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. Please contact your nearest
Sensortechnics sales office for further information.
Sensortechnics reserves the right to make changes to any products herein. Sensortechnics does not assume any liability arising out of the
