Lovibond SpectroDirect เครื่องวัดคุณภาพน้ำ Single-Beam

SpectroDirect เครื่องวัดคุณภาพน้ำแบบ Single-Beam Photometer ใช้แสงจากหลอดฮาโลเจน (halogen lamp) พร้อมด้วยฟังก์ชั่น flash ที่จะยิงแสงเพียงชั่วครู่ในการวัด 1 ครั้ง จึงไม่จำเป็นต้องมีการวอร์มเครื่องแต่อย่างใด SpectroDirect จะทำการทดสอบตัวเองทันทีที่เปิดเครื่อง โดยแสงจะผ่านช่องเสียบตัวอย่างน้ำและเข้าสู่เครื่อง monochromator
