PRRH 309heat treatment oil thermal oxidation stability analyzer
The heat treatment oil thermal oxidation stability analyzer is produced by the introduction of advanced technology from Japan to line SH/T0219 standard. Pass into the air, in the presence of iron and copper catalysts, the measurement test in a kinematic viscosity in the oxidation and carbon residue. Instrument adopts imported stainless steel the frosted plates, designed beautifully durable anti-corrosion. Fuzzy control principles and PID self-tuning technology, stable and reliable control performance. Modular maintenance-free technology, compact, long life. As a high-precision thermostatic bath is widely applicable to a variety of tests, preferred laboratory test equipment.
The instrument uses fuzzy control theory, expert PID self-tuning technology, and the modular maintenance-free structure, reliable control performance, users only need to set the temperature of the temperature control point through the instrument, the instrument automatically designated temperature control. The structural characteristics of the instrument using imported stainless steel frosted plate, handsome in appearance, anti-corrosion and durable. Composed of the superstructure part bathtub and control operation part. This instrument has the following characteristics: a compact structure, beautiful shape, easy to operate. Second, the stirring shaft, pulp, bath, and a housing made ??of stainless steel. Third, the end of the trial can sound and light tips signals, to remind laboratory technicians to the end of the test.
