Skyray Explorer 3000 – Handheld RoHS XRF Analyzer

Model: Explorer 3000
Brand: Skyray Instruments
Product Type: Handheld X-Ray Fluorescence Analyzer
Primary Application: RoHS and hazardous-substance screening

Overview

The Skyray Explorer 3000 is a portable handheld X-ray fluorescence, or XRF, analyzer developed for rapid, non-destructive screening of hazardous substances in electrical products, electronic components, consumer goods, packaging materials, toys, batteries and industrial materials.

The instrument performs elemental analysis directly on solid, liquid and powder samples with little or no sample preparation. Its compact handheld design supports both on-site inspection and laboratory use.

According to the brochure, the Explorer 3000 uses an energy-dispersive XRF analytical method and can measure elements with atomic numbers from 12 to 92, covering magnesium through uranium. It supports simultaneous analysis of up to 40 elements, with typical measurement times from 1 to 60 seconds.

Applications

• RoHS compliance screening

• Electrical and electronic manufacturing

• Electronic-component inspection

• PCB and solder-material testing

• Incoming raw-material inspection

• Waste electrical and electronic equipment recycling

• Packaging-material verification

• Toy and children’s-product testing

• Battery-material screening

• Consumer-goods inspection

• Machinery manufacturing

• Metal-alloy identification

• Supplier quality verification

• Third-party inspection

• Field and laboratory elemental analysis

The brochure specifically highlights applications in electronics, WEEE recycling, machinery processing, toy production, packaging manufacturing and consumer-product inspection.

RoHS Screening Capability

The Explorer 3000 is intended for rapid screening of restricted substances associated with RoHS compliance.

Typical screening elements include:

• Lead, Pb

• Mercury, Hg

• Cadmium, Cd

• Chromium, Cr

• Bromine, Br

Important: handheld XRF normally measures total elemental concentration. It does not directly distinguish:

• Hexavalent chromium from total chromium

• PBB from total bromine

• PBDE from total bromine

Positive or borderline screening results may require confirmatory laboratory analysis.

Detectable Element Range

The brochure lists fast analysis for elements including:

• Mg, Al, Si, P and S

• Ti, V, Cr and Mn

• Fe, Co, Ni, Cu and Zn

• Ga, Ge, Zr, Nb and Mo

• Ru, Rh, Pd and Ag

• In, Sn, Sb and Hf

• Ta, W, Re and Pt

• Au, Pb and Bi

The stated overall elemental range is Mg to U, subject to calibration, sample matrix, measurement time and detector configuration.

Waterproof and Dust-Resistant Design

The brochure describes the Explorer series as waterproof and dustproof for use in demanding industrial environments. The exact IP rating should be confirmed before publishing a specific ingress-protection claim.

Software Functions

The Explorer software provides two principal operating modes:

Operator Mode

Designed for routine daily testing.

• One-step operation

• Simplified workflow

• Suitable for production and incoming inspection

• Reduces operator training requirements

Expert Mode

Designed for experienced users.

• Advanced analysis functions

• More detailed method control

• Suitable for technical investigation

• Supports deeper result interpretation

Safety Features

The brochure lists several operator-protection features:

• Automatic X-ray tube shutdown when no sample is detected

• Thick steel construction with lead shielding

• Rubber radiation shield to reduce scattered X-rays

• Manual safety interlock

• Multi-colour instrument-status lights

Status indicators include:

• Green for power-on or standby

• Red flashing during measurement

• Yellow flashing when a fault is detected

All XRF operation must comply with applicable radiation-safety, licensing, registration and operator-training requirements.
