HKL-1831 Apparatus for Roll stability of Lubricating Grease
Overview
HKL-1831 Apparatus for Roll stability of Lubricating Grease conforms to ASTM D1831 Standard Test Method for Roll Stability of Lubricating Grease. Cone penetration of an approximately 50-g aliquot of lubricating grease is determined. The grease is then subjected to low shear at 20 to 35°C (68 to 95°F) for 2h ± 5min in a standard roll stability apparatus, before the cone penetration is a gain measured. The difference between the cone penetration before working and the cone penetration after is used as a measure of the effect to flow shear working on grease consistency.
Features
This instrument uses an imported temperature controller for high-precision regulation.
The instrument has two working units capable of simultaneous sample processing.
Most components of the instrument are made of stainless steel, making it wear-resistant and corrosion-resistant.

FAQ
Q1: What standards does this product (HKL-1831 Apparatus for Roll stability of Lubricating Grease) comply with?
A: HKL-1831 Apparatus for Roll stability of Lubricating Grease conforms to ASTM D1831 Standard Test Method for Roll StaThe HKL-1831 grease rolling stability test apparatus conforms to the ASTM D1831 standard test method for grease rolling stability. First, the cone penetration of approximately 50 grams of grease sample is measured. Then, the grease is placed in the standard rolling stability test apparatus and subjected to a low-shear test at 20 to 35°C (68 to 95°F) for 2 hours ± 5 minutes, after which the cone penetration is measured again. The difference in cone penetration before and after the test is used to measure the effect of the flow shear test on the grease consistency.
Q2: What is the applicable scope and significance of HKL-1831 Apparatus for Roll stability of Lubricating Grease?
A: This test method covers the determination of grease consistency changes by cone penetration in a roll stability test apparatus. Roll stability testing is widely used in specifications. The significance of the test results lies in their ability to show the direction of grease consistency changes that may occur during actual use. However, a precise correlation has not yet been established between the test results and the shear stability in actual use.
Q3: What is the minimum order quantity? How long is the delivery lead time?
A: The minimum order quantity is one piece, and delivery will take approximately 20 days after prepayment.
Q4: Do you provide product operation manuals or technical documentation?
A: Yes, we offer electronic versions of product manuals, quick start guides, application examples, and standard operating procedures (SOPs). You can obtain these materials by logging into the download center on our official website or by contacting customer service.
Q5: Do you provide online training services?
A: If needed, we will provide online installation and debugging services, as well as comprehensive operation training. In addition, we offer 24/7 online training support for end users.
