O2-A2 O2-A3 4OX-V 7OX-V S+4OX SGX-4OX Gas Oxygen Sensor Electrochemical Gas Sensor High-performance Leak-free O2 Sensor For Oxygen Gas Analyzer
Key Features and Benefits:
• False alarm immunity
• Reliably meets stated life
• Superior environmental performance
• Enhanced response time in extreme applications
IMPORTANT NOTES:
Obstruction of the vent hole will compromise
performance, and must be avoided. Do not remove label.
Adequate free volume should be provided below the
sensor to ensure full performance.
All tolerances ±0.15 mm unless otherwise stated.
DO NOT solder to pins.
All performance data is based on conditions at 20ºC,
50% RH and 1013 mbar.
