Vacuum deposition Model SD/LD-450

Oxygen AnalyzersFor Vacuum Deposition, Sealed Furnaces, and Gloveboxes

SD/LD-450
Model: SD/LD-450


Flexible setup layout. The oxygen sensor and low-profile converter are separated, greatly relaxing limitations on where the device can be installed.
Space saving. The newly developed low-profile wall mounted converter eliminates concerns about the device’s depth.
Ultra-high-speed response. The separated sensor provides the fastest response speed.
Highly durable sensor. A special coating is used for even greater durability.
Compliant standards. Compliant with CE marking, EN61010-1, EN61326-1, and RoHS. Sputtering systems, equipment gas purity management, factory pipe Ar weld management, experimental equipment, and testing equipment
Sensors are compatible with NW flanges (16, 25, 40) for vacuum and screw-in units (3/8R).Select the appropriate type for use condition.
Installation example (SD sensor and LD-450 converter work in pairs.)
