Dalian Petroleum Instrument Co. Ltd products

10 years after the 1st generation of the automatic distillation tester DSY-003Z launched, the 3rd generation DSY-003ZB with a built-in Windows ® based PC and a large touch screen monitor has been developed. DSY-003ZB is designed to perform automatic distillation of petroleum products like gasoline, fuel oils, kerosene, naphtha and other solvent products. DSY-003ZB can automatically control distillation rate, recovery volume and determinate the IBP, FBP, DP and residue corrections. 10 inch touch screen can display simultaneously the temperature of heater, steam, cooling tube, receiver compartment. Three kinds of curves (distillation rate, heating temperature, steam temperature) can be displayed in real-time as well.

4 kinds of tests can be done by the one instrument. 2 bath and 4 pole, the bath temperature controlled alone. Digital display control temperature of cooling bath, high precision PID controller. Digital display time, timing automatic. Temperature control: 0~minus 69?. Constant temperature precision: ±0.5?. Machine Power: 1800W. Electrical Requirement: AC220V±22V  50Hz. 

PC controlled, automatic action include: pressure and temperature collection and calibration, release, leaking test, bomb dropping,  etermination of break point, bomb raising, etc. Unique air bath improve the accuracy of test.
