What is ingress protection testing? Ingress Protection Testing is a standardized method used to evaluate the ability of a device or product enclosure to resist the ingress of solid particles (such as dust) and liquids (such as water). By simulating various environmental conditions, IP testing determines whether a product can prevent the entry of dust, sand, water droplets, or immersion during real-world use, ensuring the safety and reliability of electronics, machinery, and other products.

Main Categories / Test Types:

• Protection Against Solids

• Protection Against Liquids

DHT® IP Test Chambers are engineered for comprehensive ingress protection testing, offering full IP rating coverage, military-grade structural reliability, and a user-friendly intelligent interface. The DHSD Series Sand and Dust Test Chambers feature a modular design for easy installation and long-term operational stability. With precise control over dust concentration, they are specifically designed to meet IP5X/IP6X dust protection standards as well as high-speed sand and dust testing requirements in accordance with GJB 150.12A-2009. A large observation window allows for continuous visual monitoring during testing.
The DHSR Series Rain Test Chambers leverage patented spiral nozzle technology to perform IPX3 to IPX9K waterproof testing, with adjustable water pressure ranging from 0 to 300 kPa. Constructed with a 304 stainless steel inner chamber and double-layered tempered glass viewing windows, these chambers offer superior corrosion resistance and visibility.
All DHT® IP test systems are equipped with the DHSPLCON™ intelligent control platform, enabling intuitive operation via a color touchscreen, remote monitoring, and seamless data export. Built-in safety mechanisms—including leakage, short-circuit, and over-temperature protection—ensure secure, unattended operation.
