HE leak detection machine has dual functions of leak detection and real water detection. It can accurately locate the leak point of defective products and simulate underwater stress to verify the waterproof performance of the product.The equipment uses digital display pressure and timing with an accuracy of 0.2% F.S. The fully transparent cylinder is easy to observe.The rotary adjustment and lever switch prevent accidental touch, and the anti-fool andover-voltage protection functions ensure safety and reliability.It effectively improves maintenance efficiency and reduces waterproof verification costs. It is an efficient choice for air tightness testing and waterproof verification.
