Pressure Gauge for NPT male 1/4" “A” type

Gauge S0000 시리즈 또는 B0000 시리즈는 모든 가스에 안전하고 편리하게 사용할 수 있도록 개발된 가스 레귤레이터 전용 압력계 시리즈입니다.

특히, 클린(Clean) 질소를 이용하여 캘리브레이션 (Calibration) 하였기 때문에 어떠한 가스를 사용하여도 화학적 반응 없이 안전하게 사용할 수 있습니다.

NPT Male타입의 제품으로, 내부의 모든 부품은 Stainless Steel 304 or 316L and Brass로 이루어져 있습니다. 사용압력은 0 ~ 30psig(약 2bar) ~ 최대 6000psig(약 420bar)까지 사용할 수 있습니다. NPT타입(DRA-S0000) 게이지 시리즈는 조립, 실험의 모든 공정은 크린룸에서 모든 작업이 이루어집니다.

※ DRASTAR’s all pressure regulators are assembled, cleaned, inspected, and packed in clean-room equipped with clean bench, helium detector, particle counter, ultrasonic cleaner, ultrapure water system, vacuum packaging machine, etc. through oxygen cleaning procedure in compliance with process and regulations indicated in CGA 4.1. and or ASTM G-93 and are free of any grease or oils.

    Recommendations


Each product is manufactured since being taken into consideration of the best safety and easy manipulation. However in order to use the regulator in most safe and effective way, you are recommended to use the actual pressure within the range of its 35% ~ 65%. For making precise, smooth movement and to prolong product life, strongly recommended to make a use within above mentioned range.
