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.)
