In order to ensure that the fruit comes out of the transportation and storage periods in good condition, they are preserved in a protective atmosphere. The degree of ripeness and growth can be selectively influenced by means of a defined temperature and through controlled concentrations of carbon dioxide (CO2), oxygen (O2) and ethylene (C2H4). Reliable and accurate gas sensors are necessary for the monitoring of the correct concentrations. This is where the Premium 4 EVO Infrared Sensors come in. 

Infrared gas sensor for process control and gas analysing using dual wavelength technology are designed for different applications in a wide range of gas measurement systems including fruit ripening. The PREMIUM4 EVO sensor is easy to be integrated into OEM systems, where long term stability, repeatability and reliable performance are required. A wide supply voltage range, Modbus ASCII or RTU data communication, current and voltage interfaces (optional with Namur NE43) offer a variety of options to connect the PREMIUM4 EVO sensor.

Atmospheric pressure compensation, on board status LED, temperature compensation, low drift, ready to use calibration, a wide range of different gases and measurement ranges - all that makes the smartGAS PREMIUM4 EVO sensor the best choice also for your application and helps to save time and costs with design in.
