DELS series Liquid Scintillation Counter is designed for the high sensitive measurements and analysis on low-level alpha and beta radioactivity. The measurement of 3H, 14C and other α/β nuclides can be widely used in nuclear power plants, environmental protection, medical and other industries. We have standard DELS 400S&600S counters and portable DELS 200P&300P counters in availibility so far.
PRODUCT DETAILS
DELS series Liquid Scintillation Counter equipped with automatic sampling vial feeding system up to 200 vials, can utilize the large batch samples measurement with higher testing efficiency and lower costs. The products have a unique shielding design for the low-background lead chamber by integrated casting molding, it minimizes the background against the interference from external environment. Digital signal processing technology and professional application software ensure the accuracy and reliability of the α/β sampling measurement performance.
DELS 400S has dual PMTs using coincidence technology with an external standard γ source, it ensures the accurate measurement on the complex compositions. DELS 600S has triple PMTs using TDCR coincidence technology, without the additional standard source, the measurement and analysis are more convenient and it keeps high detection efficiency.
