Description
Thermal physics and heat-transfer experiment system
Enquire about the LETI-40 for a thermal physics laboratory requiring experiments in heat conduction, specific heat, metal expansion and temperature control, subject to the selected module. Share the experiments and number of student workstations required. Ask for a module-by-module quotation identifying the control unit, sensors, specimens, accessories and manuals; confirm current module availability rather than assuming future expansion items are included.
Laboratory equipment enquiries across Jharkhand and West Bengal
Dhanbad Sales welcomes enquiries from individual buyers, schools, colleges, universities, training centres, research and industrial laboratories, healthcare education providers, NGOs and government institutions throughout Jharkhand and West Bengal. Product suitability is assessed against your specific teaching or laboratory application.
Share your specification or syllabus, quantity, budget, delivery city and PIN code, and required timeline. Identify any setup, demonstration, calibration or documentation requirements separately. Exact specifications, included accessories, current availability, price, applicable warranty and delivery or support feasibility are confirmed in the quotation. No certification, calibration service or manufacturer authorisation is implied unless confirmed in writing.

Introduction
The LETI-40 apparatus is designed to provide comprehensive insights into heat-related experiments, combining multiple measurements and controls in one platform. It offers a highly flexible setup for students to:
– Understand and apply principles of thermal physics.
– Explore the behavior of different materials under varying thermal conditions.
– Develop problem-solving skills and critical thinking through hands-on experimentation.
This comprehensive experimental apparatus consists of a control unit and independent functional modules. The control unit integrates measurement and display units for parameters such as temperature, pressure, voltage, and current with high-precision long time timing unit, PID control and manual control unit, multiple sets of DC power supply unit, and four-way sensor interface unit. Each functional module is specifically designed for a set of particular experiments (at present, there is only one module available and more modules will be added when they become available).
Using the control unit and module # 1, the following experiments can be performed:
(1) PID applications
(2) Heat conductive coefficient measurement of a poor conductor
(3) Heat conductive coefficient measurement of air
(4) Heat conductive coefficient measurement of a metal
(5) Specific heat capacity measurement of a metal
(6) Linear expansion coefficient measurement of a metal
The LETI-40 comes with an instruction manual containing:
– Experimental Configurations: Detailed setup instructions for each experiment.
– Principles: A theoretical background to help students understand the concepts behind each experiment.
– Step-by-Step Instructions: A guide to help students conduct experiments methodically.
– Examples of Results: Sample data and analysis to help students interpret their findings and verify results.
