Oil Damp Heat

The oil humidity-heat test simulates high-temperature and high-humidity environments to evaluate the oxidation, corrosion, and performance changes of oil products under such conditions. By controlling temperature and humidity in a constant temperature and humidity chamber, changes in indicators such as the appearance and acid value of oil samples are observed. This test is used to assess the storage stability and anti-aging capabilities of industrial oils such as lubricants and hydraulic oils.
Selection
When selecting an oil humidity and heat testing instrument, consider the precision of temperature and humidity control. Common conditions are 40℃ and 93% humidity. The chamber material should be corrosion-resistant, and the volume should be determined based on the number of samples. Ensure compliance with standards such as GB/T 2361, with a user-friendly operation interface and data recording capabilities. Choose an appropriate size according to laboratory space, and ensure moderate maintenance costs.
