Echo to Echo to ignore Coatings
Comes Standard on the EHC-09, EHC-09DL, EHC-09W and EHC-09DLCW
This option allows for the coating or paint thickness to be ignored. The coating thickness or paint does not make the substrate material any stronger. Without the ability to subtract the paint, the normal measurement would introduce an error of 2 to 2.5 times the thickness of the paint, which represents the sound speed difference from Paint to Steel.

B-Scan
Comes standard on the EHC-09DL and EHC-09DLCW
This option is only available combined with the Data logger option. Provides a non-encoded (time base) or a cross section (side view) of the part being inspected. The image to the right shows the side view of a step block. The image above shows the side view of a step block. The operator can scroll where the cursor line is after a B-scan is generated to get the thickness value as that point (.100") shown to the right.

Data logger
Comes standard with the EHC-09DLC and EHC-09DLCW
The EHC-09 Data logger stores up to 100,000 readings in it´s internal Data logger as linear, 2D, 3D or boiler in alpha numeric or 2600 waveforms (if gage is equipped with waveform option). Thickness values along with the i.d. information and all gage set up parameters are exported to Microsoft excel via the no-charged, included Data XL interface program provided with every Danatronics thickness gage. Our Data logger also interfaces with Ultrapipe. (Data logger: included with all DL gages, also available as an add on for all EHC-09 series).
Live Waveform (A-Scan)
Comes standard with the EHC-09CW and EHC-09DLCW
The live waveform (A-scan) is used to verify reading stability. With the live waveform the operator can adjust gain, range, rectification and 2 forms of blanking to set the gage to ignore unwanted noise or mode converted echoes.
