It is used as an entrance and exit concentration monitor for VOC treatment equipment, etc.!
The "VM-500 Series" is an intermittent continuous monitoring device that samples the target gas to measure VOCs. It is equipped with an automatic control function for zero-point calibration air, enabling reproducible long-term monitoring measurements. Additionally, we also offer the wall-mounted simple VOC monitor "VM-604," which inherits the basic performance of the handheld VOC sensor. 【Features】 ■ Wide detection range / with analog output / with two-stage alarm contacts ■ Capable of intermittent continuous operation / maximum memory of 1,000 points ■ Automatic control function for zero-point calibration air ■ Capable of reproducible long-term monitoring measurements ■ ETV verified model (VM-501) *For more details, please refer to the PDF materials or feel free to contact us.

Company information
Our products and technologies consist of innovative portable sensors that are simple and low-cost, developed based on licensed technology from Hecht GmbH, utilizing proprietary high polymer thin films and the Interference Enhanced Reflection method (IER method). The sensor film has a reversible response, excellent repeatability, and a long lifespan, while the sensor element is chip-based, making mass production and element replacement easy. The fiber-optic design allows for safe detection even in hazardous areas. Additionally, a stationary device can be configured for online monitoring, enabling continuous automatic monitoring, which can be used for primary screening in traditional sampling and laboratory analysis methods (such as gas chromatography and fluorescence analysis).
