VISCOMETER BATH AZA0951
The AZA0951 Viscometer Bath from AZA Lab is a precision-engineered laboratory instrument developed to support high-temperature viscosity-related testing and evaporation loss determination of lubricating oils, in line with the intent and operational requirements of ASTM D445 and associated lubricant evaluation practices. The system is specifically designed to provide stable thermal conditions, controlled suction, and repeatable test environments, which are critical for evaluating oil volatility, thermal stability, and performance at elevated temperatures.
In modern lubricant formulation and quality assurance, evaporation loss and viscosity stability are key indicators of an oil’s suitability for high-temperature service conditions, such as internal combustion engines, turbines, compressors, and industrial machinery. The AZA0951 Viscometer Bath addresses these requirements by combining uniform metal bath heating, automatic temperature regulation, and vacuum-assisted operation, ensuring accurate, consistent, and reproducible test results
Description
Design Philosophy and Construction
The AZA0951 is built around a high-efficiency aluminium alloy metal bath, selected for its superior thermal conductivity, mechanical strength, and resistance to deformation under prolonged high-temperature operation. This construction ensures:
-
Uniform heat distribution across the bath
-
Minimal temperature gradients
-
Enhanced insulation and reduced heat loss
-
Long operational life in continuous laboratory use
The instrument is divided into two functional sections:
-
Main Heating and Control Unit
-
Auxiliary Vacuum and Pressure Stabilization Unit
This modular design improves operational stability, simplifies maintenance, and enhances overall system reliability.
Operating Principle
The AZA0951 Viscometer Bath operates by maintaining a precisely controlled thermal environment for lubricant samples while applying controlled suction via a vacuum pump. During testing, the oil sample is exposed to elevated temperatures under regulated conditions, allowing accurate evaluation of:
-
Evaporation loss characteristics
-
High-temperature viscosity behavior
-
Thermal degradation tendencies
The integrated control system ensures that temperature, timing, and suction parameters remain within predefined limits throughout the test cycle, thereby minimizing operator dependency and improving repeatability.
