The Next Generation of Oxygen Detection – Now Lead-Free SI-200E O₂ (Long Life): Eco-Friendly, Durable, Reliable 


Are your customers tired of frequent oxygen sensor replacements every 2–3 years?

Do they operate in high-temperature or remote environments where maintenance costs and downtime matter?


SENKO's SI-200E O₂ (Long Life) brings a game-changing solution to fixed gas detection.


Why Lead-Free?

Traditional electrochemical sensors use lead (Pb), which degrades over time due to oxidation—especially under high heat. This leads to shorter lifespan and frequent maintenance. With SI-200E’s Lead-Free oxygen sensor, we eliminate this issue while aligning with RoHS and global environmental regulations.


Why Buyers Should Pay Attention

- 5+ Years Sensor Life: No more annual replacements—this saves both cost and effort.
- Eco-Conscious Design: RoHS-compliant and lead-free, ideal for customers with ESG mandates.
- Wireless & Magnetic Wand Interface: Configure, calibrate, and diagnose without opening the housing.
- Reliable Operation in Tough Environments: Works flawlessly from –40°C to +60°C with high chemical resistance.
- Self-Diagnostics & Fault Alerts: Built-in diagnostics offer peace of mind in critical installations.


Technical Feature Benefits That Sell Themselves

- Explosion-proof enclosure: Certified for hazardous environments—ensures safety and compliance. 
- 4-digit digital concentration display: Clear and precise monitoring with real-time feedback. 
- Supports 4–20mA (with HART option) and RS-485 output: Ready for full integration into any control system or SCADA network
- Wireless communication supported: Wireless configuration saves time and reduces risk in Ex zones. 
- Enhanced stability through eco-friendly Lead-Free sensor: Greater accuracy and lower drift even in high-stress conditions. 
- Extended sensor life of over 60 months: Reduce replacement frequency and long-term maintenance cost. 


Did you know?

Most lead-based oxygen sensors start degrading at higher temperatures even within the first year. SENKO’s Lead-Free sensors maintain accuracy for over 60 months, even under demanding conditions.
