Refrigerated Kinematic Viscosity Bath with Optical Flow Detection System for Fuel Testing Instrument

The Low-Temperature Kinematic Viscosity Bath is designed to measure the kinematic viscosity of petroleum and petrochemical products using calibrated glass capillary viscometers under precisely controlled temperature conditions. It supports viscosity testing under gravity or vacuum in accordance with applicable test methods.

The system accommodates four glass capillary viscometers and supports automated viscosity measurement when equipped with compatible optical detection assemblies. Optical sensors measure sample flow, while the integrated control system calculates viscosity results and records sample efflux times.

The bath features microprocessor-based PID temperature control, dual digital displays, and a two-decimal calibration offset. A clear, evacuated Dewar flask and glare-free fluorescent backlighting provide excellent visibility during testing. Air-cooled hermetic compressors using CFC-free refrigerants provide efficient low-temperature operation.

Integrated safety systems include primary and redundant overtemperature protection, probe-disconnection protection, and a low-liquid-level sensor. These safety circuits interrupt heater power and prevent operation until the fault is corrected.
