High-Temperature High-Shear Capillary Viscometer (HTHS)
ASTM D5481 Standard Test Method for Measuring Apparent Viscosity at High-Temperature and High-Shear Rate by Multicell Capillary Viscometer
  • Impressive throughput: 15 - 20 samples per hour
  • Reduced role for operator enhances repeatability and reproducibility
  • One button operation. Just load sample, set pressure, and press start
  • Variable temperature and shear rate for research applications
  • Fill valve safety switch, resettable over-temperature cutoff
  • CE certification
  • HTHS viscosity calculation software for Windows®
HTHS Ⅱ Series
The HTHS determines the viscosity of engine oils under conditions of high shear at a temperature of 150°C. Pressurized gas is used to force an oil sample through a capillary maintained at 150°C ±0.1°C to obtain the required shear rate (normally 106 sec–1). Other temperatures and shear rates can also be used. The five viscometric cells in the instrument may be operated in rapid succession. A digital stop-clock measures flow (efflux) time within 0.01 seconds. Flow times, temperature and pressure are all displayed digitally. A sample flush cycle eliminates the need for solvent cleaning during normal HTHS operation. Other features include built-in, replaceable filters and a pressure relief valve which protects against over-pressurization. The pressurized gas(not supplied) may be carbon dioxide, nitrogen, or an inert gas.

Features:

The new CANNON® High-Temperature High-Shear (HTHS) Capillary Viscometer is designed to determine the viscosity of engine oils and other oils under conditions of high shear at high temperatures. The HTHS is capable of testing at 1.4x106 s-1 at 150°C, and meets all precision specifications of ASTM D 5481.

Oil samples are introduced into the viscometric cells and then flow through small glass capillaries under pressure to achieve the desired shear rate. The HTHS monitors each test and displays the results. You can also analyze, display, and print test data with the computer software.

Components:

The HTHS viscometer is supplied with a digital temperature control system (variable from 30°C to 150°C), a digital pressure measuring system, automatic timer, and the High Shear Viscosity Calculator (Standalone software package for Windows® for HTHS data analysis and output).
