The entire programmable series of machines will perform relevant processing during power on self-test alarm, and use a high fidelity platinum PT-100 temperature sensor to resist the processing of related images. The LCD is a touch sensitive/touch sensitive screen in both Chinese and English, with multiple sets of PID control functions. For curves, historical data can be selected and copied by USB according to the date. It is equipped with RS-232C/485C computer interface control, which can simulate different environmental conditions such as high temperature and high humidity/high temperature and low humidity/low temperature and high humidity/high temperature and low temperature. The software is relatively easy to use, with an IBM PC compatible machine, a PII or above CPU, and more than 128MB of memory. It is also equipped with a high-precision programming control and fixed-point control system that is easy to operate and learn, providing * testing. Function: The length of use requires a flat ground, good ventilation, and no flammable, explosive, corrosive gases or dust.

Programmable high and low temperature test chamberPrecautions during use:

Wet ball gauze: It is necessary to observe and pay attention to whether the gauze is placed correctly and whether it has been wetted. Secondly, check whether the water level in the water supply tank is normal

Humidifier water level issue: Is the water level normal/Is the humidifier water clean

Drainage pipe matters: Is the drainage pipe properly connected

Confirm power and grounding matters: Whether the power cord is properly installed according to specifications and properly grounded. The grounding wire should only be removed when the temperature is high. If the gauze is operated at a high temperature of 85 ℃ or above, it should be replaced before the next operation. Otherwise, it may not be able to absorb water again. When replacing the new gauze, wash your hands first

Confirmation of water supply: whether the water storage capacity has been communicated and whether the box cover is properly closed
