SYD 265-1 capillary cleaning
This instrument is a device for measuring the viscosity of the oil equipment. It is mainly used for measuring the viscosity of oil in a capillary viscometer key attachments (or other similar devices) cleaning, viscosity measurements can also be used in the initial phase of sampling of the specimen.
Instructions:
Very convenient to use the instrument, press the view of the connector, Port A Port A hose coupling capillary viscometer, the capillary viscometer (or other similar items to be washed) C port immersed in the bath and block B port. When cleaning large diameter viscometer, the movable switch using the instrument on the left point to control the pump intermittent work, and vice versa when cleaning small diameter viscometer, the instrument on the right to open the switch, so that the pump for continuous operation. When the waste liquid is visible in the instrument window, you should immediately turn off the switch, will be decanted waste bottle, if necessary washed again, repeat the above operation until the cleaning requirements.
Precautions:
Throughout the cleaning process, should pay close attention to the waste liquid bottle height to avoid contact with the waste liquid is sucked by the pump inlet and outlet tubes, so that damage to the instrument.TAG：
SYD-508 Petroleum Products Ash Tester
Purpose:
This instrument is in accordance with the national standard GB / T 508-85 requirements “Petroleum products – Determination of ash,” the manufacture, applicable to the determination of ash content of petroleum products, but not containing raw ash additives (additives including certain phosphorus-containing compounds) of petroleum products, nor to lead lubricating oil and used engine crankcase oil.
Technical Parameters:
1. Power: 220V 50Hz AC
2. Total power: 4.9kW
3. The use of ambient temperature: 10 ~ 40 ℃
Summary of Method:
Ash-free filter paper for core fire ignited in the appropriate sample crucible, and burned to ash and leaving residual carbon. And then heating the carbonaceous residue is converted to ash at points 775 ℃ high temperature furnace, then cooled and weighed
