LDR Characteristics Apparatus (Analog Meters)
Model Number: MT-E098A
The LDR Characteristics Apparatus (Analog Meters) is a precision laboratory instrument designed for studying the voltage-current (V-I) characteristics of Light Dependent Resistors (LDRs). Manufactured by Micro Technologies, it features analog meters, a regulated DC power supply, a dedicated optical setup, and a precision optical bench for semiconductor experiments.
Product Specification
The LDR Characteristics Apparatus (Analog Meters) is a laboratory trainer developed for studying the V-I characteristics of a Light Dependent Resistor (LDR) under different illumination conditions. Manufactured by Micro Technologies, the apparatus enables students to investigate the relationship between light intensity and electrical resistance through practical laboratory experiments.
Designed for engineering colleges, universities, polytechnic institutes, technical training centres, and electronics laboratories, the apparatus provides a complete experimental setup with analog measuring instruments, regulated power supply, and an adjustable optical arrangement for accurate observation.
The trainer incorporates a regulated 0–10V DC power supply that delivers stable voltage for the experiment. Built-in analog voltmeter and analog ammeter enable precise monitoring of voltage and current during LDR characteristic studies.
A dedicated LDR unit is mounted on a wooden optical bench with engraved scale, allowing accurate positioning relative to the 100W light source. The applied voltage is controlled using an onboard precision potentiometer, enabling smooth variation of voltage while observing changes in LDR resistance.
The apparatus also supports optional colour filters for studying spectral response and an optional lux meter for measuring illumination intensity. Manufactured using a high-quality insulated printed circuit board with clearly printed circuit symbols, the trainer is housed in a durable ABS plastic cabinet. All experimental terminals are brought out through 4 mm colour-coded sockets for safe and reliable laboratory operation.
