Troxler - Model EGauge 4590 -Soil Density Gauge

SHARE

Troxler now offers a license-exempt option for soil quality control testing. The EGauge uses the proven nuclear technology for density measurements unlike other non-licensed density measurement devices. It provides accurate and reliable readings and it is easy to use. The EGauge Model 4590 complies with ASTM D8167. This product is currently available for the US market only.

Exempt from Licensing

Maintaining a radioactive materials license can be complicated and time consuming for owners of Specific Licensed gauges. In the United States, the EGauge is exempt from the radioactive materials license – no special training classes for operators, no TLD badges, no special shipping documents, and no reciprocity needed for use in other states.

Easy to Use

The operation of the Model 4590 is similar to that of the traditional Troxler nuclear density gauges so the experienced operator can use the gauge with little additional training.

Reliable and Repeatable Density Results

Data collected by multiple agencies shows excellent correlation between the EGauge and Troxler’s Model 3440 Density Gauge (R2values ranged from 0.93 to 0.98). EGauge repeatability is also equal to that of the current density gauges as listed in the applicable ASTM specification (0. 3 lb/ft3 (4.8 kg/m3)).

Complete with Moisture Probe

The Troxler Model 6760 Moisture Probe is provided with each EGauge. The electromagnetic probe measures the moisture of the soil in the same prepared hole that is used for the density measurement. Bluetooth technology enables the probe to communicate the moisture data to the EGauge allowing the gauge to display complete results. The EGauge also accepts moisture data using the keypad if another method is used.

Additional Features and Options

  • Easy to Read Display – easy to read enlarged LCD screen with backlighting for viewing in low light conditions
  • Automatic Depth Mode – detects the source rod depth during each measurement
  • Data Storage and Output – stores up to 1000 test readings under multiple projects for later recall or downloading
  • Auto-Store Function – automatically stores sample data under the active project when enabled
  • USB Port – access for outputting stored data to a printer or removable USB storage drive
  • GPS – records GPS information with each measurement and has Wide Area Augmentation System (WAAS) capabilities for better accuracy
“We absolutely love Troxler’s EGauge. It operates much like their nuclear density gauges, but no licensing is required, which we really like. Keep up the good work!”
