This instrument is designed in accordance with the requirements specified in GB/T 255 “Test Method for Distillation Range of Petroleum Products” and SH/T 0121 “Technical Specifications for Distillation Range Determination Devices of Petroleum Products”. It is used to determine the distillate composition of liquid fuels, solvent oils and light petroleum products.

Main features:

1. Adopting an integral lifting mechanism, the heating furnace can be adjusted up and down conveniently and runs smoothly.

2. The water bath adopts a stainless steel structure, which is corrosion-resistant and durable.

3. The heating furnace uses electronic voltage regulation technology to realize continuous and stepless adjustment of heating power.
