System Introduction

The constant temperature and humidity test chamber can provide a simulated environment for users to inspect and test electronic and electrical components, spare parts, or related industry experimental departments. The constant temperature and humidity test chamber has simple operation performance and reliable equipment performance for the accuracy and reliability of test data. The most advanced and convenient measuring device, temperature and humidity controller, adopts advanced Chinese LCD display touch screen, and can perform various complex program settings. The program settings adopt dialogue mode, and the operation is simple and fast.

It can achieve automatic operation of the refrigeration machine, maximize automation, reduce the working time of operators, and can automatically start, stop, and operate at any time. The work of each system (fan, refrigeration dehumidification, heating, humidification) is centrally controlled by the touch screen human-machine interface. The overall assembly is carried out at the customer's end, with convenient transportation and placement, and on-site debugging and acceptance are carried out at the customer's end to ensure the performance of use at the customer's end;

High degree of structural integration, short assembly and debugging time on the client side; Scientific air circulation design ensures even indoor temperature and humidity, avoiding any dead corners; A complete safety protection device avoids any potential safety hazards and ensures the long-term reliability of the equipment; Each product is customized according to customer requirements, ensuring the efficiency and energy saving of the equipment.

Reference standards

Environmental testing requirements for temperature and humidity in GB/T2423-2001 standard;

The price of the constant temperature and humidity test chamber includes heating, humidification, and dehumidification systems

1. Heating is achieved through the use of heating wires, and solid-state relays are used for the execution components; Humidifier adopts water evaporation method (external humidification), equipped with water cut-off protector, automatic water level controller, and automatic water filling device. Dehumidification adopts condensation method and is equipped with a dehumidification evaporator, which condenses the water vapor in the air inside the working room into water on the dehumidification evaporator and discharges it outside the box to reduce the relative humidity of the working room.

2. The humidity sensor adopts an imported capacitive sensor. Compared with the "dry wet bulb" method, it is more suitable for conducting long-term temperature and humidity tests because there is no need to worry about the wet bulb water replenishment system, water quality, and other issues, and there is no need to frequently replace the yarn cover.

1. Setting method: Touch, click

2. Display mode: Color LCD backlit touch screen with Chinese display

3. Setting and display resolution: temperature (0.1 ℃); Humidity (0.1% RH); Time (1 minute)

4. Graphic display: Fully display the set program curve.

5. Set parameter storage time: After fully charged, data can be saved for 5 years.

6. Number of programs: 1-499 (the largest being 499 programs).

7. Program segments: 1 to 64 segments per program; Can run by group connection.

8. It can automatically prompt users to correctly set temperature, humidity, and time parameters.

9. There is a dedicated maintenance interface for debugging and maintaining equipment with program running and maintenance functions.
