O2 PPM BOARD

The O2 PPM BOARD ensures precise and stable O₂ measurements in the PPM range, up to 1000ppm, thanks to unique electrochemical sensors. The board supports two sensor options: one for 0-10ppm and another for 0-500ppm, both with overload up to 1000ppm. It offers a wide range of output options, including Modbus TCP-IP, RS485, and 4-20mA analog connecton, ensuring seamless integration. With its excellent cost-performance ratio, our solution stands out as a highly competitive alternative in the market.

Key features

PPM LEVEL
The specific and unique electrochemical sensors guarantee a precise and stable measurement of O2 values in the PPM range, from 0 up to 1000ppm.

TWO DIFFERENT SENSORS
You can combine the board with two different sensors: one with an optimal range of 0 to 10ppm and another covering 0 to 500ppm. Both sensors ensure overload up to 1000ppm.

WIDE OUTPUT RANGE
The board can be supplied with various outputs, both digital and analogue including Modbus TCP-IP, RS485 and 4-20mA.

COMPETITIVE PRICE
Our solution provides a cost-performance ratio that offers a significant advantage over other market alternatives.
