Viscometers

The New DV2T Viscometer features a 5-inch color display to guide users through test creation and data gathering for fast and easy viscosity measurements. The DV2T also offers powerful new programming capabilities and results analysis including data averaging and QC limits with alarms. User instructions with multi-step test protocols can be created using the new Program Generator Software and uploaded to the DV2T through a USB Flash Drive (both included with instrument). Test Data can be recorded directly on a local printer or sent to a PC. Additional automated control and data collection can be achieved with optional RheocalcT software.

Carrying Case

For elevated temperature testing of hot melts, asphalt, wax and polymers

The difficulty with viscosity measurements of hot melts and liquids at elevated temperatures has been in maintaining accurate temperature control that is consistent from sample to sample so that meaningful data could be obtained. The Brookfield Thermosel solves this problem by providing a stable, precisely controlled sample environment. This, together with the inherent accuracy of the Brookfield Viscometers, is fundamental to the Thermosel System, which produces viscosity measurements that are not only accurate but entirely reproducible.

Several factors contribute to the stable environment:

• Non-fluctuating temperature control.
• Small sample volume and insulated sample chamber which reduces temperature gradients within the sample.
• The rotating spindle, which acts as a built-in stirring device.
• The test procedure is quite straightforward. Once familiar with the system, unskilled operators can easily produce accurate, reproducible data.

FEATURES & BENEFITS

• Provides control of sample temperature up to +300°C
• Programmable Controller offers single set point or up to 10 programmable set points. Temperature ramping between set points is possible if used with RheocalcT Software
  Note: Requires optional cable HT-106 when QC control with RheocalcT is implemented.
• Compatible with standard Brookfield Viscometers and DV3T Rheometers
  Note: requires optional cable DVP-141 when controlled by DV3T Rheometer
• Supplied with reusable stainless steel sample container and five disposable aluminum sample chambers
• Outputs: 0-4 Vdc for chart recorder; RS-232 for use with DV3T and/or RheocalcT

DISPOSABLE SPINDLE/CHAMBERS OPTION

Disposable sample chamber with Disposable Spindle SC4-27D* is ideal for asphalts or any difficult-to-clean material. Requires special adapter (SC4-DSY).
*Optional SC4-27D is available in quantities of 100, (SC4-27D-100).

The Thermosel is also available to purchase with a magnetic spindle couple system. This option allows spindles to be quickly attached and removed, and may also help prevent against damage that can occur from frequent spindle changes or multiple users. Please contact Brookfield or an authorized dealer for details and part numbers.
