Purpose:

The instrument is designed and made as per T0623 “Asphalt
Saybolt Viscosity Test (Saybolt Viscometer Methods)” in the
Industry Standard JTJ052 Specification and Test Methods of
Bitumen and Bituminous Mixture for Highway Engineering. It
is used to determine viscosity of petroleum asphalt and
liquid petroleum asphalt. It is used to decide the
construction temperature.

Main structure and characteristics
The instrument is mainly composed of bath, bath temperature
controller, and measurement parameters display calculator
(calibration coefficient, time, viscosity, etc).
The instrument adopts microprocessor controlling technology
and has function of two-way determination. It can make
parallel determination for two samples at the same time. It
can digitally show test parameters and calculate average
value of test data. It can also convert Saybolt viscosity
into Engler viscosity or Kinematic viscosity. Only make
determination once, you can get three types of test data.
It is efficient and reliable.

Technical parameters
1. Power supply: AC 220V±10%, 50 Hz;
2. Types: Desktop;
3. Working mode: Two-way determination; parallel test;
4. Sample receiving bottle: 60±0.05ml;
5. Heating power: 1000 W;
6. Working temperature range of bath: room temperature
∼240.0°C;
7. Temperature controlling accuracy of bath: ±0.1°C;
8. Timing range: 0.0s∼999.9s;
9. Timing accuracy: ±0.1s;
10. Ambient temperature: ≤35°C;
11. Relative humidity: ≤85%
