Purpose
The instrument is designed and made as per the National Standard GB/T266, ASTM D 1665 "Test Methods for Engler Viscosity of Petroleum Products" and the Industry Standard JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering.
It is used to determine the ratio obtained by dividing the time of flow, in s, of 200 ml of material using an Engler viscometer at a selected temperature by a factor representing the time of flow, in s, for an equal volume of water at 20 °C. The ratio is the Engler viscosity of the sample. The instrument can make determination for 2 samples at the same time in the same temperature environment. It can also calculate the average value of these test results. It is the best instrument for Engler viscosity of petroleum products and bituminous materials determination.
I. Main technical features
1. The instrument adopts desktop, all-in-one and double inner crucible structure. Both of inner and outer crucibles adopt stainless materials. Inner crucible has been specially processed. The smooth finish corresponds with the test requirements.
2. The flow out time adopts digital display. Can do parallel determination for 2 samples at the same time. Easy to use and efficiency is high.
3. The temperature controller adopts digital display temperature controller with P,I,D position regulatory function. Easy to set the parameters and temperature controlling precision is high.
