1. Product Overview
The Induskey SGA-ZHB-6 is a six-channel signal conversion board developed specifically for air quality monitoring, pollution source online monitoring, and odor online monitoring. According to customer requirements, the board accepts 1 to 6 smart gas sensor modules for different gases and outputs all channel signals uniformly over RS485, RS232, or USB-to-TTL serial interfaces — with no restriction on measuring range or sampling method.
Through the inserted sensor modules, the board is compatible with electrochemical, catalytic, infrared, PID (photoionization), and semiconductor sensing principles, supporting more than 1,000 combustible, toxic, and volatile gases. Built-in imported original sensors deliver high accuracy and stability and sensitively capture PPB-level gas concentrations; diffusion or pump-suction sampling can be selected to match the monitoring scenario.
Built on an intrinsically safe circuit with patented technology, algorithms, and design, the board is embedded into online monitoring instruments and stations. All sensor modules share a unified size, unified pin positioning, and a unified usage method, so gas configurations can be changed without redesign — solving rapid integration and fast productization of multi-gas monitoring equipment for OEM customers. Free commissioning tools and an open communication protocol further simplify secondary development.
