Sand dust test chamber YSCX-100~010
The sand and dust test box is suitable for electrical and electronic products, automobiles and motorcycles spare parts 、 Sealing element Test to prevent sand dust from entering seals and housings in a sand dust environment.
To inspect the use, storage and transportation performance of electronic and electrical products, automobile, motorcycle parts and seals in the sand and dust environment.
structure characteristics
The shell of sand dust test chamber is cold rolled steel plate Electrostatic spray molding, the inner liner is made of high-quality stainless steel plate, and the overall appearance is beautiful and generous. box door Large area observation in the middle window Add manual wiper
The sand dust test chamber can easily see the test condition of the test piece during the test. The main controller of the equipment adopts the intelligent digital display controller, and the main controller of the sand dust test box adopts the
Intelligent digital display temperature controller, user-friendly design of the operation method, easy to learn and use, and different functional levels of instrument operation are mutually compatible. Digital correction system is adopted for input, with built-in constant
Use thermocouple and thermal resistance non-linear correction table to measure accurately and stably. The sand and dust test chamber has position adjustment and AI artificial intelligence adjustment functions, 0.2 level accuracy, and multiple startup emergency signal modes.
The equipment has timing function. Stainless steel fin heating tube is used for equipment heating. The dust blowing cycle and vibration cycle of the whole equipment can be adjusted, and the timer for the total test is equipped.
