Summary
The Scanning Brookfield measures the low-temperature pumpability and gelation index of new
oil, smoky and highly oxidized engine Oils by continuously
recording viscosity values in a wide temperature range.
This Low Temperature Viscosity/Gelation Index Test Apparatus is compilied with ASTM D5133, ASTM D7110, SH/T0732, GB/T 11121 and
other standard test methods, and it is specified instrument for
ASTM D5133.
Working principle: measure the low temperature pumpability and
gelation index of unused and highly oxidized engine oil by slowly
and continuously reducing the measuring temperature, and record the
two values at the same time. If the gelation index is higher than
12, the engine will fail under some cooling conditions. This Low Temperature Viscosity/Gelation Index Test Apparatus is the only one that can measure lubricant gelation index.
I. Main technical features
1. The Low Temperature Viscosity/Gelation Index Test Apparatus can automatic calibration process and graphic display of
calibration data;
2. The Low Temperature Viscosity/Gelation Index Test Apparatus has Multi point temperature correction, or add temperature
correction points by yourself;
3,The analysis software can be used to calibrate the viscometer and
analyze the linear accuracy;
4. One key automatic lifting structure, automatic positioning of
viscometer;
5. The Scanning Brookfield Low Temperature Viscosity/Gelation Index Test
Apparatus has the test tube locking function to prevent excessive viscosity
from driving the test tube to affect the accuracy;
6. The Low Temperature Viscosity/Gelation Index Test Apparatus can automatically scan viscosity, generate gelation curve, and
automatically analyze gelation index and gel temperature;
7. Low Temperature Viscosity/Gelation Index Test Apparatusadopts linear curve for cooling, and the cooling rate can be edited
