Ammeter DC Dual Range OHP
The Ammeter DC Dual Range OHP (Product Code: SLE/PHY/01) is a dual-range, DC-only ammeter manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for school and college physics laboratories. Built into a transparent case, it is designed to sit directly on an overhead projector (OHP) so the needle and scale stay visible to a full classroom during demonstrations — a practical alternative to a standard bench ammeter for group teaching of physics lab equipment.
Specifications
| Parameter | Detail |
|---|---|
| Type | Moving-coil ammeter, DC only |
| Ranges | 0–0.5A and 0–2.5A (dual range, single scale) |
| Accuracy | ±2.5% |
| Case | Transparent, OHP-projectable housing |
| Additional features | Magnetic shielding and dampening for stable readings |
Typical Use
This ammeter is used wherever a class needs to read live current together rather than crowd around a bench meter — Ohm’s law demonstrations, series/parallel circuit teaching, and other core physics lab equipment sessions in schools and colleges. The dual 0–0.5A/0–2.5A range covers both low-current and higher-current classroom circuits without swapping instruments, and the magnetic shielding keeps the reading stable near other electrical apparatus on the same bench.
Manufacturer
The Ammeter DC Dual Range OHP is manufactured by Jain Scientific Equipments Private Limited, which trades under the brand ScienceLab. The company is based in Ambala, Haryana, India, with its registered office and manufacturing unit in the Ambala district.

Frequently Asked Questions
Who manufactures the Ammeter DC Dual Range OHP?
It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), based in Ambala, India — a physics lab equipment and laboratory instruments supplier to schools, colleges and technical institutes.
Why does it have a transparent case?
The transparent housing lets the meter sit on an overhead projector so the scale and needle movement are visible to the whole class during demonstrations.
Can this ammeter measure AC current?
No — it is a moving-coil instrument designed for DC current only.
Is bulk or institutional supply available?
Yes, this product can be supplied in bulk to schools, colleges, and distributors; contact us for quantity and export enquiries.
How are the two current ranges selected?
The meter offers 0–0.5A and 0–2.5A on a single dual-range scale. The exact terminal/selector configuration is confirmed on the datasheet — contact us if you need this before ordering.
What is the smallest scale division on each range?
Scale graduation isn’t listed in our current product documentation for this item; contact us for the detailed datasheet.
Are connecting leads included?
No, connecting leads are supplied separately — see Stackable Leads or Crocodile Clips & Leads in our Physics Lab Equipment range.
Is a calibration certificate available?
Calibration certificate availability depends on the order — contact us to discuss requirements for institutional or bulk purchases.
What is the warranty?
Warranty terms are confirmed at the time of quotation — contact us for current terms.
Can the instrument be used without an overhead projector?
Yes. The transparent case is an added feature for OHP projection; the meter works as a standard DC ammeter on any bench without a projector.
What information is required for an institutional quotation?
Please share the quantity required, delivery location (India or export destination), and any customisation needed via our contact form or enquiry cart, and we will follow up with pricing and lead time.
