DP3115B Air Leakage Tester

DP3115B series is an air tightness tester developed specifically for the new energy vehicle industry. It adopts a mature multi-channel differential pressure design, which is far less susceptible to temperature fluctuation and other external environmental interference.

This design delivers outstanding high test accuracy and excellent long-term stability even in busy factory workshop conditions. Equipped with an intuitive color touchscreen, it supports flexible parameter configuration, full test data storage and programmable test pressure settings. It also comes with standard PC and PLC communication interfaces for seamless connection to factory control systems and host computers.

DP3115B is a differential pressure air tightness tester used for air tightness inspection of various machined components and finished assemblies. It greatly enhances leak detection ability and helps manufacturers realize full automation of the production inspection station. This instrument is fitted with a high-sensitivity differential pressure sensor and thermally resistant pneumatic valves. Automatic self-checks for pneumatic valve operation and sensor sensitivity are executed in every single test cycle to prevent equipment drift and unreliable readings.

Its built-in self-test circuit provides excellent functional protection and operational safety. With standard error correction and error reduction functions, the system effectively shortens the overall test cycle and improves throughput. Suitable for a wide variety of test products, it can accurately display real-time test pressure, differential pressure and leakage rate directly on the touchscreen.

The DP3115B air leakage tester supports stable differential pressure measurement under repeated continuous production cycles. It features flexible multi-channel configuration, reliable data recording and standard industrial communication interfaces to integrate seamlessly into automated EOL test stations. Built strictly for mass production quality control, it quickly identifies tiny leaks for EV and energy storage components. By catching micro leaks at the end of production, it helps manufacturers reduce defective product outflow, lower after-sales risk and maintain consistent product quality in high-volume manufacturing lines.

The DP3115B Air Leakage Tester stands out among differential pressure leak testers due to its stable performance in high-cycle production environments. It is widely adopted by EV component manufacturers to conduct reliable air tightness inspection for mass quality control.
