1. Material code

WHW-200L-0C-220V-5V100mA-160CH

2. Product application

Constant temperature testing is conducted for button cells, pouch cells, and cylindrical batteries.

Electronics, electrical equipment, instrumentation, materials, semiconductor manufacturers, and other industrial producers perform thermal stability tests on non-flammable, non-explosive materials.

Environmental protection agencies, agricultural/livestock/aquatic research institutions, and production facilities utilize controlled temperature environments for water quality analysis, bacterial/microbial culture preservation, as well as plant cultivation and breeding experiments.

3. Sample restriction

This testing equipment strictly prohibits:

The testing or storage of any samples containing flammable, explosive, or volatile substances; corrosive materials; strong electromagnetic emission sources; radioactive substances; highly toxic materials; as well as any samples that may generate such hazardous substances or objects during testing or storage procedures.
