Product Code: AS2100
application
The single flame atomic absorption spectrophotometer AS2100 is a brand new product carefully built by Optosky. The flame sensor identifies the flame by sampling the flame temperature, eliminating the interference of external light on the sensor, and improving the reliability of flame identification; computer control completes automatic ignition. It ensures that ignition can only be carried out when safety conditions are met; when the flame is extinguished abnormally, it will automatically alarm and cut off the gas; the electronic gas circuit control of the flame gas flow will automatically alarm when the gas circuit pressure is insufficient.
AS2100 is compact in design and easy to operate. It provides safe, reliable and durable analysis methods for routine laboratory analysis, production process control and experimental teaching. It has excellent performance, accurate indicators and stable performance. It can meet many common needs and is deeply favored by users. favorite.
It is widely used in quantitative analysis of elements in rare earth analysis, precious metal analysis, environmental protection, water quality testing, alloy materials, building materials, medical and health, universities and other scientific fields.
