PRRH0175 automatic diesel oxidation stability tester

Executive standard: designed and manufactured according to SH/T0175 Test Method for Oxidation Stability of Distillate Fuel Oil (Accelerated Method).

Scope of application: applicable to the determination of inherent stability of intermediate distillate fuel oil under accelerated oxidation conditions. Method summary: The filtered 350ml sample was subjected to continuous bubbling with oxygen and aging at 95 ℃ for 16 hours. After the aging and cooling, the total insoluble content of the sample was measured, expressed in mg/100ml.

Performance characteristics: the instrument is composed of heated water bath, cooling chamber and control system. All stainless steel construction, corrosion resistant. Single-chip microcomputer control system controls the whole process to achieve "guard free" status. Automatic water level protection system to ensure the water level in the experiment. It can automatically complete the injection, constant temperature, cooling, oxidation process, alarm, whole-process monitoring and other work. The operator can work in the operation mode of "start - no guard" to complete the whole process of oxidation - cooling specified in the standard. It has fault diagnosis function. Once a fault occurs, it will automatically alarm and the instrument will automatically take safety protection measures. Its functions include thermostatic bath over-temperature protection, thermostatic bath water level protection, heater protection, etc., providing reliable guarantee for safe operation of the instrument. This instrument is characterized by unique design, high degree of automation and easy operation.
