ATO fixed VOC gas detectors are designed for continuous monitoring, offering reliable performance and durability in harsh industrial conditions. They are typically installed at reliable locations to monitor and detect VOC leaks or emissions.
Features
- VOC gas detector adopts high precision sensor for accurate gas leak detection.
- Volatile Organic Compounds gas detector is equipped with 3-wire system 4-20mA analog output, relay output, RS485 output (optional).
- The VOC gas monitor is compatible with various controlled alarms, PLC, DCS and other control system, and can be remote monitored.
- Explosion-proof design, fast, relaible and stable.
- Infrared ray controller can remote control the alarm point settings, zero calibration, and address modification.
- Two-stage alarm with sound and light, and the alarm point is settable.
- The VOC gas detector has self-calibration function, and three standard keys will be used to realize on-site maintenance.
- Volatile Organic Compounds gas detector can output one or two on-off signals, can drive ventilator, solenoid valve or other external devices.

Tips: What are VOC gases?
Volatile Organic Compounds (VOCs) are gases released from various solids or liquids and are commonly found in household products, building materials, and industrial processes. These compounds evaporate easily at room temperature, releasing the molecules into the air. Common sources of VOCs include paints, solvents, cleaners, and fuels. While many VOCs are harmless, some may pose health risks, causing indoor and outdoor air pollution. Short-term exposure to high concentrations of VOCs may irritate the eyes, nose, and throat, as well as headaches and nausea. Long-term exposure to certain volatile organic compounds can lead to more serious health problems, such as liver, kidney, and nervous system damage, as well as an increased risk of cancer. Therefore, in this environment, it is very necessary to choose to use a VOC gas detector.
