Portable Hydrogen Purity analyzers VHP-200 is an intelligent gas analyzer for gas measuring based on the measurement of thermal conductivity of the ambient gas. To compensate for the influence of temperature and humidity, these are measured separately and a correction is made for them in the microcontroller. Each device is factory calibrated.

PortableTri gas analyzers are microprocessor–controlled instruments with sophisticated software processes that meet the needs of industry in analyzing Gas with accuracy and reliability. Hydrogen Purity gas analyzers in India TCD transducer provide highly stable and reliable results. We are supplying this hydrogen purity analyzer India-wise.

The Vasthi Portable hydrogen purity analyzer Model VHP -200 with digital readouts and alarms is a direct reading compact portable hydrogen purity analyzer, designed to serve the demanding field requirements of the Hydrogen producing and using industry. It is designed to replace the cumbersome and time-consuming set apparatus and provide a quick and accurate reading of Hydrogen Purity. It offers the user a distinct advantage in terms of economy, dependability, maintenance, and ease of operation. The instrument incorporates a detector as a transducer. It has adjustable, visual, and audible alarms at WARN & ALARM levels. The instrument is simple and easy to operate. Just switch it on, and adjust zero control so that indicator shows the reading.
