Description
Purpose
The instrument is designed and made as per T***2 “Asphalt
Engler Viscosity Test (Engler Viscometer Methods)” in the Industry
Standard JTJ**2 Specification and Test Methods of Bitumen and
Bituminous Mixture for Highway Engineering, the National
Standard GB/T**6 “Test Methods for Engler Viscosity of Petroleum
Products”, and Company Standard of Shanghai Q/YXYY*1 “WNE*1A Engler
Viscometer”. 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 *5 °C.
Main technical 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: *1±1 s (It is at standard water
temperature *0±0.1 °C, and **0 ml water; it can be converted into a
value at *5±0.1 °C, and *0 ml water);
2. Temperature range: 0~**0°C;
3. Temperature controlling accuracy: ±0.1°C;
4. Thermometer: As per T***2;
5. Graduated flask: **0 ml;
6. Inner container: Made by stainless steel;
7. Power of electric heater: **0 W/**0V;
8. Precision of electric stopwatch: 1/**0 s
