high precision co2 sensor

Optical Sensor Technology

PreSens sensors come in many different designs, from robust dipping probes with stainless steel fittings, over small sensor spots, to microsensors with a tip size thinner than a hair. They are extremely versatile and can be applied for precision measurements in micro- as well as in macro-scale. Optical sensors can be easily miniaturized and due to their small size they can even be applied e. g ...
