SERVOTOUGH Oxy 1900

Key Features

Reliable and Robust: Built on Servomex’s robust and field-proven paramagnetic sensor technology, ensuring high accuracy and stability.
Hazardous Area Approved: Certified for hazardous areas with ATEX Cat 2, IECEx Zone 1, and North American Div 1 and Zone 1 approvals (applied for).
Heated Sample Compartment: Eliminates condensation issues for samples with a dewpoint up to 50°C (122°F), significantly simplifying sample system requirements.
Internal Flow Sensor: Provides peace of mind, improved safety, and facilitates preventative maintenance by continuously monitoring sample flow.
Internal Pressure Compensation: Automatically compensates for pressure variations caused by barometric or vent pressure fluctuations (e.g., flare stacks).
Autovalidation: Reduces the need for hands-on maintenance through remote or local validation, ensuring the highest levels of confidence and measurement availability.
Low Cost of Ownership: Requires no measurement reference gases or purge gases for certification or flammable samples, leading to long calibration intervals and cell life.
Functional Safety: SIL 2 Hardware Compliance, with a functional safety manual available.
Flexible Outputs: Offers a variety of output options including 4-20mA, alarm relays, and Modbus RTU/Modbus TCP (Ethernet).
