Introduction

The guard hot box is used to measure the thermal transmission properties of wall and plate insulation materials. The whole test process is automatically controlled by the microcomputer system. After the test is completed, the test report is automatically formed. It is an ideal inspection equipment for the construction quality inspection department and the energy-saving product research and development and detection organization

Features

1. The computer and instrument monitoring system (one set) adopts a two-level computer distributed monitoring system composed of computer system and temperature control expert intelligent instruments imported from Japan, which is accurate and stable in control and has a long mean time between failures; It has the functions of automatic safety protection, automatic temperature protection, over-voltage protection, over-current protection, etc. It adopts a microcomputer automatic control system, and has the advantages of fully automatic data acquisition, temperature control, curve display, result calculation, data storage, report generation, etc. in the experimental process.

2. The cold box (with built-in refrigeration unit and heating balance device) (one set) is composed of polyurethane sandwich color plates. The built-in evaporator and heating balance device can easily control the temperature at – 10 ℃ or 20 ℃.

3. Protective heat box (built-in plate and frame refrigeration unit and heating balance device) (one set) The protective heat box is composed of a heat box, a small plate and frame refrigeration unit, a heating belt, an axial flow fan, etc. The balance method of cold and hot confrontation is adopted to keep the temperature field of the protective heat box uniform and stable, and consistent with the temperature of the measuring heat box, so that the temperature difference of the test environment is minimized, and the heat loss through the measuring box is minimized.

4. The specimen frame (one set) adopts a quick locking device to clamp the specimen, so that the clamping is convenient and the clamping force is stable and consistent;

5. Electric heating and temperature, electric power measurement system (one set) uses resistance wire to form an electric heating system. Temperature measurement adopts high-precision digital temperature sensor to measure point by point, and high-precision electricity meter to measure.

6. The equipment shell of cold rail plate plus electrostatic spraying process, which is processed by advanced sheet metal production machines such as laser metal cutting machine and numerical control bending machine, is beautiful and elegant, with fine workmanship and high mechanical strength

7. Full automatic trouble free operation function, automatic diagnosis and detection function. Automatic storage, real-time recording and printing in the whole process
