Evident 72DL PLUS Thickness Gauge Repair
The 72DL PLUS is the precision end of the Evident thickness range, driving single-element transducers up to 125 MHz on the high-frequency model to measure material as thin as 0.0127 mm and to display up to six individual layers at once in multilayer paint and coatings. It runs measurement rates to 2 kHz with a 60 Hz display update behind a 7 in. WVGA touchscreen, in an IP65 body. Working at those frequencies is what makes it capable and what makes it unforgiving: signal quality a corrosion gauge would shrug off is the difference between resolving six layers and resolving one.
June Company’s certified technicians repair the 72DL PLUS for automotive and aerospace coating inspectors, multilayer paint analysts, precision manufacturers, and QA laboratories. We diagnose and repair at the board and component level, and every instrument is functionally verified against calibrated reference blocks before it ships back.
Common 72DL PLUS problems we fix
- High-frequency pulser-receiver faults — loss of bandwidth or rising noise, which costs layer resolution before it costs a reading.
- Probe, connector and cable faults — intermittent or dead channels that trace back to worn connectors rather than the probe itself.
- Multilayer measurement faults — layers that used to separate cleanly no longer resolving against the same standard.
- Display and touchscreen failures — dim, dead or unresponsive panels, including digitizer faults that make the interface unusable in the field.
- Battery, charging and power faults — shortened runtime, or shutdowns partway through a shift.
- USB, Wi-Fi and Bluetooth communication faults — results not transferring to the host software, or the instrument not being recognized at all.
- Housing, seal and ruggedization damage — cracked enclosures and failed gaskets after a drop, which let dust and moisture inside the instrument.
- Calibration and velocity-table faults — the gauge not calibrating reliably against reference standards.
- Data logging and export faults — readings not storing or not transferring to the reporting software.
- Keypad and interface wear — controls becoming unreliable in production use.
FAQs
We have lost layer resolution on paint. Is that the probe or the gauge? Either can cause it. We test the instrument against a known-good transducer and reference standards, which separates the two definitively.
Can you verify performance on our specific layer standards? Send them with the instrument and we will. Verification against the standards you actually work to is far more useful than a generic check.
Do you service the older 72DL and 38DL PLUS? Yes, the precision and corrosion gauge lines both come through.
