ASTM D5133 Gel Index of Lubricating Oil Tester 

Product model: JF0732

Product Introduction

Brookfield scanning technology to measure the low temperature pumping performance and gel index of fresh, smoky and highly oxidized engine oils by continuously recording viscosity values over a wide temperature range (+20 to -70°C). Comply with ASTM D5133, D7110SH/T0732 and GB/T 11121 and other standard test methods and specify the instrument for ASTM D5133. 

How it works: The low temperature pumpability and gel index of unused and highly oxidized engine oils are measured by slowly and continuously lowering the measurement temperature, and both values are recorded simultaneously. A gel index higher than 12 can lead to engine failure under certain cooling conditions. This instrument is the only one capable of measuring the gel index of lubricants.

Features

1.Automatic calibration process, graphic display of calibration data; 

2.Multi-point temperature correction, you can also add temperature correction points; 

3.ADDITION@ analysis software, which can calibrate and analyze the linear accuracy of the viscometer very well; 

4.The key is automatically lifted and lowered, and the viscometer is automatically positioned; 

5. It has the function of locking the test tube to prevent the test tube from affecting the accuracy due to excessive viscosity; 

6.Automatically scan the viscosity, generate a gel curve, and automatically analyze the gel index and gel temperature; 

7. Use a linear curve to cool down, and the cooling speed can be edited;
