Overview

The Hebei high and low temperature alternating humidity chamber is mainly used to conduct environmental simulation tests on the physical and other related characteristics of products under high and low temperature conditions according to standard requirements or user defined requirements. After testing, the performance of the product can still meet the predetermined requirements through testing, in order to facilitate product design, improvement, identification, and factory inspection.

Product Details

Hebei high and low temperature alternating humidity chamberPerformance parameters:

The Balanced Temperature Control System (BTHC)+specially designed fan forced circulation system controls SSR in a P.I.D. manner, ensuring that the heating amount of the system is equal to the heat loss, thus enabling stable use.

The performance measured after being stable for 2 hours without test load or scaffolding. In addition, the temperature rise and fall time refers to the air-cooled type at room temperature+25 ℃ when unloaded.

Model Explanation		GDWJ-80F refers to a high and low temperature test chamber with a temperature range of -40 ℃ -150 ℃ and an internal volume of 80 liters. GDWJ -- represents high and low temperature test chamber 80- represents internal volume F - represents temperature range (Z represents low temperature 0 ℃, T represents low temperature -20 ℃, F represents low temperature -40 ℃, S represents low temperature -60 ℃, SS represents low temperature -70 ℃) Note: The internal and external dimensions of the test chamber may be adjusted according to the selected appearance, and the actual dimensions will be determined through communication with the manufacturer

Controller: Adopting fully imported LED digital display LCD touch screen with Chinese English switching interface programmable controller;

After inputting the data and experimental conditions, the controller has a locking function, which can prevent human touch from changing the temperature value;

The controller has PID automatic calculation function, which can immediately correct the temperature change conditions, making temperature control more accurate and stable;

Optional printer, capable of printing and recording set parameters, scanning temperature and humidity change curves, and 4-20mA standard signals;

Structural characteristics of high and low temperature test chamber:

The box is processed and formed by CNC machine tools, with a beautiful and elegant shape, and adopts non reactive handles for easy operation;

The inner lining of the box is made of imported high-grade stainless steel (SUS304) mirror panel, and the outer lining of the box is made of (SUS304) brushed stainless steel or high-quality cold-rolled steel plate spray painted, which increases the appearance texture and cleanliness.

The insulation material is made of high-density glass fiber cotton with a thickness of 80-100mm. A double-layer high-temperature resistant high tensile sealing strip is used between the door and the box to ensure the sealing of the testing area.

The left side of the box is equipped with a diameter (25mm, 50mm, 100mm optional) test hole, which can be used for external testing power or signal lines.

There is a large observation window with lighting to keep the inside of the test chamber bright, and it is conducive to embedding tempered glass inside the heating body, allowing clear observation of the condition inside the test chamber at any time.

Equipped with an independent temperature limit alarm system, exceeding the limit temperature and automatically interrupting operation ensures safe testing without accidents.

The water replenishment tank is located at the bottom of the control box and has automatic water shortage protection, making it more convenient for operators to replenish water sources. (Referring to the damp heat test chamber)

Hebei high and low temperature alternating humidity chamberOperating system:

The refrigeration unit adopts a fully enclosed French Taikang (or semi enclosed German Gulun) compressor.

The refrigeration system adopts a unit or binary low-temperature circuit system design.

Adopting air-cooled single-stage compressor or air-cooled cascade compression refrigeration method.

Adopting a multi wing centrifugal fan powerful air circulation system, avoiding any dead corners, can make the temperature and humidity distribution in the testing area uniform.

The design of air circulation for air outlet and return meets the testing standards for wind pressure and speed, and can quickly stabilize the temperature and humidity at the moment of opening the door.

Adjust the air guide plate up, down, left, and right to ensure even distribution of temperature and humidity.

Compliance and fulfillment of standards: The performance indicators meet the technical conditions of the GB10592-89 high and low temperature test chamber, which is suitable for conducting low temperature, high temperature tests and constant temperature tests on products in accordance with GB2423.1 and GB2423.2 "Environmental Testing of Electrical and Electronic Products - Test A: Low Temperature Test Method, Test B: High Temperature Test Method". The product complies with GB2423.1, GB2423.2, GJB150.3, GJB150.4, IEC, and MIL standards.
