Thermal Conductivity Measurement Apparatus Experiments

Digital Voltmeter :

• 3.5-digit display, measuring range 0–20 mV, accuracy ±(0.1% + 2 digits).

Digital Stopwatch :

• Five-digit timer with a minimum resolution of 0.01 seconds.

Temperature Controller Range :

• Ambient temperature to 120°C.

Heating Supply :

• AC 36 V (high setting) and AC 25 V (low setting), with approximately 100 W heating power.

Heat Dissipation Copper Plate :

• Radius 65 mm, thickness 7 mm, mass 810 g.

Test Materials :

• Duralumin, silicone rubber, rubber sheet, air, and other thermal conductivity samples.

Thermocouple Compensation :

• Optional cold-junction compensation circuit eliminates the need for an ice-water reference mixture.

Sensor Compatibility :

• Supports additional temperature sensors including PT100, AD590, and similar devices.

Designed For :

• Physics Lab Experiments from Atico Exports.

• Isolated low-voltage heating system ensures safe and convenient operation during laboratory experiments.

• Standard thermocouple with flexible Teflon protective tubing minimizes the risk of thermocouple damage.

• Thermoelectric potential measurement through a high-input-resistance, high-precision, low-drift amplifier combined with a 3.5-digit digital voltmeter.

• PID temperature control system maintains stable heating plate temperature, improving experimental accuracy and repeatability.
