HZ2831 ASTM D1275 Electrical Insulating Oil Corrosive Sulfur Tester

I.Scope of application：

This product is manufactured in accordance with SH/T0304 ASTM D1275 electrical insulating oil corrosive sulfur test method and is suitable for the determination of corrosive sulfur in electrical insulating oil extracted from petroleum.

II.Technical index：

III.Structure overview:

1. This instrument adopts imported digital display PID program temperature control, and adopts special non-overshoot PID algorithm and PID self-tuning technology to ensure that the instrument does not overshoot or undershoot, and the temperature control accuracy can reach ±0.5℃.

2. The temperature measurement is carried out by Pt100 sensor. The sensor is sensitive, reliable in work, and can quickly and timely reflect temperature changes. Through the control of the digital display PID thermostat, it can fully guarantee the temperature control accuracy required by the standard.

3. The appearance of this instrument adopts an integral frame structure with large internal space. The shell is made of high-quality cold-rolled steel plate, and the surface is treated by spraying process, with a novel and beautiful appearance.

4. The inner tank is made of stainless steel plate through anti-corrosion treatment and processing.

5. There is a double-glazed observation window in the middle of the door, which can observe the heated objects in the working room at any time.

6. The door of the box is inlaid with high temperature resistant rubber strips, which has good airtightness and prevents heat loss.

7. An exhaust valve is set on the upper side of the working room, and the moisture released by the heater can be discharged out of the box at any time during the working process.

8. The temperature in the box is forced to circulate by a fan to ensure that the temperature uniformity is controlled within ±2.5%.
