Testing Principles and Analytical Methodologies
Electrochemical Conductivity Measurement
The JL-XC Series utilizes a four-electrode conductivity cell to eliminate polarization effects, ensuring precise readings even in ultra-pure water (UPW) with conductivity below 1 µS/cm. This is essential in semiconductor fabrication, where ionic contamination can lead to wafer defects.
Optical Turbidity and Organic Contaminant Detection
A dual-wavelength LED-photodiode system measures turbidity and detects organic impurities via UV-Vis absorbance at 254 nm. This method aligns with USP and ASTM D859 for water purity in pharmaceutical and medical device industries.
Real-Time ORP Monitoring for Sterilization Validation
Oxidation-reduction potential (ORP) is critical in assessing the efficacy of sterilization processes in medical and aerospace applications. The JL-XC Series employs a platinum ORP electrode with automatic temperature compensation, ensuring reliable readings in autoclave rinse water and clean-in-place (CIP) systems.
Industry-Specific Applications of the JL-XC Series
Electronics Manufacturing: Preventing Ionic Contamination
In printed circuit board (PCB) production, even trace levels of ionic contaminants (e.g., Cl⁻, SO₄²⁻) can cause electrochemical migration, leading to short circuits. The JL-XC Series detects these impurities at sub-ppb levels, ensuring compliance with IPC-5701 and JIS K 0557.
Automotive Electronics: Coolant and Battery Water Analysis
Electric vehicle (EV) battery cooling systems require ultrapure water to prevent corrosion and mineral deposition. The device’s high-resolution TDS sensor monitors coolant quality, reducing maintenance intervals and improving thermal efficiency.
Medical Device Sterilization: Validating Water Purity
Medical device manufacturers must adhere to ISO 13485 and AAMI TIR34 for water used in sterilization processes. The JL-XC Series provides continuous microbial endotoxin screening via ATP bioluminescence correlation, ensuring compliance with FDA and EU MDR regulations.
Competitive Advantages Over Conventional Water Testers
- Multi-Parameter Synchronization – Unlike single-function testers, the JL-XC Series simultaneously measures pH, conductivity, TDS, ORP, and temperature, reducing analysis time by 60%.
- Automated Data Logging and Cloud Integration – Supports Modbus RTU and Wi-Fi connectivity, enabling real-time monitoring in Industry 4.0 environments.
- Extended Sensor Lifespan – A patented anti-fouling electrode coating reduces maintenance frequency in high-particulate environments.
Regulatory Compliance and Standardization
The JL-XC Series is certified under:
- IEC 61010-1 (Safety Requirements for Electrical Equipment)
- ISO 9001 (Quality Management Systems)
- RoHS & REACH (Restriction of Hazardous Substances)
Its calibration protocols align with NIST-traceable standards, ensuring global acceptance in regulated industries.
