DELTA Consumer Safety & RoHS Handheld XRF Analyzers allow for testing large quantities of consumer & electronic products anywhere, anytime. Get simple, fast, nondestructive regulatory compliance screening for Pb, Cd, Hg, Br & more. Use for ASTM Method F2617-08, HR4040, CPSC, CPSIA & more.
When it comes to safety, there are no compromises. The DELTA handheld XRF is a key part of any reasonable testing program for general conformity certification (GCC).

DELTA Consumer Safety Handheld XRF analyzers are used for rapid product and component screening to monitor compliance with CPSIA, RoHS, WEEE, EN71-3 and other regulations. They provide fast, accurate answers to take action. Already new elements, including nickel (Ni), are being considered for addition to the existing regulation timelines. The DELTA measures these and more too. Olympus follows the development of global regulations closely to ensure our analyzers and technology stay ahead of the regulatory requirements.

Government agencies are responsible for protecting the public from unreasonable risks, such as toxicity and pollution associated with consumer products and electronics. Due to their fast, nondestructive and on-the-spot screening capabilities, Olympus handheld XRF analyzers have been chosen repeatedly by the US Customs, the FDA, the EPA, the DOE and international customs agencies when it comes to rapid screening analysis of regulated toxic elements such as lead (Pb) and cadmium (Cd).


The DELTA series handheld XRF analyzers are configured with powerful miniature X-ray tubes, Si-PIN, or highly advanced Silicon Drift Detector (SDD) detection, specialized filters, and multi-beam optimization for the ultimate in XRF field analysis.

Traceable documentation makes the DELTA the ideal tool for your Reasonable Testing Program (RTP). |
The DELTA automatically determines sample type (polymer, alloy or mixed) and optimizes measurement conditions accordingly. It recognizes non-homogeneous ("mixed") samples to alert the operator, which is critical for error-free operation. The DELTA also distinguishes Pb in the surface or in the substrate.

The New Generation DELTA Handheld XRF Analyzers are ergonomically advanced with a forward looking design incorporating the latest in electronics, components, and software technology.
The newly available DELTA X-act Count Technology can provide even better sensitivity and precision in faster time for more materials than before. Throughput is increased with the same or better precision in half the time for most elements.
