This paper introduces a kind of metal bath test chamber for the test glue/paint materials under the set temperature environment to maintain temperature, the test chamber adopts the heating rods for custom aluminum heating, which can realize automatic temperature control inthe temperature range (50~220℃). This metal bath test chamber has four test chambers with Φ80 ×260 mm, temperature uniformity in the chamber is not more than plus or minus 2℃, volatility is not more than 0.2℃. Two holes on the Furnace top can realize the furnace body temperature real-time monitoring.The metal bath test chamber with small volatility, uniform heating, is very suitable for high temperature oil resistant test of the rubber sealing material.
