Imported brand of flame photometer

Imported brand of flame photometerProduct features
The FP640 flame photometer has been greatly improved based on our original product, simplifying the gas system and using liquefied petroleum gas (LPG) as fuel. Equipped with a flameout protection device, greatly improving safety. This instrument has the advantages of small size, simple structure, easy operation, stability and reliability. It has the function of pre-set flame size. The display screen can show decimal points and can be freely adjusted.
