Environmental test

High temperature: put the product in(60±2)℃ for 168h, then back to normal temperature for 2h. After that, water level change of each gear is within ±15mm

Low temperature: put the product in (-20℃±2℃)for 168h, then back to normal temperature for 2h. After that, water level change of each gear is within ±10mm

Humidity resistance: Put the product in (40℃±2℃, RH90%~95%)for 168h, then dry all water from the product, back to normal temperature for 2h. After that, water level change of each gear is within ±15mm    

Durability test

With rated voltage, alternatively test the highest water level and lowest water level, frequency 20 cycles/min, total 50,000 cycles.

Environment friendly

Conform to RoHS 2011/65/EU
