In industrial settings, the condition of oil directly determines equipment lifespan and operating costs. Traditional monitoring often requires multiple instruments—thermometers, viscometers, and densitometers—which not only takes up space but is also prone to misjudgments due to inconsistent synchronization.
The ZH-600 six-parameter oil quality sensor, developed by ZHYQ, simultaneously measures six key parameters: temperature, dynamic viscosity, density, dielectric constant, water activity, and water content—with a single installation, allowing equipment managers to gain a comprehensive view of oil quality.

The practical value of application scenarios
Hydraulic systems (pump stations, cranes)

Typical issues: Increased temperature causes viscosity loss, and oil aging accelerates wear.
The value of the six-parameter oil quality sensor: Real-time monitoring of viscosity and temperature provides early warning and optimizes refueling strategies.
Gearboxes (Marine and Mining Equipment)

Typical Problems: Water content and impurity accumulation leading to bearing failure
The Value of Six-Parameter Oil Quality Sensors: Detecting oil cleanliness through water content and dielectric constant allows for timely replacement or cleaning.
Diesel Generators/Turbine Generators

Typical Problem: Fuel Dilution Leads to Decreased Efficiency
The Value of a Six-Parameter Oil Quality Sensor: Simultaneously monitors fuel viscosity and density to ensure optimal engine operation.
Aviation Fuel System

Typical Problem: Trace Moisture Affects Ignition Performance
The Value of Six-Parameter Fuel Quality Sensors: Water Activity Testing Can Prevent Potential Safety Hazards
Air Compressor & Transformer Oil

Typical Problem: Prolonged High Temperatures Lead to Oil Degradation
The Value of Six-Parameter Oil Quality Sensors: Dual Monitoring of Temperature and Viscosity Prevents Downtime Due to Oil Failure
From hydraulics to aviation fuel, whether it is industrial equipment or critical systems, the ZH-600 six-parameter oil quality sensor allows you to identify risks in advance, extend service life and reduce maintenance costs.
