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.
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 (R2 values 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.
