Product Specification Sheet
LDR Characteristics Trainer (Digital Meters)
Model Number: MT-E098
The LDR Characteristics Trainer (Digital Meters) is a laboratory instrument designed for studying the voltage-current (V-I) characteristics of a Light Dependent Resistor (LDR). Manufactured by Micro Technologies, it features digital meters, regulated power supplies, adjustable illumination, and interchangeable colour filters for accurate experimentation.
Product Specification
The LDR Characteristics Trainer (Digital Meters) is a complete laboratory trainer developed for studying the voltage-current (V-I) characteristics of Light Dependent Resistors (LDRs) under different illumination conditions. Manufactured by Micro Technologies, the trainer enables students to understand the relationship between light intensity and electrical resistance through practical experiments.
Designed for engineering colleges, universities, polytechnic institutes, and electronics laboratories, the trainer provides a fully integrated experimental platform featuring digital meters, regulated power supplies, precision voltage control, and a dedicated optical arrangement.
The trainer incorporates a regulated 10V DC power supply and digital meters for measuring both voltage and current accurately during experimentation. The LDR is mounted on a separate optical unit, allowing controlled exposure to light from a built-in 100W light source.
A wooden optical bench with a graduated scale enables accurate positioning of the LDR and light source. The onboard voltage control potentiometer allows precise adjustment of applied voltage, making it easy to observe the variation in resistance with changing illumination levels.
The trainer also supports experiments using optional colour filters and a lux meter, allowing students to investigate the influence of different light wavelengths and illumination intensity on LDR performance.
Manufactured using a high-quality insulated printed circuit board with clearly printed circuit symbols, the trainer is housed in a rugged ABS plastic cabinet. All experiment points are brought out through 4 mm colour-coded sockets, ensuring safe and convenient laboratory operation.
