255The distillation range tester for petroleum products is based on the standards of the People's Republic of ChinaGB/T255Petroleum Product Distillation Range Determination Method, Industry Standard of the People's Republic of ChinaSH/T 0121Designed in accordance with the requirements specified in the Technical Conditions for Distillation Range Measurement Devices of Petroleum Products, applicable to international standardsGB/T255The determination method is used to determine the fraction composition of liquid fuels, solvent oils, and light petroleum products.

255The distillation range tester for petroleum products is an integrated structure with a novel design, reasonable structure, convenient use, and meets the requirements ofGB/T255The requirements specified by the standards.
Adopting an integral lifting mechanism, the heating furnace is easy to adjust for ascending and descending, and runs smoothly.
The inner tank of the water bath is made of stainless steel material, which is corrosion-resistant and durable.
The water bath has a heating function, and the temperature control system adopts a microcomputer chip processor, with high temperature control accuracy and strong functions. Simultaneously equipped with low water level protection function.
The heating furnace adopts electronic voltage regulation technology to achieve continuous and stepless adjustment of heating power.
