Honeywell XNXXSS1SS SO₂ Sensor | 5-20 ppm, Fast Response, Industrial

XNXXSS1SS | Honeywell SO2 Sensor

Product Overview

The Honeywell XNXXSS1SS is a precision electrochemical sensor for low-range sulphur dioxide (SO₂) detection. Specifically, it offers a selectable full scale from 5.0 to 20.0 ppm, with a default 15.0 ppm range. Furthermore, this sensor is designed for industrial safety and environmental monitoring. In addition, it delivers fast response (T90 <30 sec) and outstanding accuracy of ±0.3 ppm. Moreover, its robust housing operates from -40°C to +55°C, ensuring reliable performance in harsh conditions. Consequently, this sensor is an ideal choice for fixed gas detection systems, HVAC, and emission control applications.

Technical Specifications

Installation Guide

First, mount the sensor in a clean, dry area with stable airflow. Then, use the standard 4-pin connector for signal and power. After that, calibrate with certified SO₂ gas (30–70% of range) every 6 months. Meanwhile, the plug-in design enables quick replacement without rewiring. For maintenance, simply wipe the outer housing with a soft cloth. However, avoid direct solvent contact. Additionally, the sensor features automatic zero adjustment and offers easy field calibration via push-button.

Compatibility & Certifications

This sensor is compatible with most fixed gas monitors and controllers. For example, it works seamlessly with Modicon Quantum series. In terms of safety, it meets IEC 61010-1 standards and carries CE mark. Furthermore, the XNXXSS1SS is approved for hazardous areas (ATEX / UL pending).

Typical Applications

Common uses include industrial flue gas analysis and SO₂ scrubber monitoring. Likewise, it suits chemical plant safety, HVAC air quality, and refrigeration leak detection. Moreover, it supports environmental compliance reporting. As a result, its fast T90 response makes it suitable for real-time control loops.
