    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.

    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! 

    Technical data:
    Mesasuring range: 0.03-20ppm (1-50ppm upon request only for OS-6/SM-EC)
    Resolution: 0.01ppm
    Accuracy: ±20% of reading or ±0.01ppm, whichever is greater
    Response time: <60s
    Measurement rate: 1s
    Temperature compensation: Yes
    Recommended temperature range: +10 to +30°C
    Recommended humidity range: 30 to 60% RH
    Warm-up time: 1 hour before testing; for best results allow 10 hours before continued use.
