Caution…
Before using new insertion tubes for calibration in the ETC-
125 instrument, the insertion tubes must be heated up to
maximum temperature 125°C (257°F) for a period of
minimum 30 minutes.
Insertion tubes are only available for the ETC-125 A.
An insertion tube is selected on the basis of the diameter of the
sensor to be calibrated. You may choose between an 8 mm / 5/16
inch insertion tube, an 3/8 inch insertion tube or alternatively, you
may order an undrilled insertion tube and drill the required hole
yourself. The finished dimension should be as follows:
•
Sensor di0.2
+0.05/-0
mm.
A bore is selected on the basis of the diameter of the sensor to be
calibrated. The sensor can now be inserted directly into the bore of
the well. See Fig. 2 for various design combinations.
