I assume that most of you are no strangers to Linpin's high and low temperature alternating humidity-heat test chamber. While gaining a deep understanding of its application scenarios and operational methods, we must never overlook its maintenance essentials.

To ensure the electrical, mechanical and thermodynamic integrity of constant temperature and humidity test chambers (hereafter “the chamber”), to standardize operating procedures, and to reduce failure and accident rates, this instruction is established. It applies to all programmable, single-point and walk-in chambers that are newly purchased, in service or relocated.

There are many manufacturers of rain test chamber equipment on the market, and customers can choose the appropriate equipment based on their testing needs.

Dust testing, codified in GB/T 2423.37 and IEC 60068-2-68, is now mandatory for proving the sealing integrity and reliability of military, automotive, photovoltaic and rail-transit products. Direct test outlays—consumables, energy, labour and depreciation—seldom exceed one to three per cent of the selling price, yet hidden expenses triggered by poor chamber selection—repeat tests, invalid data or after-sales downtime—can leap to eight to twelve per cent.

A low-temperature test chamber can accommodate multiple test specimens, but are there specific requirements regarding the location and quantity of test points? Today, we will introduce the guidelines for test point placement and quantity in such equipment.
