DKGD series high and low temperature environmental test chamber

　DKGD series high and low temperature environmental test chamber（-70～+350℃）

◆Overview

This device can be used for material mechanics testing such as tensile, compressive, bending, and shear testing of metal and non-metal materials in high and low temperature environments. Can be configured on electronic universal testing machines and electro-hydraulic servo universal testing machines. Can meet the national standardGB/T228.2-2015High temperature tensile test method for metallic materials GB/T0592The technical requirements of the "Technical Conditions for High and Low Temperature Test Chambers".

◆ Structure and test configuration

1. Low temperature is cooled by a compressor; Thermal compensation adopts resistance wireOr high-temperature alloy tubeHeating method.

2. The box is made of stainless steel plate, with a front door and an observation window. There is lighting inside the box for easy observation during the testing process.

3. On demand configuration on the testing machine, used for tensile, compressive, bending, shear and other tests.

4. The temperature controller adopts a high-precision PID regulator with a display sensitivity of 0.1 ℃; Accurate temperature control.

5. Equipped with a mobile track arm car system, it can be easily transferred and operated in and out of the testing machine space.

6. Equipped withdrumThe wind circulation system ensures that the temperature gradient and fluctuation inside the furnace meet the relevant standard requirements.

7. Safety devices: Fan overload protection, compressor overpressure, overcurrent protection, phase sequence protection, circuit breaker protection functions.
