Saybolt Viscometer – Electrically Heated with Energy Regulator (DVI Brand)
Product Overview
The DVI Saybolt Viscometer is a precision laboratory instrument designed for the empirical determination of the Saybolt Universal or Saybolt Furol viscosity of petroleum products. This model is ideal for testing lubricants, fuel oils, and bituminous materials at specified temperatures between 21 and 99°C (70 and 210°F). By measuring the efflux time of a 60 ml sample through a calibrated orifice, users can accurately characterize fluid flow resistance in accordance with international standards.
Robust Construction and Design
Built for durability and long-term reliability in demanding laboratory environments, the apparatus features a double-walled bath constructed from corrosion-resistant materials. The internal viscometer cup is typically crafted from brass or stainless steel to ensure consistent thermal conductivity and resistance to chemical wear. The assembly is mounted on a stable base equipped with leveling screws to maintain perfect vertical alignment during testing, which is critical for accurate results.
Simplified Temperature Control
This specific model utilizes an analog energy regulator for temperature management, providing a straightforward and cost-effective solution for routine analysis. The electrical immersion heating system efficiently brings the bath medium to the required temperature. For precise monitoring, the unit includes a thermometer support for an ASTM-calibrated glass thermometer. While the standard unit provides the necessary heating and regulation, an IP Thermometer is available as an optional accessory for users requiring specific standard compliance.
Key Features
- ASTM Compliance: Designed to meet the requirements of ASTM D88 standards for Saybolt viscosity testing.
- Dual Orifice Capability: Compatible with both Universal and Furol orifices, allowing for the testing of a wide range of viscosities, from light distillates to heavy residual materials.
- Efficient Bath System: The double-walled, oil-medium bath ensures uniform heating and temperature stability throughout the test duration.
- Easy Maintenance: Features a built-in drainage valve for the bath medium and a simple design that allows for thorough cleaning of the viscometer tube and gallery.
- Standardized Measurement: Precisely measures the time required for a 60 ml effluent volume, providing industry-standard SUS and SFS readings.
