Precise, absolute moisture measurement in gas streams

De voordelen van het product

Accurate moisture measurement in gas streams is essential for the quality, safety, and efficiency of industrial processes. MEECO analyzers operate according to Faraday’s Law of Electrolysis, using P₂O₅-based sensors that provide a direct and absolute measurement method. Within the measuring cell, water vapor from the gas sample is fully absorbed and electrolytically decomposed, generating an electrical current directly proportional to the amount of moisture, even at concentrations down to parts per billion (ppb).

This primary measurement principle delivers drift-free, traceable, and highly stable readings without the need for calibration or reference gases. Operators gain real-time process insight into gas moisture levels, crucial for process optimization, quality assurance, and safety in production, distribution, and laboratory environments.

MEECO: Globally recognized leader in electrolytic moisture analysis

Since 1948, MEECO has been a pioneer in electrolytic moisture analysis. The U.S.-based company designs analyzers trusted worldwide in sectors such as (petro)chemicals, energy, gas production and distribution, medical gases, pharmaceuticals, semiconductors, and research laboratories. 

MEECO’s technology is known for its long-term stability, high accuracy, and minimal maintenance requirements. With robust construction, integrated pressure control, and easy integration into process or laboratory setups, MEECO analyzers deliver reliable results even under harsh conditions or when exposed to dry or corrosive gases.
