Characteristics of Test Laboratory for Transformer Oil
a). We exclusively adopt second analysis method, ˇ§Oil Stripperˇ¨ approved by ASTM USA that is better than traditional vacuum extraction.
b). Test laboratory has not only acquired accreditation of GE and Shimadzu but also associated with over 100 labs in the United States to proceed comparison and  modification of accuracy twice per year.
c). Regarding sampling service, we uniformly make use of Syringe adopted by each lab in the United States to draw up oil. The specification for such Syringe is capacity at 30ml including nylon valve (33x20x22mm). As for this Syringe, if we pull its piston rod from 0ml to 20ml, hold for 60 seconds and then set free the piston, the air inside Syringe needs to be less than 3ml. Besides, Syringe itself and piston rod have to be corresponding and numbered by the manufacturers.
d). US manufacturer will provide us with laboratory-ranked standard oil and air in order that our laboratory can carry out calibration. Not only to that, our laboratory will modify accuracy twice an year on basis of the values made by hundreds of laboratories in the United States in order to keep accuracy at all times.

Indeed, our offer is the excellent service as same as the laboratory in the United States. But the charge is the lowest in order to serve the industry and to enable them not only to find malfunction earlier but also to avoid any severe loss during power failure caused by burnout of the transformer.
