ECHO 9 Color Options Tab…All these 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’s 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 modelsThis 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.

Comes standard on the ECHO-09DL and ECHO-09DLWThis 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 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 above.

Encoded B-Scan

Software comes standard with the ECHO 9DLW, encoder and hardware upgrades sold separatelyRequires hardware modification to either ECHO 9DLW or ECHO 9DL, uses EZ Scan 4 as a magnetic wheel, linear axis encoder.The EZ Scan 4 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.


Comes standard with the ECHO 9DL and ECHO 9DLWThe ECHO 9 Datalogger stores millions of readings in it’s Datalogger with removable sd card memory 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 9CW and ECHO 9DLWThe 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.

Angle Beam

Sold as a separate software option for our ECHO 9DLWDisplays 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 4 – Magnetic Wheel Encoder

Danatronics EZ Scan 4 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 (No certification is provided with these blocks but can be provide on special order for an additional fee)

Rubber boot

We offer a custom protective rubber booth with built in bail, 4 point chest harness and unique 2 finger hold strap.


Standard 3.7 V Li Ion internally rechargeable battery (16-20 hours) comes standardor optional alkaline tray for 3 AA batteries (8-12 hours)

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.
