Multifunctional Gas Detector

The VP200 is a handheld, high-sensitivity, flammable, and toxic gas detector that can detect trace levels (ppb) of various chemical gases, including volatile organic compounds (VOCs), and sound alarms when concentrations exceed threshold levels. The device features two composite detection modes: diffusive and pump-suction, with the flexibility to switch between them. The diffusive mode can be used independently, making it compact, portable, and wearable.

Utilizing photoionization detection technology, the device offers advantages such as a wide detection range, rapid response, and stable and reliable performance.

The VP200 can detect over 200 types of volatile organic compounds, including aromatic hydrocarbons, aliphatic hydrocarbons, ketones, esters, alcohols, and more. Additionally, it can trigger alarms for certain inorganic toxic gases such as ammonia, phosphine, arsine, hydrogen sulfide, among others.
