Online CO2 Meter: Carbo 510 Smart Sensor
Our proven online CO2 sensors have taken the next leap in their evolution: The Carbo 510 Smart Sensor has arrived. This sensor delivers values every 15 seconds and is hailed as the fastest CO2 analyzer on the market. It is designed in accordance with the hygiene guidelines of EHEDG (European Hygienic Engineering & Design Group) and provides the highest accuracy and reliability. The sensor`s design also strongly reduces maintenance and service requirements. The Carbo 510 is an intelligent sensor which performs self-diagnosis. It also detects and displays errors and service requirements. In this way the operator is always up to date on the state of the sensor. Carbo 510 is available in three versions: Carbo 510 Smart Sensor combined with an mPDS 5 evaluation unit Carbo 510 Smart Sensor with Operating Terminal (OT) - the measurement values are displayed directly on the instrument, no evaluation unit is required Carbo 510 Smart Sensor with a Remote Operating Terminal (ROT) which can be mounted at a distance of up to 250 meters from the sensor
