Clearly define testing requirements

Focus of testing items: ROHS testing covers heavy metals and organic compounds, and the testing focus varies among different enterprises. Enterprises producing electronic components and metal products have higher requirements for the detection accuracy of heavy metals such as lead, mercury, and cadmium; For enterprises producing plastic and rubber products, the detection of organic compounds such as phthalates is a key focus, and the detection focus needs to be determined based on the types of harmful substances that may be contained in their own products.

Detection quantity and frequency: Small electronic processing plants have low detection quantity and frequency, and can choose economical and practical detectors; The inspection and measurement of large-scale electronic and electrical equipment manufacturing are large and frequent, requiring consideration of equipment with fast detection speed and the ability to adapt to high-intensity work.

Application scenario requirements: If fine testing is mainly conducted in the laboratory, high precision and stability requirements are placed on the instrument, and desktop testing instruments are more suitable; If real-time monitoring is required on the production line or quick judgment is needed on the incoming inspection site, portable or handheld detectors have more advantages.

Assess instrument performance

Detection accuracy: The ROHS directive imposes strict restrictions on harmful substances, such as a limit of 0.01% for cadmium and 0.1% for lead, mercury, etc. This requires the detector to have sufficiently high accuracy. For example, the DX-520L of the German spectrum instrument uses a high-precision resolution of 127 ± 5eV, which can accurately detect extremely low levels of harmful substances.

Detection speed: In fast-paced production environments, detection speed directly affects production efficiency. Some advanced detectors can detect a single sample in as fast as 25 seconds and support multi-element synchronous analysis, which can meet the needs of large-scale production enterprises.

Stability and reliability: The stability of the instrument determines the consistency and repeatability of the test results. High quality detectors are designed and manufactured using high-quality components and advanced technology to ensure long-term stable operation. For example, the equipment of Depu Instrument has been validated in industrial scenarios, continuously testing the same standard sample for a long time with minimal data deviation.

Pay attention to the convenience of operation and software functions

Operation interface: The ideal ROHS halogen detector should have a simple and intuitive operation interface, such as the 7-inch touch screen of the detection instrument of Depu Instrument, which adopts the "one click detection" mode. Newcomers can operate independently after a short period of training.

Software Function: Intelligent testing and analysis software should have automatic spectral line recognition function, support simultaneous qualitative and quantitative analysis of multiple elements, generate clear and intuitive detection reports, and can also be integrated with enterprise ERP systems to achieve automatic data transmission and management.

Considering safety performance: ROHS halogen detectors often involve radiation sources such as X-rays. The instrument should adopt a full path radiation protection system, combined with multiple safety protection designs. For example, the detection instrument of Debu Instrument uses a software and hardware dual safety interlock mechanism, sets up automatic safety protection switches, and comprehensively reduces the risk of radiation leakage.

Understand after-sales service

Technical consultation and selection guidance: In the early stages of purchase, professional technical consultation and selection guidance are crucial. Manufacturers should be able to recommend the most suitable product model tailored to the customer's business characteristics, testing needs, and budget.
