Temperature and Humidity Chamber
IEC 60068 Steam Aging Test Chamber
TT-SATC steam aging test chamber for IEC 60068 steam aging tests: three SUS304 sample drawers, steam temperature from room temperature +5 °C to 98 °C at ≥95 % RH, PID control with PT100 sensor, timer from 1 s to 9999 h, and over-temperature, leakage and water-shortage protections.
Overview
The TT-SATC steam aging test chamber performs steam aging tests on electronic components under a sealed steam atmosphere near 98 °C at a relative humidity of 95 % or higher. The accelerated moist-heat exposure evaluates the moisture resistance of connector plating, IC packages, transistors, diodes, resistances and other passive components, and helps predict how finishes and seals behave over long service life in humid environments.
Key Features
The working space holds three stainless steel sample drawers (85 × 300 × 50 mm each) with bakelite handles, so batches of small parts can be loaded and removed quickly. Both the inner and outer chamber are made of SUS 304 stainless steel, heated by a titanium heating tube, and insulated with PU and fiberglass wool to keep the outer shell cool.
A PID controller with a PT100 sensor and SSR output keeps the steam temperature from room temperature +5 °C to 98 °C within ±1 °C fluctuation. The timer covers 1 s to 9999 h, water can be filled manually or replenished automatically from a tap-water connection, and operation resumes automatically after a power failure. Over-temperature, electrical leakage and water-shortage protections are built in, with run and fault indicators on the panel.

Applications
Steam aging is commonly requested for connector and electronic-component quality control, and the TT-SATC is frequently ordered together with our ozone aging test chamber for rubber and ASTM xenon arc weathering test chamber to cover accelerated aging projects from one laboratory.
Typical samples include connectors, ICs, transistors, LCD modules, diodes and resistances that need their plating and sealing evaluated before shipment.
