Product Description

Product Description: ES1-SO2-50 Sulfur Dioxide Gas Sensor

The ES1-SO2-50 is a high-performance, solid polymer electrochemical gas sensor specifically designed for detecting sulfur dioxide (SO2) in various industrial and environmental applications. With a focus on precision, reliability, and cost-effectiveness, this sensor offers a range of advanced features suited for TLV (Threshold Limit Value) monitoring, emission control, and process safety in industries such as petrochemicals, steel, and environmental monitoring.

Key Features:

Amperometric Operation: The ES1-SO2-50 operates on an amperometric principle, utilizing a 3-electrode system for precise and reliable detection of sulfur dioxide gas.
Fast Response: The sensor delivers a rapid response time, ensuring that gas concentrations are measured promptly, with a T50 (time to 50% of the final value) of less than 20 seconds and T90 (time to 90%) of less than 60 seconds.
Linear Sensitivity: The sensor features an extreme linear response, maintaining high accuracy even at higher concentrations of SO2, making it ideal for use in environments with fluctuating gas levels.
Low Power Consumption: The device operates with low power requirements, making it suitable for battery-operated systems and applications where energy efficiency is critical.
Individually Calibrated: Each sensor is factory-calibrated and comes with an individual test report, ensuring high accuracy and reliability in every unit.
Long Service Life: With an expected lifetime of over 3 years in air, the ES1-SO2-50 offers long-term reliability. Its low long-term drift of less than 1% per month further enhances the consistency of its readings.
Wide Operating Conditions: Designed to function effectively across a broad range of environmental conditions, the ES1-SO2-50 can operate in temperatures from -40°C to +55°C, with a humidity range of 15-95% RH (non-condensing) and a pressure range of 800 to 1200 hPa.
