DV2TLV
High-temperature Viscometer
Range: 2.5–500,000 mPa·s- 5-inch IPS touchscreen
- Heating chamber from ambient temperature to 300 °C
- Temperature accuracy ±0.1 °C
- 15 to 25 mL small-sample coaxial-cylinder configuration
- Bluetooth and viscosity-temperature curve support
DV2TLV is a heated small-sample rotational-viscometer configuration for viscosity measurements at elevated sample temperatures. The archived speed range is 0.1–200 rpm, with spindle Nos. 21, 27, 28 and 29 listed for the measuring system. Specify the actual test temperature, sample and cup/spindle combination so the heating package and usable viscosity range can be confirmed for the supplied revision.

Which maximum temperature should I specify for the DV2TLV?
Confirm the operating limit of the supplied heater, cup and temperature-sensing arrangement as a complete configuration. Available high-temperature records contain revision differences; obtain a model-specific statement for the required sample temperature instead of relying on a series headline.
How much sample does the DV2TLV need?
The archived measuring-system description lists 15–25 mL. Confirm the fill volume for the selected spindle and heated cup, including the loading and immersion procedure, before using that figure in a test plan.
How should I select a DV2TLV spindle and speed?
The archived speed range is 0.1–200 rpm. Request the working-range table for the supplied spindle/cup geometry at the intended test temperature. The overall catalog range does not mean every spindle reaches both limits.
Can an ambient-temperature test procedure be transferred directly to the DV2TLV?
Review sample conditioning, contact materials, temperature measurement and reading time first. Confirm any method-specific requirements and obtain the supplied operating and cleaning instructions before testing heated samples.
