Mass Flow Meters (LCD Touch Screen)	Six precision mass flow meters : MFC Accuracy is: ±1.5% F.S. MFC 1 for Ar : Gas flow range depends on customer’s requirement MFC 2 for N2 : Gas flow range depends on customer’s requirement MFC 3 for O2 : Gas flow range depends on customer’s requirement MFC 4 for C2H2: Gas flow range depends on customer’s requirement MFC 5 for CH4: Gas flow range depends on customer’s requirement MFC 6 for H2: Gas flow range depends on customer’s requirement (above flow range is only for reference, Pls confirm gas flow range before palce order. ) One gas mixing tank is installed on bottom case with 6 stainless steel needle valves is installed on left side of bottom case to control 6 type gases mixing manually. LCD Touch Screen (designed by kejia, with Kejia Logo) for MFC is as below:
(this valve is not supplied by us)ALD valve	Two ALD valves with pulse controller (min 10 ms duration ) And connect to touch screen
Liquid-Vapor Generator	Automatic liquid vapor generator is included and connect to ALD valve
1.7MHZ ultrasonic Atomization	Equipped with a 1.7MHz ultrasonic atomizer, the liquid can be atomized into liquid particles and introduced into a tube furnace. 20VAC, 1.7MHz ultrasonic atomizer • The liquid tank comes standard with 316 stainless steel,and sealed with a fluorine rubber seal; • Atomization amount can be set from 1 to 8, and the amount of atomization can be controlled by adjusting the size of the gear; • It can realize two functions of continuous operation atomization and regular operation atomization. The timing can be adjusted from 30 minutes to 180 minutes (adjust the gear every 30 minutes).
Liquid injection system	• A standard set of liquid injection pumps for automatic liquid feeding • The syringe pump is equipped with a plastic syringe with a maximum volume of 60ml for holding liquids; • Syringe pump speed adjustment range: 0.004ml / min—70ml / min
Water Chiller	Used to cool down water cooled flange and vacuum pump.

Pls note: C2H2 CH4 and H2 are flammable gas,suggest customer to operate system in ventilation environment,and it is better to prepare gas alarm equipment at customer side.
