Absolute and Kinematic Viscosity Baths are precision temperature-controlled liquid baths used to determine the viscosity of various fluids such as lubricants, fuels, and polymers. These baths are designed to maintain highly stable thermal environments to ensure accurate and repeatable viscosity measurements.

They support two types of viscosity testing:

• Absolute Viscosity (Dynamic Viscosity): Measures the internal resistance of a fluid to flow.

• Kinematic Viscosity: Measures the fluid's resistance to flow under gravity, accounting for its density.

• Precise Digital Temperature Control (PID Controller)

• Uniform Temperature Distribution via stirring

• High-visibility tank (especially for kinematic testing)

• Multi-tube capacity for increased productivity

• Compliance with ASTM and ISO Standards, such as ASTM D445, D446, D2170, ISO 3104

• Built-in Lighting for easy observation of viscometer operation

• Safety Features: Over-temp cutoffs, low liquid level protection, alarms

• Petroleum Industry: Lubricants, base oils, fuels

• Automotive and Aerospace: Gear oils, brake fluids, hydraulic fluids

• Pharmaceuticals and Chemicals: Polymers, surfactants, resins

• Quality Control & R&D Labs

• Automated Viscosity Measurement Systems

• Integrated Timers for flow time in kinematic tests

• Data Logging and PC Connectivity

• Temperature Programming for multi-step testing

Both types of baths are essential tools for precise viscosity determination, crucial for product formulation, compliance, and performance assurance in many industries.
