Danatronics most popular thickness gages are those in our EHC-09 series. With thousands of units in the field, our durable, custom molded case with raise rubber keypad is IP54 rated and has proven it can handle your toughest jobs (this is bad help fix). The EHC-09 series is available in 6 models to suit every budget and application. What’s best is our simple upgrade path where all gages are capable of quickly and easily (directly from the keypad) adding any software options. Features include a graphic display with multiple languages, vibrate on alarm, fast minimum, echo to echo to ignore coatings, 100K reading Datalogger with export to excel, B-scan and live A-scan with waveform adjust.


Our EHC-09 series is our most popular series. The EHC-09 is available in 6 models ranging from our most basic EHC-09A to our loaded EHC-09DLW. See options tab for more details and individual software options.

The EHC-09A is our entry level, field upgradeable gage in our EHC-09 series. It can be used with three transducers. The standard and default transducer is our DKS-537 which measures from .040-20” in steel the DC-250 is the preferred probe for more attenuating materials such as castings and the DK-718 for thinner (.030” in steel) or smaller diameter applications such as boiler tubes. Our EHC-09 series gages come standard with a carrying case, 2oz bottle of couplant, CD manual and DKS-537 transducer. (shown right: Standard kit inclusions. Test block and batteries sold separately)
The EHC-09B model includes all the features of the EHC-09A as well as the full fleet of offered probes for the EHC-09 family. The EHC-09B also includes an alarm that beeps on alarm conditions.
The EHC-09 includes all the features of the EHC-09B model. The EHC-09 also includes echo to echo to ignore coatings, vibrate on alarm, and fast minimum. Vibrate on alarm informs the user when a thickness is above or below a preset threshold by causing the gage to vibrate, making it ideal for loud working environments. Fast Minimum can make 20 readings per second as well as hold on to the minimum reading while simultaneously displaying the actual reading, gain adjust in low, standard and high in 3dB settings, velocity mode to use the gage as a velocimeter as well as hold and differential modes.
The EHC-09DL model includes all the features of the EHC-09 as well as a 100,000 reading Datalogger with the ability to export readings to excel. It also includes the ability to view B-Scans as well. The EHC-09DL kit comes with a USB cable and a protective pouch.
The EHC-09W combines a live waveform with all of the features of the EHC-09 gage (no datalogger). Additionally, it can adjust range, gain, blanks, and rectification.

This is our top-of-the-line model containing all the features of the EHC-09DL and the EHC-09DLW. It includes Echo to Echo, Bscan, a 100,000 reading Datalogger (36,000 waveforms) and a live waveform.

Software Options

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. Most competitors do not offer field upgradability. 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 upgradable options for the EHC-09 series are
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. (shown right: EHC-09 reading the .500 step of a test block while ignoring the card/coating)
Comes Standard on the EHC-09DL and EHC-09DLCW

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 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.
Comes Standard on the EHC-09DL and EHC-09DLCW

The EHC-09 Datalogger stores up to 100,000 readings in it’s internal Datalogger 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 Datalogger also interfaces with Ultrapipe. Please contact Danatronics for more details. (Datalgger: included with all DL gages, also available as an add on for all EHC-09 series).
Live Waveform
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.


The following accessories are available for the EHC-09 series

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.
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)
Protective Pouch
We offer a custom protective pouch Part Number PP-09 for the EHC-09 Series.
EHC-09 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
This Dual lemo to microdot adapter is required when using a delay line or pencil probe with our EHC-09 series.
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.
With this hardware option the operator can use a footswitch to save, freeze or send readings.
AC Power
With this hardware upgrade, the EHC-09 can be used with AC Power (please note, this is not a re-charging system). In other words, with this option, the EHC-09 can be either used with AC or battery mode.


Danatronics offers a wide variety of dual transducers from .5-10 Mhz, high temperature duals and delay lines including pencil probes (12 Mhz.) for special applications. Consult Danatronics or one of our authorized representative for the proper use and recommendation for your application. Molded plugs are available upon request for an additional fee (if they are not already included with the probe). Transducer certifications may also be available for an additional fee.
