How Does It Compare with Other JLab Light-Sensor Apparatus?
| Model | Device studied | DC supply (as listed) | Experiment as listed |
|---|---|---|---|
| This apparatus (EL-OED-1053) | LDR | 0–3 V DC / 100 mA | Current versus light intensity at different voltages |
| Photodiode Characteristics Apparatus | Photodiode | 0–10 V DC / 50 mA | Current versus light intensity at different voltages |

Choose the LDR apparatus when the practical is about photoconductivity and light-controlled resistance. The photodiode and phototransistor units cover the semiconductor junction detectors, and the opto-electronic devices kit puts three devices on one panel for labs that want a single combined trainer.
What Is the LDR Characteristics Apparatus Used For?
A light-dependent resistor is a photoconductive sensor, typically made of cadmium sulphide, whose resistance falls as the light on it increases. With this apparatus students set a voltage on the regulated supply, change the light reaching the LDR from the light source, and record the current on the meter at each light level; repeating at several voltages gives a family of curves. The current rises with light intensity, and at any fixed light level it rises in proportion to the voltage, so students see that the LDR behaves as a resistor whose value is set by the light.
The experiment fits B.Sc. physics and electronics practicals, polytechnic and ITI electronics courses and senior secondary projects on sensors. It explains everyday circuits such as automatic street lights, night lamps and light-activated alarms, and leads directly to the photoelectric relay experiment, where an LDR switches a load. Keep the bench lighting steady while taking readings, allow the LDR a few moments to settle after each change of light, since these sensors respond slowly, and return the supply to zero before changing connections.
What to Specify When Ordering
- Quantity — the minimum order is 10 units; labs often order it with the photodiode and phototransistor units to cover a full opto-electronics practical.
- Light source and intensity control — the listing does not say how the light level is varied or measured, so confirm the arrangement in the quotation.
- Mains supply — state your lab’s voltage and plug type so the power supply can be confirmed.
- Connecting leads and spare LDRs — ask for them in the same enquiry if your benches need them.
Frequently Asked Questions
What does the LDR characteristics apparatus measure?
The current through a light-dependent resistor as the light intensity changes, at several fixed voltages. The resulting curves show how the LDR’s resistance falls as light increases.
What power supply and meters are built in?
A DC regulated power supply of 0–3 V DC at 100 mA and two round meters, one for voltage and one for current. The LDR is mounted on the panel and its connections are brought out to terminals.
Is a light source included?
Yes, the apparatus is listed with a light source. The listing does not detail how its intensity is set, so ask JLab to confirm the arrangement if your practical needs a specific method.
How does an LDR differ from a photodiode?
An LDR is a photoconductive resistor with no junction, so it conducts equally in both directions and reacts slowly. A photodiode is a semiconductor junction that responds much faster; JLab lists a separate photodiode characteristics apparatus.
What should an export enquiry include?
The quantity, destination country and port or city, preferred delivery terms such as FOB or CIF, packing or labelling instructions, and the tender reference if one applies.
Who manufactures this apparatus?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, builds it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an electronic lab instruments manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The panel, regulated supply and meter wiring of this unit are assembled at JLab’s own works rather than bought from a trader, so colleges, institutes, dealers and importers buy factory-direct; each unit is visually inspected before dispatch, and repeat orders and service questions return to the same team. JLab exports worldwide and ships to buyers in every region — for example Hong Kong in East Asia, Norway in Northern Europe, Zambia in East Africa, Kazakhstan in Central Asia and Guyana in South America. Tender details are on the JLab lab tenders page.
