เซนเซอร์วัดความชื้นที่มาพร้อมกับอุปกรณ์ประกอบที่จำเป็นต่างๆในการวัด ให้การปรับสภาวะแก๊สที่จะวัด ง่ายขึ้น และการวัดถูกต้องแม่นยำขึ้น
To get the best possible performance from your MDM300 or MDM300 I.S., it is crucial to have appropriate sample conditioning for your measurement point. Options are available to cover all common sampling requirements – from verification of dry compressed air supplies, to the measurement of natural gas downstream of a glycol contactor.
