Coolant Analysis Instrument China Factory

Comprehensive Engine Protection via the Coolant Analysis Instrument

Introduction
Engine coolant must manage heat transfer, prevent cavitation, and inhibit corrosion throughout a range of operating conditions. The Coolant Analysis Instrument from Changsha Friend Experimental Analysis Instrument Co., Ltd. delivers a full panel of tests—thermal conductivity, cavitation potential, inhibitor concentration, and microbiological contamination—to maintain coolant system health.

Key Measurements

• Thermal Conductivity: A transient hot-wire sensor quantifies a coolant’s ability to transfer heat, ensuring efficient engine cooling under load.

• Cavitation Erosion Resistance: Ultrasonic transducers simulate pump-induced pressure fluctuations, measuring material loss on metal coupons to assess cavitation risk.

• Inhibitor Level Monitoring: Ion-selective electrodes determine concentrations of nitrite, molybdate, phosphate, or organic inhibitors.

• Microbial Activity: A fluorescence-based assay detects bacterial and fungal growth in water-glycol mixtures, critical for closed-loop cooling systems.

Instrument Features

• Integrated Sample Preconditioning: Temperature control (5 °C–90 °C) and degassing modules standardize sample state prior to measurement.

• Automated Calibration Checks: Internal standards enable nightly performance verification without operator input.

• Multi-User Data Management: User profiles and audit trails support compliance with quality-management systems.

Applications
Power plants, marine engines, and industrial compressors all benefit from regular coolant analysis to avoid overheating, corrosion, or biofouling. Maintenance teams use thermal conductivity data to adjust glycol/water ratios seasonally.

Best Practices
– Run inhibitor-specific calibration curves before each test batch.
– Clean cavitation test coupons after each cycle to avoid residue buildup.
– Store microbial assay reagents according to cold-chain guidelines.

With comprehensive coolant analysis, end users can detect early signs of coolant degradation, optimize maintenance schedules, and protect critical heat-exchange equipment.
