Hot New Products Oxygen Analyzer On Ship - Nernst NP32 portable trace oxygen analyzer – Litong

Application range

The Nernst NP32 portable trace oxygen analyzer is the latest micro-oxygen analyzer designed and manufactured for the microelectronics industry.

The analyzer is used in vacuum welding furnaces, chip manufacturing in the electronics industry, biomedicine industry, bright annealing furnaces for precision parts, high-strength alloy tool coating processing equipment, etc., as well as processes that require oxygen control on various small equipment.The analyzer adopts the long-life, high-precision zirconia sheet structure principle, which can effectively measure micro-oxygen, and the measured micro-oxygen content can reach 10^-30% ~ 100% oxygen content. It is especially suitable for equipment and processes with strict requirements for product process oxygen content control.

The NP32 portable trace oxygen analyzer provides real-time content of O₂% (percentage) of flue gas in the furnace or flue gas and 12 other useful parameters.

The NP32 portable trace oxygen analyzer is also suitable for various other fields that need to measure high-precision oxygen content.
