4520TF-type atomic absorption spectrophotometer Caution:

The work of planting AA4520TF equipment room are not allowed to have open flame� acetylene cylinders and equipment shall not be the same in a room

Acetylene cylinders must be placed well-ventilated room� the room shall not have open fires.

Ignition device� the acetylene flow rate can not exceed 3L/min� and waste water pipes before ignition to ensure there is water-sealed

Acetylene cylinder output pressure can not be more than 0.12 MPa

Ignition device� the operator can not be away from the apparatus

Flame� they would first off acetylene cylinders until the flame goes out� and then flame atomizer parameters of the workstation-based "test" button� until the pipe more than acetylene gas venting

Users who need to do a nitrous oxide acetylene� must be certified by my company technician training to use.

4510GF (graphite furnace) boot� you need to pass high-power 220V power supply and water� gas� for safety� the operator can not turn away from the apparatus after the
