Selection Guide for Power Plant Water & Steam Monitoring: How to Choose the Suitable Hydrogen Conductivity Meter

Hydrogen conductivity serves as a core monitoring parameter for evaluating impurity accumulation, equipment corrosion and salt scaling in boiler feedwater, condensed water and steam circuits during water-steam quality management at thermal power plants and special equipment inspection institutions. Proper instrument selection is critical to unit operation safety and compliance of test data. Many procurement officers fail to distinguish online fixed analyzers from portable testing equipment during selection. Blind procurement will not only push up operation and maintenance costs, but also easily cause test data drift and non-compliance with industrial verification standards.

Fixed online hydrogen conductivity analyzers are only applicable to long-term continuous monitoring at fixed measuring points, and cannot meet the demands of multi-point on-site patrol inspection, instrument comparison and emergency water sampling testing. Imported portable models are plagued by high purchase costs, long delivery cycles and cumbersome maintenance of electrode consumables in later operation. To address these prevalent industry pain points, Zhongke Tk (Shandong) Intelligent Technology Co., Ltd. has devoted itself to the R&D of water-steam analytical instruments and launched a full lineup of hydrogen conductivity meters, including flagship models such as HC-100 portable hydrogen conductivity meter, HC-200 multi-parameter hydrogen conductivity meter and degassed hydrogen conductivity meter, which precisely cater to two core application scenarios: power plants and special equipment inspection institutes.

All instruments adopt the self-developed cation degassing and exchange structure independently researched by the company, which can automatically eliminate testing interference caused by ammonia and amines in water samples. The measuring resolution reaches 0.001 μS/cm, with a built-in intelligent temperature compensation algorithm that automatically converts test results to standard values at 25°C, fully complying with GB/T 6903 and DL/T industrial specifications for water and steam testing in the power sector. Among the product lineup, the HC-200 features a lightweight body and long-life lithium battery, ideal for circuit patrol inspection in equipment rooms. All series support extended multi-channel parameter measurement and are equipped with an in-depth degassing unit for precise analysis of high-interference water samples. Every model supports storage of up to 1,000 groups of test data and USB data export, satisfying traceability and filing requirements for inspection data.

Beyond the hydrogen conductivity product series, Zhongke Tk also provides matching silicate and phosphate analyzers to deliver one-stop integrated solutions for power station water-steam testing. Amid the wave of domestic substitution, purchasers shall prioritize three core indicators during model selection: independent R&D capacity of sensors, complete compliance certifications and efficient localized after-sales service response, so as to fundamentally avoid hidden troubles in subsequent operation.
