Features
Yokogawa Explosion-proof Zirconia Oxygen Analyzer ZR202S-A-040-S-A-N-E-T-M-E-A
• The built-in heater assembly of the probe can be replaced on site, reducing maintenance costs.
• The probe uses a long-life, high-reliability Zirconia sensor.
• The separate type converter ZR402G incorporates a LCD touch-screen for ease of operation.
• The integrated type ZR202S integrates both probe and converter, to reduce wiring, piping, and installation costs. The ZR202S uses an optical switch for ease of operation at the site.
•Remote maintenance using digital communications
