ABB TVOC-2-240 High Sensitivity VOC Sensor for Building Automation

Product Overview

The ABB TVOC-2-240 is a high-sensitivity Total Volatile Organic Compound (TVOC) sensor specially designed for building automation and indoor air quality monitoring. It accurately detects low-concentration VOC pollutants, helping create healthy and energy-efficient smart building environments.

Core Advantages

• High Sensitivity & Accurate Detection Optimized for low-concentration VOC scenarios in buildings. Measuring range: 0–100 ppm with accuracy of ±5% of reading. It effectively detects trace VOC emissions from decoration materials and furniture to deliver timely air quality alerts.
• Fast Response for Real-Time Control Response time ≤ 30 seconds. It rapidly captures VOC concentration fluctuations and links with HVAC systems to dynamically adjust fresh air volume, balancing indoor comfort and energy consumption.
• Industrial-Grade Reliability for Building Applications Operating temperature: -20°C to 50°C. Excellent anti-electromagnetic interference performance for complex indoor environments such as offices, shopping malls and hotels. IP20 protection rating for easy installation and maintenance.
• Multiple Outputs for Seamless Integration Supports 4–20 mA analog output and Modbus RTU digital communication. Compatible with building PLC, DDC and IoT platforms to realize data visualization and remote monitoring.
• Low Power Consumption & Maintenance-Free Operation Powered by 24 V DC ±10% with power consumption ≤ 50 mA. Pre-calibrated at factory with minimal long-term drift. No frequent recalibration required, cutting overall building operation costs.
