Scope of use:
Use scientific methods to create a long-term temperature and humidity environment required for product or material failure evaluation.
Suitable for storage, transportation, and storage of electrical, electronic products, and other original components and materials in high and low temperature environments.
Suitability test during use.
Features:
Humanized design
1. Brand new fluorine-free design.
2. Original imported special digital display temperature and humidity controller, with clear and intuitive display, stable control and easy operation.
3. Imported high-precision wet-bulb or capacitive humidity sensor with high sensitivity and small drift.
Quality Assurance
1. International brand compressor and circulation fan ensure uniform temperature and humidity distribution.
2. Environmentally friendly refrigerants are highly efficient, have low energy consumption, and promote energy saving.
3. Unique air duct system ensures uniform temperature and humidity in the working room.
4. Adopt SU304 stainless steel inner tank, semicircular arc transition at four corners, partition bracket can be freely loaded and unloaded for easy cleaning.
safety devices
1. Independent temperature limit alarm system, when the temperature exceeds the limit, the operation will be automatically interrupted and the operator will be alerted by sound and light. Ensure the safe operation of the test without accidents
2. Compressor overheat, overcurrent, overpressure, overload protection, fan overheat, overcurrent protection, etc.
Optional equipment
1. RS485 interface can control multiple or single instruments through computer and record and backup control data in real time.
2. Paperless recorder and SMS alarm.
