Wanyi Technology Launches ONETEST-520 Dual-Channel Ion Detector — Redefining Air Quality Measurement Standards

Shenzhen, China — Wanyi Technology proudly announces the launch of the ONETEST-520, a state-of-the-art dual-channel positive and negative ion detector designed to deliver unprecedented accuracy in air quality monitoring. Combining advanced coaxial cylinder electrode technology with intelligent multi-parameter sensing, the ONETEST-520 sets a new benchmark for environmental measurement professionals worldwide.

Why Dual-Channel Matters

Unlike conventional single-channel ion detectors that provide only a vague total ion count, the ONETEST-520 captures positive and negative ion concentrations simultaneously and independently. This dual-channel architecture reveals the true ionic equilibrium state (n⁺/n⁻ ratio) and instantaneous polarity change trends — delivering environmental insights far beyond single-channel capabilities.
