Example: AD 9 - 0000 - B 4M Notes: Sensortechnics is asking customers for a sample of their tubing. The sensor will then be calibrated for exactly this tubing. For proper function the sensor should only be used with the tubing which was sent to Sensortechnics! Custom specific modifications are widely available.
