LOX-EVB LuminOx Evaluation Interface Board

The LOX-EVB LuminOx Evaluation Interface Board is designed to allow customers to quickly and easily evaluate SST’s range of optical oxygen sensors with the minimum of effort or design work.  

Developed and manufactured by SST, the LuminOx family is a range of factory calibrated oxygen sensors which measure ambient oxygen levels using the principle of fluorescence quenching by oxygen.

The LOX-EVB offers customers the ability to test the LuminOx sensors with ease. The interface similtaneously provides three outputs; RS232 (serial interface voltage levels); RS485 (Modbus RTU) port allows multiple sensors to be addressed on a bus; 0-5V analog output for basic measurements of oxygen only.

The LOX-EVB LuminOx Evaluation Interface Board converts the LuminOx TTL level RS232 output into 3 standard industrial outputs and it auto detects ppO₂ or O₂% variants of LuminOx sensor.
