Continuous PM10 & PM 2.5 Monitoring Analyzer: Vasthi Instruments VDPM – 6000, Real – Time Portable Beta Attenuation Mass Monitor, continuously measures the mass concentration of ambient particulate matter collected onto glass filter tape with time resolu-tion of one-minute. The VDPM-6000 employs an in-line sampling geometry in which the attenuation of beta rays across filter media is measured and particulate matter is sampled simultaneously. This allows ambient sampling to occur for virtually 60 minutes each hour. It also allows for beta ray measurements to be made for virtually the entire hour thereby improving sensitivity and time resolution. http://www.vasthi.com/continuous-pm10-pm-2-5-monitoring-analyzer/ VDPM – 6000 employs a unique “in-situ” sampling technique where the beta measurement is kept at a near fixed temperature above ambient conditions, thereby minimizing measuremen...

Ambient Carbon Monoxide Analyzer  Carbon monoxide Analyzer uses non-dispersive infrared gas filter correlation technology, combined with the most advanced microprocessor technology provides accurate, reliable Co ppm level detected, suitable for application of atmospheric monitoring requirements. Working principle non-dispersive infrared gas Analyzer carbon monoxide filter correlation technology. CO molecules on the specific laws of infrared optical absorption in accordance with Beer-Lambert. Comparison of infrared energy in the sample and reference gas absorption http://www.vasthi.com/ambient-carbon-monoxide-analyzer/ . Concentrations of CO can be obtained. Full control over all the functions of this instrument at the same time, can also provide important operating parameters of online instruction. During the measurement, real-time automatic compensation of the temperature and pressure changes.

Portable syngas analyzer Vasthi uses heated probe to collect the sample from the sample line, it will maintain constant temperature and removes the dust and mist from the sample gas. http://www.vasthi.com/portable-syngas-analyzer This gas sample passes through electrically heated tube to cooler. It will remove the vapour content and cools the gas sample to 5ᵒC dew point range and this sample gas goes through the filter that eliminates the dust particle remaining and finally sensor senses and gives the exact readings in syngas analyzer. Gasification is a technological process that can convert any carbonaceous (organic) raw material such as coal into fuel gas, also known as synthesis gas in short syngas. Generally a high temperature/pressure vessel where oxygen or air and steam are directly contacted with the coal or other feedstocks like coal, biomass, and some waste material causing a series of chemical reactions to occur that convert the feed to electricity, syngas and...
