ASTM D1665 Digital Display Engler Viscometer for Tar / Heavy Oil Product

Feature
1. ASTM D1665
2. GD/B0622
3. A digital temperature controller
4. Engler viscometer
Introduction
It is used to determine the ratio obtained by dividing the flow time, in s, of a selected volume of sample 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 25 c.
Main characteristics
1. It is composed of main unit and temperature controlling device. The inner and outer containers are made of stainless steel. The inside of inner container has been specially processed, so its smooth finish meets test requirements.
2. Adopt a digital temperature controller having function of PID adjustment, so it is easy to preset parameters with high temperature controlling accuracy.
Main technical specification and parameters
1. Standard water value: 51± 1 s (It is at standard water temperature 20± 0.1 c, and 200 ml water; It can be converted into a value at 25± 0.1 c, and 50 ml water);
2. Temperature range: 0~100c;
3. Temperature controlling accuracy: ± 0.1c
4. Graduated flask: 100 ml;
5. Inner container: Made by stainless steel;
6. Power of electric heater: 550 W/220V;
7. Precision of electric stopwatch: 1/100 s;
