The Toray SD/LD-450 is a zirconia oxygen analyzer with a separate sensor and a thin wall-mount converter, built into vacuum, sealed and inert-gas furnaces and 3D metal printing chambers. The sensor mounts directly in the process, so response is fast, and it reads from 0.001 ppm to 100 % O2.
- Separate zirconia sensor and thin wall-mount converter: flexible installation, little depth
- Direct-insert sensor for very fast response
- Measures 0.001 ppm to 100 vol % O2, 10-20 to 10-0 atm
- Sensor with special coating for durability
- LD-450T: 4-20 mA output and alarm contacts / LD-450C: RS-232C
- CE marking, EN 61010-1, EN 61326-1 and RoHS
The SD sensor type and flange are chosen for your chamber. Request a quote for pricing and availability.
