Min.Order:1 Set
Lixian Instrument Scientific Co., Ltd.
Main Features :
1.The hollow cathode lamp as light source,double light power pulse power supply,One light work, other lamp preheating.
2.The host built-in air pump, to provide a stable, priceless to purify the air as carrier gas
3.Using the optimal 1nm spectral band-width, the light energy is strong, high sensitivity, trouble-free
4.sampling→results→measure the next sample ≤60s
5.Using many kinds of gas liquid separation device like the piston (patent), Can measure various kinds of water samples, suit for measuring turbidity content water samples like sulfide.
It can also measure soil, fertilizer, Marine sedimentary rocks, cement solid samples etc directly.
