Multi-gas Analyzer NMA-230
Multi-gas analyzer NMA-230 is a portable multi-gas detector designed for measurement, analysis, monitoring and control of gas output. Equipped with four gas detector sensors for oxygen, combustibles, hydrogen sulfide and carbon monoxide. Built-in, high-power carbon film with self-priming pump with quick response facilitates easy sampling of gases present at lower atmospheric pressure. The Acrylonitrile – Butadiene- Styrene body shell is dust-proof, explosion-proof and water-proof and durable at low temperatures.
