ASTM D445, ASTM D7483

For oil, gas, and supercritical fluids, the ViscoLab PVT delivers accurate, fast, and reliable viscosity measurements. In high-pressure environments, correctly analyzing precious samples is as challenging as it is critical. The ViscoLab PVT is the gold standard for high pressure viscosity analysis. This high pressure viscometer operates at pressures up to 20,000 psi (up to 30,000 psi with a special option), and controls temperatures from -5° to 185°C with minimal warm-up time.

Safe and cost-effective to own and operate, the ViscoLab PVT is mercury-free and requires only 6 ml of sample. It also provides statistical certainty that ensures sample conditions are stable, accurate, and repeatable. It measures gas and gas condensates in addition to fluid samples. The ViscoLab PVTs extraordinary capabilities make it an ideal choice for the most critical and challenging applications.

This high pressure viscometer combines a ViscoPro processor with either a Cambridge Viscosity 440 or 443 sensor. The 440 sensor provides continuous operation up to 20,000 psi while the 443 sensor is designed to operate up to 30,000 psi. The system employs an integrated re-circulating bath for tight temperature control.
