Laboratories that test petrochemicals, lubricants and related products are under pressure to maintain D445 compliance as sample volumes rise and staffing costs increase. Automated viscometry systems are being evaluated for their ability to deliver consistent measurements while reducing hands-on work. The CAV 4.2 is a dual-bath automated viscometer whose published specifications cover those laboratory requirements.
Technical specifications list a temperature range of 15°C to 150°C and a viscosity range of 0.5 to 10,000 mm²/s. The system can process up to 24 tests per hour and includes a preheating function that covers ambient temperature to 100°C.
| Parameter | Technical specification |
|---|---|
| Temperature range | 15°C to 150°C |
| Viscosity range | 0.5 to 10,000 mm²/s |
| Throughput | Up to 24 tests per hour |
| Preheating function | Ambient temperature to 100°C |
The unit uses a modular dual-bath design that provides redundancy for continuous testing and allows two independent baths to operate at different temperatures at the same time. For laboratories that frequently switch test temperatures, the configuration reduces equipment preparation time.
Independent sample handlers support unattended operation, while status indicators give operators a visual read on instrument activity without requiring constant presence at the unit.
Beyond measurement accuracy, laboratory managers are weighing long-term operating costs. The CAV 4.2 includes design features intended to reduce solvent use, service calls and routine maintenance time.
The combination of dual-bath automation, independent sample handling and lower solvent consumption is intended to help laboratories manage throughput and operating expenses without compromising D445 testing requirements.
