Structure and Characteristics
1. This testing instrument mainly consists of three parts: a constant temperature bath, a gas supply system, and a control box. A precision flow meter and gas supply connector imported from Japan are installed above the constant temperature bath, and an electrical control box is located at the top. The constant temperature bath body is made of imported stainless steel material.
2. Heating and stirring device: The two heating and stirring heads of this tester are installed together on a flat plate. During maintenance, simply remove the fixing screws of the plate to easily remove it from the constant temperature bath.
3. Accurate and stable flow control: The continuous working time of the transformer oil oxidation stability tester is up to 164 hours, and its oxidation flow control accuracy is required to be very high. During this period, there are also changes in day and night temperatures. Therefore, the control accuracy and stability of the flow rate are the key to this tester. The stabilizing device designed by our company ensures stability during initial pressure or environmental temperature changes, while the imported precision flowmeter and precision needle valve ensure its testing accuracy.
4. Microcomputer control has:
a) Accurate temperature control; The temperature fluctuation and uniformity can reach ± 0.1 ℃;
b) Automatic shutdown protection function for power and gas outages;
c) Automatic shutdown and reporting at the end of the experiment;
d) Self diagnostic function: Sensor fault alarm; Heater open circuit alarm; Pressure loss alarm;
e) Automatic timing function: It automatically accumulates the actual test time and memorizes the start date of the test, and can also query the time and date of the test interruption caused by gas or power failure.
f) Rich display content: display of set temperature and actual temperature; Display the start and end dates of the experiment; Display of interruption test date and time; Fault display;

Due to its modular design, it can be adjusted according to ASTM D943、ASTM D2274、ASTM D4310、ASTM D7462、ISO 12205、ISO 4263-1、ISO 4263-2、ISO 4263-3、JIS C 2101、JIS K 2514 Customize your instrument with ease according to standards.
