Digital Coulomb Meter
Digital Coulomb Meter (Product Code: SLE/PHY/156) is a digital instrument used to measure electric charge in nanocoulombs in physics laboratories and electrostatics lessons. It displays up to 1999 nC with an accuracy of ±10 nC, showing the charge deposited into it by a current through a resistance, from a capacitor or from a source of static electricity. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the Digital Coulomb Meter Used For?
Electrostatics is usually taught with leaf electroscopes that only show "more" or "less" charge; a coulomb meter puts a number on it. Students can charge a rod by friction, transfer the charge to the meter and compare materials, or sample the charge on a Van de Graaff generator. With a capacitor, they charge it to a known voltage, discharge it into the meter and use Q = CV to find the capacitance. It is one of the more specialised digital measuring instruments in a school or college physics lab.
Because the stated accuracy is ±10 nC, experiments that deposit charges well above that figure give a smaller percentage uncertainty than very small charges. Work in dry conditions where possible, since damp air lets static charge leak away before it can be measured, and keep readings within the 1999 nC display range.
What to Specify When Ordering
- Number of meters, for teacher demonstration or for student groups.
- The charge sources you plan to use, such as friction rods, a Van de Graaff generator or capacitors.
- Whether you need a calibration certificate — ask us whether one can be provided before ordering.
- Delivery destination in India or abroad.
Supplier
Jain Scientific Equipments Private Limited, which trades as ScienceLab, supplies the Digital Coulomb Meter from Ambala, Haryana, India, to schools, colleges, research laboratories, dealers and institutional buyers. Because the company also supplies the wider range of electrostatics apparatus, a lab can place a single enquiry for the meter and the charge sources it will be used with.

Frequently Asked Questions
What range does the Digital Coulomb Meter measure?
The Digital Coulomb Meter displays charge up to 1999 nC with an accuracy of ±10 nC. That range suits the small charges produced in school and college electrostatics experiments, such as charging by friction or discharging a small capacitor.
Which charge sources can the Digital Coulomb Meter measure?
The Digital Coulomb Meter shows the charge deposited into it by a current through a resistance, from a capacitor, or from a source of static electricity. This makes it useful for both current electricity and electrostatics topics.
How is the Digital Coulomb Meter used to find capacitance?
To find capacitance with the Digital Coulomb Meter, charge a capacitor to a known voltage, discharge it into the meter and read the charge. Dividing the measured charge by the charging voltage gives the capacitance, following the relationship Q = CV.
Is a calibration certificate available for the Digital Coulomb Meter?
Calibration-certificate availability for the Digital Coulomb Meter should be discussed with us before you order. Mention the requirement in your enquiry through our contact page and we will tell you what documentation can be supplied.
