This article is the definition for 3 drawers steam aging test chamber which comes from a China manufacturer. This type steam aging test chamber mainly used for cable wire test, PCB board solderability test, or any other small SMD capacitors etc. We appreciate the Chezh Republic customer ordered the steam aging test chamber from Wewon Environmental Chambers Co., Ltd.
Today, We have taken some photos before packing and send to customer for checking purpose. There has 3 units steam aging test machine which has been finished the testing work by Wewon quality control dept. So if we will receive another 2 units orders of steam aging test chamber, Then We can prepare the packing work and ship to customer quickly !

1 | Please set the working mode, delay range and delay time before working the time relay. The change after power on is invalid, and it shall be reset. | DIRECTIONS FOR USE |
2 | The time of two power outages should not be less than 1 second. If the interval is relatively short, it is recommended to use the reset terminal to reset, and the reset time is greater than 0.02 seconds. | |
3 | Do not connect weak wires with other strong wires or entangle them. | |
4 | It is recommended to use the twisted pair in the power cord in the environment of strong interference. | |
5 | Do not use in dusty, corrosive gas, direct sunlight, rain. | |
6 | Please store and use under rated voltage, specified temperature and humidity. |
