Domestic manufacturer of constant humidity and temperature test chamber

Tire constant temperature and humidity test chamber, affordable price, high temperature and high humidity testing machine

Humidity Chamber

The constant temperature and humidity test chamber is divided into two box and three box types, with the difference being the internal structure of the equipment and the testing method. The equipment is mainly used to test the material structure or composite materials, and the degree to which they can withstand continuous environments at high and extremely low temperatures in an instant. It can detect chemical changes or physical damage caused by thermal expansion and contraction of the sample in a short period of time.

Introduction to constant temperature and humidity test chamber:

Structure of constant temperature and humidity test box body

1. Outer wall material of the box: steel plate sprayed with plastic on the outer surface;

2. Inner wall material of the box: SUS304 stainless steel plate;

3. Observation window: Install a rectangular multi-layer insulated glass observation window (300 × 200mm) in the high-temperature box Install lighting fixtures on the observation window;

4. Thermal insulation material: polyurethane foam connects the inner chamber, shell, high-temperature chamber and low-temperature chamber into a whole through high-temperature and high-pressure foaming;

5. Sample rack load-bearing capacity: not exceeding 20 kilograms;

6. Sample rack movement method: The sample rack relies on a linear reciprocating drive system installed at the bottom of the box to move up and down;

Measurement and Control System for Constant Temperature and Humidity Test Chamber

1. Control device: The main controller adopts the Korean imported "TEMI8226" dual circuit high-precision LCD display touch button temperature controller, programmable microcomputer PID control SSR output operation, large LCD color touch screen image, simple screen operation, and easy program editing;

2. Accuracy: 0.1 ℃ (display range);

3. Resolution: ± 0.1 ℃;

4. Refrigeration system and compressor: In order to ensure the cooling rate and low temperature requirements of the test chamber, this test chamber adopts a binary cascade air-cooled refrigeration system composed of an imported German semi closed compressor. The cascade refrigeration system consists of a high-temperature refrigeration cycle and a low-temperature refrigeration cycle, with the connecting container being an evaporative condenser. The evaporative condenser also plays a role in energy transfer, transferring the thermal energy inside the working chamber through a two-stage refrigeration system to achieve the goal of high temperature. The design of refrigeration systems applies energy regulation technology, which is an effective processing method that can ensure the normal operation of refrigeration units while effectively adjusting the energy consumption and cooling capacity of the refrigeration system, reducing the operating costs and failure rates of the refrigeration system to a more economical state;

5. Air conditioning method: Forced ventilation internal balance temperature control method (BTC). This method refers to the control system controlling the output of the heater based on the set temperature point through PID automatic calculation output under continuous operation of the refrigeration system, ultimately achieving a dynamic balance.

The constant temperature and humidity test chamber meets the standards of GB/T2423.1.2, GB/T10592-2008, GJB150.3.
