HH-WL-508 is specially designed for thermostat durability testing. It supports 10-station parallel aging test (single-station independent counting), covers -25℃~85℃ temperature cycle (accuracy ±1℃) and 1-10 times/minute high-frequency start and stop, and integrates dry-burn protection trigger response (≤5s), action life (1 million times), temperature difference accuracy (±0.5℃) full-item testing. Equipped with intelligent pneumatic clamping system and automatic fault diagnosis function, it complies with GB 14536.1 and IEC 60730 international standards, automatically generates aging curves and qualified judgment reports, and is the core testing equipment for home appliance manufacturers, thermostat manufacturers and quality inspection agencies.
