This apparatus uses a diffused Silicon pressure sensor to measure gas pressure and uses an integrated temperature sensor to measure temperature, achieving higher accuracy and sensitivity on the measurement of gas pressure and temperature. Experiment error is less than 3%.
This apparatus takes copper as the standard sample and measures the specific heat capacity of iron and aluminum samples at 100 °C under conditions of forced convective cooling and natural cooling.
This apparatus measures the air density and universal gas constant using vacuuming method. It has the features of small size, convenient operation and durable structure. Experimental data are stable and reliable.
This experiment measures the thermal conductivity coefficient of a poor conductor (rubber) by using steady-state method. Students will master the experimental method for calculating the transfer rate and cooling rate.
This apparatus utilizes a Michelson interferometer to determine the linear expansion coefficient of sample material. The accuracy of length expansion of a heated sample is better than submicron.
This comprehensive experimental apparatus consists of a control unit and a number of functional modules. The control unit integrates measurement and display units while each functional module is specifically designed for a particular experiment.
This apparatus consists of a precise temperature control system, a constant-current source, a DC bridge, DC power supplies and a digital voltmeter. It is used to study the temperature properties of various temperature sensors.
Experiments include the measurement of temperature properties of different temperature sensors and their applications on measuring human body temperature at different body parts.
