PAFS-6806/801
TOP
The PAFS-6806/801 reduces the excitation angle between the light source and PMT based on the original model, which not only increases the received fluorescence signal intensity but also reduces background interference to improve instrument sensitivity. The instrument adopts a semi transparent and corrosion-resistant ABS magnetic structure for the front door, avoiding external air interference and allowing online observation of chemical reactions during the testing process. The circuit also adds a split signal control module, which ensures no inter channel interference even when there is a large difference in the concentration of the two elements measured in the sample during dual channel simultaneous measurement. Specially suitable for testing departments with large sample sizes and simultaneous dual channel measurements, the innovative software and hardware design ensures the accuracy, safety, and ease of use of sample analysis, and the instrument maintenance is simple and convenient.
