เครื่องวิเคราะห์ออกซิเจนหน่วยเปอร์เซนต์แบบพกพา หลังจากขยายสัญญาณ, กรอง, ปรับเชิงเส้น, และส่งสัญญาณมาตรฐานจากเซ็นเซอร์แล้ว ไมโครโปรเซสเซอร์จะคำนวณความเข้มข้นของออกซิเจนในส่วนผสมของไนโตรเจน-ออกซิเจน และแสดงผลค่าความเข้มข้นออกซิเจน เครื่องวิเคราะห์นี้มีคุณสมบัติเด่นในด้านความแม่นยำสูง, ความเสถียรที่ดีเยี่ยม และอายุการใช้งานยาวนาน เหมาะสำหรับการวัดความเข้มข้นของออกซิเจนในส่วนผสมของไนโตรเจน-ออกซิเจนในสภาพแวดล้อมต่าง ๆ
GNL-2100L portable high content oxygen analyzer uses 3D ion flow oxygen sensor as measuring unit.After
amplifying,filtering, linearizing correction and standard signal output of sensor signal,the oxygen concentration in nitrogen-oxygen mixture is calculated by microprocessor,and the oxygen concentration display is provided.The analyzer has the characteristics of high precision,good stability and long service life.It is suitable for measuring oxygen concentration in nitrogen-oxygen mixture under various environments.
Applications
It is widely used in air separation industry,such as
pressure swing adsorption (PSA) nitrogen production;
Chemical and smelting industries;
Medical and health industry,such as hyperbaric oxygen
chamber,infant incubator,ventilator,anesthesia machine;
Determination of oxygen concentration in family,ship,
underground command center,tunnel,deep well,civil air
defense engineering,city tunnel,etc.
