Software Options

All ECHO 9 Options are field upgradeable via the keypad. Danatronics offers a unique and convenient way to upgrade your gages. The upgrades are done directly from your gage and do not require the use of a computer. The advantages of field upgradability are:
  • Never worry about downtime
  • No extra shipping cost
  • Less cost of ownership due to less freight and duty
  • No need to worry about the product being obsolete
  • Simple and Fast to perform

The Field upgradeable options for the ECHO 9 series are:
Echo to Echo to ignore Coatings
Comes Standard on all ECHO 9 Color models 

This option allows for the coating or paint thickness to be ignored. The coating thickness or paint does not add any structural integrity to the base material. 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. In addition it is expensive and time consuming to grind out the coating thickness and to re-apply a coating. 
Comes standard on the ECHO-09DL and ECHO-09DLW

This option is only available combined with the Datalogger option. Provides a non-encoded (time base) or a cross section (side view) of the part being inspected. The A-scan and B-scan can now be view at the same time. The operator can scroll where the cursor line is after a B-scan is generated.
Encoded B-Scan
Software comes standard with the ECHO 9DL and ECHO 9DLW, encoder and hardware upgrades sold separately 

Requires hardware modification to either ECHO 9DLW or ECHO 9DL, uses EZ Scan 6 as a magnetic wheel, linear axis encoder.

The EZ Scan 6 combined with our ECHO 9DLW is the ultimate in easy to use, affordable magnetic wheel linear axis encoder for B-scan surveys with reports. The EZ Scan 4 sends a pulse to the gage to take a thickness reading while drawing the B-scan image based on one axis. The gage keeps track of the distance traveled (DT) so you can cross reference any wall thinning areas to the image displayed and saved into memory. To show A-scans and B-scans on the computer, you must purchase separately our Data XL Pro.
Available as an optional upgrade for all ECHO series gages.    The bluetooth software option also requires internal hardware modification on the PCB (does not affect other specs, IP rating or require additional power source).

Allows ECHO to export data such as thickness readings or files to another device via internal bluetooth.  DataXL mobile can be used to facilitate the transfer of information on IOS and Andriod phones and tablets.  DataXL Mobile is coming soon in the Apple store and Google Play Store.
Comes standard with the ECHO 9DL and ECHO 9DLW

The ECHO 9 Datalogger stores millions of readings to its removable sd card as linear, 2D, 3D or boiler in alpha numeric or thousands of 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 Datalogger also interfaces with Ultrapipe. Please contact Danatronics for more details.
Live Waveform
Comes standard with the ECHO 9W and ECHO 9DLW

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.
Oxide Scale
Sold as a separte software option after upgrade to an ECHO 7 or 8 with waveform

When equipped with the oxide scale option and 20mhz delay line transducer, both ECHO 7 and ECHO 8 units with live waveform can measure the oxide scale (0.015"-0.040") and tube thickness calibrated to their independent sound speeds.
Angle Beam
Sold as a separate software option for our ECHO 9DLW

Displays trig functions for angular distance, surface and depth. Can use 2.25MHz, or 5 Mhz, in angles from 30-80 degrees. NOT TO BE USED AS A FLAW DETECTOR due to limited scan speed and vertical linearity requirements of most flaw detectors.


The following accessories are available for the ECHO 9 series
EZ Scan 6 - Magnetic Wheel Encoder
Danatronics EZ Scan 6 encoder is a 1 axis encoder that keeps track of the transducer movement as it relates to the B-scan image. The ECHO 9 must contain the Datalogger Software for the B-scan to appear. This feature requires a hardware change to allow for the lemo encoder jack on the top of the gage.
Spring Loaded Holder
The spring loaded holder (SPH-718) is the ideal fixture to be used on small diameter applications such as tubing to prevent the probe from rocking. Shown above is the SPH-718 with the DK718 transducer inside. The probe can be rotated as well and the fixture has v-notches to assist in probe alignment.
Chest harness
Custom 4 point chest harness with comfortable adjustment of straps for shoulder and waste line. Comes with metal detents
Magnetic Pipe Holder
Available magnetic pipe holder that screws onto the ¼, 20 connector on the ECHO 9. This is ideal to stabilizing the ECHO 9 on a larger pipe or any magnetic surface and can even be used up side down.
5 Step Test Block
We offer a 5 step test block, made of carbon steel with nickel plating engraved in both English and Metric values from .100’, .200”, .300”, .400”, .500” or 2.54mm, 5.05mm, 7.5mm, 10.0mm, 12.7mm 
Rubber boot
We offer a custom protective rubber booth with built in bail, 4 point chest harness and unique 2 finger hold strap.
Heavy Duty Bail
Heavy Duty bail for use with rubber boot 
Standard 3.7 V Li Ion internally rechargeable battery  comes standardor optional alkaline tray for 3 AA batteries
ECHO 9 Transport Case
The EHC-09 Transport Case is shown with common inclusions. (Spare batteries and 5 step test block sold separately).
Dual and single cables offered in 6 feet or other lengths upon special order. Shown left to right: DLM-06, DLM-06ACMP, LM-06
We offer a variety of ultrasonic couplants from a standard gel in 2 Oz. or 12 Oz. options, to high temperature up to 1100 Degrees F. Contact us for more details.
AC Power
ECHO 9 series comes with a convenient AC charger via the USB port so you do not have to replace the batteries on a regular basis.
With this hardware option the operator can use a footswitch to save, freeze or send readings.
