Water quality testing is a critical process across multiple industries, ensuring compliance with environmental regulations, operational safety, and product reliability. In sectors such as electrical and electronic equipment manufacturing, automotive electronics, and medical devices, contaminants in water—whether used in cooling systems, cleaning processes, or production lines—can lead to corrosion, electrical failures, or compromised product integrity.
This guide examines the methodologies, instrumentation, and standards governing water quality testing, with a focus on advanced analytical equipment such as the LISUN JL-XC Series, a high-precision solution for detecting impurities in industrial water systems.
Water quality is evaluated based on multiple physicochemical and biological indicators, each influencing industrial processes differently. The most critical parameters include:
Each parameter requires specialized instrumentation for accurate measurement, ensuring compliance with standards such as ISO 17025, ASTM D1193, and IEC 60754 for electrical safety.
The LISUN JL-XC Series is engineered for high-accuracy water quality analysis, integrating multi-parameter detection with real-time data logging. Designed for industrial applications, it meets stringent requirements in sectors where water purity directly impacts product performance.

Q1: How often should the JL-XC Series be recalibrated in high-usage environments?
A: In continuous monitoring applications (e.g., semiconductor plants), recalibrate every 72 hours. For intermittent use, monthly calibration suffices.
Q2: Can the JL-XC measure ultrapure water (resistivity >18 MΩ·cm)?
A: Yes, its high-sensitivity conductivity sensor (0.01 µS/cm resolution) is suitable for ultrapure water analysis.
Q3: Is the device compatible with non-aqueous coolants in automotive testing?
A: No, the sensors are optimized for aqueous solutions. For glycol-based coolants, use specialized hydrocarbon analyzers.
Q4: What is the expected lifespan of the DO sensor?
A: The optical DO sensor lasts approximately 2–3 years under continuous use, depending on exposure to UV light and oxidizing agents.
Q5: Does the JL-XC support wireless data export for IoT integration?
A: Yes, it includes Bluetooth and RS-485 outputs for integration with SCADA and LIMS platforms.
