DrägerSensor Electrochemical Gas Sensor

Models: 6809665 / 6809640 / 6809630 / 6809675 / 6810435 / 6809645 / 6809680 / 6810590

1. Product Overview

The DrägerSensor Electrochemical Series is designed for reliable gas measurement in fixed gas detection systems, including Dräger Polytron series transmitters. These electrochemical sensors are used for continuous monitoring of toxic gases, oxygen, and other hazardous substances in industrial environments.

The models in this listing cover a variety of target gases, including chlorine (Cl₂), hydrogen chloride (HCl), oxygen (O₂), hydrogen peroxide (H₂O₂), hydrogen sulfide (H₂S), ammonia (NH₃), and acidic compounds. Each sensor is gas-specific, so the correct sensor must be selected according to the gas to be detected.

These sensors are suitable for applications in chemical plants, oil and gas facilities, wastewater treatment, industrial manufacturing, laboratories, and other areas requiring continuous gas monitoring.

6810590

For 6810590, I recommend verifying the complete order number from the sensor label before publishing the listing. Dräger's current official sensor catalog lists 6810595 as DrägerSensor Acidic Compounds AC, while the other numbers above can be directly matched to the current Dräger documentation.

4. Product Applications

The DrägerSensor series can be used for:

• Chemical processing plants
• Oil and gas facilities
• Petrochemical plants
• Wastewater treatment
• Industrial manufacturing
