The DELTA Classic Plus with a 40kV tube and Si-PIN detector is ideal for simple applications. The DELTA Classic Plus provides quick ID, screening, sorting, and elemental and metals analysis. The DELTA Classic Plus is a proven, ruggedized analyzer, that is cost-effective, easy to use, and reliable.

Features and benefits:

  • Powerful 4W X-ray tube, 200 µA current (max), optimized beam settings
  • Tight geometry for exceptional LODs and high analysis throughput
  • Patent-pending automatic barometric pressure correction that adjusts calibration as needed for more accurate analysis of light element.
  • Lightning-fast data acquisition for faster testing time
  • Floating Point Processor: Provides more calculations in less time, and leverages more advanced calibration algorithms
  • Integrated Bluetooth® for data input and output available in most countries
  • Integrated wide area heat sinks throughout the DELTA body for high power use in extreme temperatures
  • Analysis indicator lights visible from 360° to help ensure safe use
  • Advanced colortouch LCD screen for clarity, brightness, responsiveness, and energy efficiency for indoor/outdoor use
  • Accelerometer technology puts the unit into sleep mode to save energy when not in use; logs impacts for tool management
  • DELTA PC Software for enhanced data analysis, calibration modeling, and optional closed beam workstation operation
  • USB interface port for high-speed downloads and seamless PC control
  • Ergonomic rubberized handle for enhanced grip
  • Docking Station and Hot Swap Batteries



Mineral Exploration

DELTA series analyzers enable:

  • Due diligence during property acquisition
  • Qualitative chemistry of rock, chip, soil, and sediment samples at the early regional reconnaissance and mapping stages
  • Quantitative data during first pass regional soil, sediment, till, and trenching stages
  • Immediate identification of mineralized trends and anomalies, definition of drill targets, extension of soil sample lines
  • Adaptation of sampling and mapping programs in real-time to maximize exploration budgets
  • Pre-screening of samples to maximize efficiency of off-site laboratory testing
  • Increasing sample density in the most prospective areas
  • Analysis of air core, RAB, RC and diamond core samples during the drilling phase as the samples come out of the ground

Mining and Metallurgical Processing

Portable XRF can provide productivity increases through on-site, immediate geochemical analysis results. Make decisions on the spot.

  • Instantaneous screening of blast hole samples in open pits allows for more efficient movement of ore/waste material by reducing the reliance on the turnaround time from the mine laboratory
  • Field analysis of stockpiles assists rapid blending and feeding to the mill
  • Real-time analysis of feeds, concentrates, and tails allow immediate dosing adjustments to be made in the processing plant
  • Underground grade control can be improved in certain settings by establishing sampling and analysis methodologies that involve DELTA portable XRF. Innov-X XRF's aid the decision making process at the underground face in many underground mines around the world on a daily basis
  • Sample and matrix specific calibrations are usually required for mine-site applications. The DELTA is designed to be very easy to set up and use with multiple calibration models to ensure optimal performance - even for challenging light element (Mg, Al, Si) analysis
