Overview
JINGHONG GDH-2050A low/high temperature test Chamber is a equipment for high and low temperature or heat and humidity environmental testing and testing in industrial and mining enterprises, laboratories, R & D institutions, etc. Its Inner Chamber dimensions are 700 * 800 * 890mm, Temperature range is -20~ 100 ℃, with precise temperature control and comprehensive Safety protection functions.
Features
1, the use of 304 stainless steel liner, surrounded by semi-circular arc easy to clean, adjustable shelf spacing.
2. Adopt French "Taikang" fully enclosed Compressor, stable and reliable operation.
3. Microcomputer temperature controller, with dual digital display for setting and measuring temperature and PID self-tuning function, accurate and reliable temperature control.
4. The air duct circulation system is composed of low-noise German imported fans and suitable air ducts, with uniform indoor temperature.
5. The refrigeration system uses environmentally friendly working fluids to effectively reduce energy consumption and promote energy conservation and emission reduction.
6. There is a 25mm diameter test hole on the left side of the box, which can be used for external test power and signal wires.
7, over-temperature alarm system, sound and light alarm prompts the operator to ensure the safe operation of the experiment without accident.
8. Comprehensive safety device protection has protective functions for Compressor overheating, fan overheating, Compressor overpressure, phase loss, overload, overtemperature, humidifier water shortage, humidifier dry burning, etc.
9. Embedded printer (optional), which can print and record the temperature at different times, making it convenient to check the temperature control of the whole process.
Principle
The equipment sets the target temperature through the microcomputer temperature controller, controls the refrigeration system (using the French Taikang fully enclosed Compressor) and the heating system to work, and realizes the temperature rise and fall in the box. The air duct circulation system (driven by the German imported fan) ensures the Temperature uniformity in the working room. The equipment monitors the temperature in real time through the PT100 Platinum Resistance Sensor, and uses the PID self-tuning function to achieve accurate temperature control.
Applications
Industrial and mining enterprises, laboratories, R & D institutions
Standards
GB/T2423.1-2001、GB/T2423.2-2001、GB/T2423.3-1993、GB/T2423.4-1993、GB-10592-89
Steps
1. Connect the device power supply (380V/50HZ).
2. Set the required test temperature through a microcomputer temperature controller.
3. Adjust the shelf spacing and place samples as needed.
4. You can use the test hole on the left side of the box to connect the external test line.
5. Start the equipment and start the test.
6. During the test, the real-time temperature can be observed through the controller, and the optional printer can record the temperature data.
7. After the test is completed, turn off the power supply of the equipment.
Notice
Equipment should operate at Ambient Temperature 15~ 30 ℃.
Power supply voltage requirement is 380V/50HZ.
Please confirm the water volume of the humidifier before use to avoid dry burning.
When the equipment is running, please pay attention to alarm prompts such as overtemperature to ensure safety.
Before performing maintenance or cleaning, be sure to disconnect the power supply of the equipment.
The optional embedded printer is a non-standard function and can be purchased on demand.
