经济型火焰光度计

仪器简介：
Use this economical flame photometer for routine determinations 
of sodium and potassium in industrial and educational applications.
 This easy-to-maintain unit gives you fast and accurate results. 
An automatic gas shutoff mechanism activates if the flame becomes 
accidentally extinguished, ensuring your safety. 
Unit comes with one each of Na+ and K+ filters, two meters each of 
gas and air tubing, and necessary fittings. Order optional lithium, 
calcium, and barium filters separately. Note: Filters are factory 
fitted, please specify at time of ordering.
