Chongqing Gold Mechanical & Electrical Equipment Co.,Ltd products

This instrument is designed and made as per GB/T3536-2008 Petroleum Products - Determination of Flash and Fire Points - Cleveland open cup method and ASTM D 92 Standard Test Method for Flash and Fire Points by Cleveland Open Cup Tester. It is applicable to all petroleum products with flash points above 79℃ and below 400℃ except fuel oils.

This instrument is designed and made as per GB/T 5208-2008 Determination of flash point - Rapid equilibrium closed cup method. It can meet the requirements of rapid determination for closed cup flash point of petroleum products in oil,chemical, varnish, paint, railway, aviation, electricity, commercial inspection and science research institution. This instrument is specially suitable to determine different kinds of colored paints,oil paints, adhesives,solvents and petroleum products which the closed cup flash point is -30℃～50℃.The instrument is also correspond with ISO1523 and ISO3679.

The instrument is made as per T0622 Asphalt Engler Viscosity Test (Engler Viscometer Method) in the industrial standard of People’s Republic of China JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering, the national standard of People’s Republic of China GB/T 266 Test Methods for Engler Viscosity of Petroleum Products and the enterprise standard of Shanghai municipality Q/YXYY11 WNE-1A Engler Viscometer. It is suitable to determine ratio between the time used by an asphalt sample or other petroleum products sample flowing out of Engler viscometer under a certain temperature and volume, and that of distilled water flowing out of Engler viscometer at 25 ℃. The ratio is the Engler viscosity of asphalt or other petroleum products. Notification: The temperature of distilled water and the cubage of receiving flask may be different for other petroleum products measurement.

Tests for current transformer: Excitation curve and parameters test. Turns ratio test. Ratio and phase error test. Polarity mark check. Coil resistance measurement. Secondary loop burden measurement. Error line curve test for protection CT. Transient CT parameters test. CT nameplate guess. Saturation hysteresis loop curve measurement.

The instrument is a new high precision, digital full space inclination measurement device. It is used for direction orientation and inclination measurement during engineering borehole, directional borehole, horizontal borehole, connection borehole, and other drilling hole in the non-magnetic area. It can provide depth, tool face angle, dip angle and azimuth angle of borehole. It has been widely used in engineering, hydrology, oil field, coal field, and geology.

It is the necessary device for borehole determination. It contains a depth coder. The depth coder can be taken as paper moving signal of recorder, and it can digitally display measurement depth. It can be taken as depth sampling signal for borehole determination.

The instrument is designed and made as per the National Standard of People’s Republic of China GB/T4507 “Test Methods for Softening Point of Asphalt” and T0606 “Asphalt Softening Point Test (Ring and Ball Methods)” in the Industry Standard of People’s Republic of China JTJ052 Specifications and Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering. It is suitable to determine the softening point of asphalt, tar, liquid asphalt and other types of asphalt. It is the best choice of asphalt manufacturers, highway and bridge construction companies, college and universities, and research and development departments.
