The pump-suction type handheld VOC Monitor is a detection and alarm instrument for continuously monitoring the concentration of VOCs (volatile organic compounds). It can also be equipped with temperature and humidity measurement. It allows for convenient and rapid mobile detection of VOC concentrations in the air.
Suitable for detecting volatile organic compounds (VOCs) during the production and use of cleaning solvents, adhesives, coatings, paints, glues, organic solvents, inks, etc. When the detected VOC concentration reaches or exceeds the instrument’s preset alarm concentration value, the handheld VOC Monitor will emit an audible and visual alarm, vibrate, and display an alarm screen to alert the operator.

Key Applications of Handheld VOC Monitor
- Handheld VOC monitors can quickly and in real-time detect VOC concentrations in the production environment, ensuring companies can immediately monitor VOC emissions during production.
- Through real-time monitoring, companies can promptly detect and control leaks of hazardous chemicals, preventing VOC concentrations from exceeding limits, thereby protecting the environment and employee health.
- In industries such as chemicals, paints, and coatings, VOC emissions are subject to strict environmental regulations. Handheld VOC monitors help companies ensure that VOC emissions during production comply with national and local environmental standards, avoiding environmental violations.
- By regularly monitoring VOC concentrations in production facilities and workshops using a handheld VOC monitor, companies can understand the environmental performance of their production processes, further optimize process parameters, and reduce VOC emissions.
- VOCs pose a potential threat to employee health. Handheld VOC monitors can detect VOC concentrations in the workplace, ensuring employees work in a safe environment and preventing occupational diseases.
- In emergencies such as VOC leaks, handheld VOC detectors can quickly locate the leak source, providing crucial information for emergency response and ensuring employee safety.
- Handheld VOC detectors typically have data logging capabilities, automatically recording detection data to support subsequent environmental audits and process improvements.
