Restriction of hazardous substances (RoHS)
The European Union RoHS Directive and subsequent regulations
introduced in member states and other countries limits the use of six
hazardous substances used in the manufacturing of electrical and
electronic equipment.
Currently, monitoring and control instruments do not fall within the
scope of the RoHS Directive, however Hach Lange has taken the
decision to adopt the recommendations in the Directive as the target
for all future product design and component purchasing.
