Choice of of digital RMS Probes


The CCA-S-20X is an analog probe with NDIR technology for measurement of carbon dioxide (CO2) for incubators. Developed with a pyroelectric infrared detector with dual temperature compensation and an integrated semiconductor temperature sensor to maximize accuracy and minimize drift. The signal is converted to 4...20 mA by the converter with power supply (CCA-S-20X-SET).
