HKL-942 Oxidation Stability Tester for Lubricating Greases
Overview
HKL-942 Oxidation Stability Tester for Lubricating Greases conforms to the ASTM D942 Standard Test Method for Oxidation Stability of Lubricating Greases by the Oxygen Pressure Vessel Method. The sample of grease is oxidized in a pressure vessel heated to 99°C (210℉) and filled with oxygen at 110 psi (758kPa). Pressure is observed and recorded at stated intervals. The degree of oxidation after a given period of time is determined by the corresponding decrease in oxygen pressure.

FAQ
Q1: What standards does this product (HKL-942 Grease Oxidation Stability Tester) meet?
A: HKL-942 Oxidation Stability Tester for Lubricating Greases conforms to the ASTM D942 Standard Test Method for Oxidation Stability of Lubricating Greases by the Oxygen Pressure Vessel Method. The sample of grease is oxidized in a pressure vessel heated to 99°C (210℉) and filled with oxygen at 110 psi (758kPa). Pressure is observed and recorded at stated intervals. The degree of oxidation after a given period of time is determined by the corresponding decrease in oxygen pressure.
Q2: Significance and use of HKL-942 Oxidation Stability Tester for Lubricating Greases?
A: This test method measures the net change in pressure resulting from consumption of oxygen by oxidation and gain in pressure due to formation of volatile oxidation by-products. This test method may be used for quality control to indicate batch-to-batch uniformity. It predicts neither the stability of greases under dynamic service conditions, nor the stability of greases stored in containers for long periods, nor the stability of films of greases on bearings and motor parts. It should not be used to estimate the relative oxidation resistance of different grease types.
Q3: What is the minimum order quantity? How long is the delivery lead time?
A: The minimum order quantity is one unit, and delivery is approximately 20 days after advance payment.
Q4: Do you provide product operation manuals or technical documents?
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.
