HKL-5481 High-Temperature and High-Shear Rate Apparent Viscosity Tester (HTHS)
Overview
The HKL-5481 High-Temperature and High-Shear Rate Apparent Viscosity Tester (HTHS) conforms to ASTM D5481 Standard Test Method for Measuring Apparent Viscosity at High-Temperature and High-Shear Rate by Multicell Capillary Viscometer. It covers the laboratory determination of high-temperature high-shear (HTHS) viscosity of engine oil at a temperature of 150℃ using a multicell capillary viscometer containing pressure, temperature, and timing instrumentation. The shear rate for this test method corresponds to an apparent shear rate at the wall of 1.4 million reciprocal seconds (1.4×106 s-1).This shear rate has been found to decrease the discrepancy between this test method and other high temperature high-shear test methods used for engine oil specifications. Viscosities are determined directly from calibrations that have been established with Newtonian oils with viscosities from 2 to 5 mPa·s at 150℃.
Features
Shear Viscosity Computation Software is compatible with Windows OS to facilitate smooth data handling.
Temperature Control: Equipped with a digital temperature controller by Fuji Electric from Japan, combining high accuracy, excellent resistance to interference, and a long operating life.
The core unit uses an imported programmable logic controller (PLC) along with a very large and sensitive LCD touch screen. This combination not only ensures accurate control but also makes the display user-friendly. Besides, it has a great ability to resist interference, hardly ever breaks down, and entails very little maintenance expense.
The multiple glass capillary viscometer method is capable of measuring quickly and very accurately. Since it does not have any mechanical rotating parts or components that wear by moving, it is characterized by long-term, fault-free operation.
The test doesn’t need any solvent cleaning, just a small amount of fresh sample to rinse the viscometer. It results in a big saving on usage costs.
The testing process is completely automatic. Just add the sample, let it stabilize at a constant temperature for 15 minutes, then wipe off any excess sample, close the valve, and press Start. The internal program measures the test pressure and the efflux time of the sample at 150°C by itself. These two parameters are then used as inputs for specific kinematic viscosity calculation software to find out the kinematic viscosity of the sample. The internal operating program conducts the test and computes the kinematic viscosity automatically.
Calibration is done with the help of a viscosity standard oil imported from USA. This way is easy and quick. Research type of clients can select different temperatures and the corresponding shear rates.

FAQ
Q1: What standards does this product (HKL-5481 High-Temperature and High-Shear Rate Apparent Viscosity Tester (HTHS)) comply with?
A: The HKL-5481 High-Temperature and High-Shear Rate Apparent Viscosity Tester (HTHS) conforms to ASTM D5481 Standard Test Method for Measuring Apparent Viscosity at High-Temperature and High-Shear Rate by Multicell Capillary Viscometer. It covers the laboratory determination of high-temperature high-shear (HTHS) viscosity of engine oil at a temperature of 150℃ using a multicell capillary viscometer containing pressure, temperature, and timing instrumentation. The shear rate for this test method corresponds to an apparent shear rate at the wall of 1.4 million reciprocal seconds (1.4×106 s-1).This shear rate has been found to decrease the discrepancy between this test method and other high temperature high-shear test methods used for engine oil specifications. Viscosities are determined directly from calibrations that have been established with Newtonian oils with viscosities from 2 to 5 mPa·s at 150℃.
Q2: Significance and use of HKL-5481 High-Temperature and High-Shear Rate Apparent Viscosity Tester (HTHS)?
A: Viscosity is an important property of fluid lubricants. The viscosity of all fluids varies with temperature. Many common petroleum lubricants are non-Newtonian: their viscosity also varies with shear rate. The usefulness of the viscosity of lubricants is greatest when the viscosity is measured at or near the conditions of shear rate and temperature that the lubricants will experience in service. The conditions of shear rate and temperature of this test method are thought to be representative of those in the bearing of automotive engines in severe service.
Q3: Do you provide samples?
A: If you want to get small consumables or accessories, first you need to have a negotiation. The samples will be given only after paying the sample fee and the shipping costs. However, for instrument-type products, we suggest seeing case studies of similar users or visiting for a demonstration because these products are usually of high value.
Q4: Do you provide product operation manuals or technical documentation?
A: Yes, we offer electronic versions of product manuals, quick operation guides, application cases, and standard operating procedures (SOPs). These can be accessed by logging into the download center on our official website or by contacting customer service to request them.
Q5: 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.
