Overview
Programmable constant temperature and humidity testing machine NBC-1000L-40 is mainly used to detect the performance of materials in various environments, test the heat resistance, cold resistance, dry resistance and moisture resistance performance of various materials. Suitable for mass detection of electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metals, food, chemicals, building materials, aerospace and other products. Using equilibrate Conditioning Control System (BTHC), the actual data in the test chamber is transmitted to the controller through the induction system, and the controller controls the SSR to realize multi-stage intelligent output. The output power of the equilibrate temperature and humidity system ensures that the temperature and humidity in the test chamber are fully stable, and has the function of energy saving, reducing the power of the instrument, and ensuring long-term accurate and stable operation.

The instrument has a comprehensive protection system, including power overload protection, leakage protection, control loop overload, short circuit protection, Compressor protection, grounding protection, over-temperature protection, alarm sound prompt, and automatically display the fault point and stop when abnormal.
Principle
The equilibrate Conditioning control system (BTHC) is adopted, and the induction system transmits the actual data in the test chamber to the controller. The controller realizes multi-stage intelligent output by controlling the SSR, and the output power of the equilibrate temperature and humidity system ensures that the temperature and humidity in the test chamber are fully stable. The heating system adopts multi-stage heating pipes with PID modules to ensure stable temperature and energy saving; the humidification system adopts a circular split humidifier to avoid low temperature freezing, and the humidification pipe can be dry burned for more than 1 hour; the refrigeration system adopts imported Compressors, condensers, evaporators and other components, and cooperates with energy-saving regulating valves to realize forced refrigeration and thermostatic refrigeration segmented control; the air circulation system adopts high-resistance motors and multi-wing fan blades to ensure uniform air circulation.
Applications
Electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metals, food, chemicals, building materials, aerospace
Steps
1. Set the temperature and humidity program through the controller Linear dispersion.
2. Use the RS232 computer interface for remote control (optional).
3. Adjust the shelf spacing or remove the shelf to place the sample.
4. Start the instrument for testing and monitor the operating status of the system.
5. After the test is completed, the instrument automatically stops and displays the results.
Notice
• The use environment temperature should be between 0~ 30 ℃, and the performance guarantee environment is 5~ 25 ℃.
• Miscellaneous items cannot be placed within 60CM of the instrument.
• Note that the Power supply voltage is 380V/50HZ, and the allowable voltage variation is +/- 10%.
• The humidification system has water filtrating and requires regular maintenance to avoid clogging.
• The instrument has a comprehensive protection system, which automatically stops when abnormal, and needs to check the fault point in time.
• Use the bottom universal wheel when moving the instrument, pay attention to load bearing and shock absorption.
