observation alone.

Frequently Asked Questions

What is a Coulombmeter used for?
A Coulombmeter is used to measure electric charge in electrostatics, capacitor, and charge-transfer experiments.

What unit does a Coulombmeter measure?
A Coulombmeter measures electric charge in coulombs or related sub-units, depending on the confirmed measuring range of the specific unit.

What is the measuring range of this Coulombmeter?
The measuring range is not confirmed in current product data. Schools should request the measuring range from the product label, datasheet, or Lab Glassware Manufacturer directly before ordering.

Can it be used with capacitors?
Yes. It can be used for capacitor charge and discharge experiments if the capacitor's voltage and charge level are within the Coulombmeter's confirmed input protection limits.

Does it include probes or leads?
Probe and lead inclusion is not confirmed. Schools should confirm the final supplied accessory list with Lab Glassware Manufacturer before ordering.

Is it suitable for school physics labs?
Yes. It is suitable for supervised school and college physics practicals on electrostatics, charge transfer, and capacitor behaviour.
