Product Briefing Outline: MEECO has introduced the first mini P2O5-based moisture monitor, the 'M-i', which is specifically designed for solar-grade gas moisture monitoring.
Problem: High-purity gases can have a direct impact both positively and negatively on solar cell conversion efficiencies. The need to monitor for moisture in the gas delivery system helps prevent gas degradation and contamination, as well as process problems that could impact yield.
Solution: An electrolytic moisture sensor functions by absorbing and electrolyzing all of the water from a controlled flow of sample gas. The resulting electrolysis current is an absolute measure of the amount of moisture entering the detector by Faraday's Law, which states that every water molecule that is electrolyzed produces two electrons in the detector circuit. The M-i moisture monitor is designed for fixed gas applications and does not need to be calibrated against a moisture standard. The M-i measures an ideal range of 500 ppb to 1000 ppm. Utilizing MEECO's electrolytic technology, the new device is palm-sized and provides continuous, no-drift, on-line moisture analysis at a very low cost (under US$2,000).
Applications: Fixed gas applications with a range from 500 ppb to 1000 ppm.
Platform: The M-i moisture monitor is claimed to be the first mini P2O5-based moisture monitor available on the market, offering proven stability, precision and repeatability.
Availability: Currently available.
