Description
SM-EC, Spare Ozone Sensor Board, Precalibrated, 0-20ppm
Suitable for the new ozone instruments OS-4/SM-EC and OS-6/SM-EC.
SM-EC is a pre-calibrated, user-replaceable ozone sensor module that utilizes a state-of-the-art electrochemical (EC) sensing element.
The SM-EC pairs exclusively with instruments with EcoSensor's SM-7 digital interface.
Attention:
Earlier ozone monitor models OS-4 and OS-6, which are still equipped with an interface SM-6, mandatorily need to exchange this with an SM-7/SMEC interface, so that the sensor board SM-EC works at all!
This inexpensive pre-calibrated sensor can easily be exchanged, and thus, one avoids time loss and costs by the shipment of the ozone meter for re-calibration and for the calibration itself.
Simply insert the new sensor board according to the manual - and the instrument is re-calibrated!
