The Metrohm 7A501C safety insulation tester, originally designed for use in hazardous areas - such as mines and petrol sites.

The Metrohm 7A501C safety insulation tester was originally designed for use in hazardous areas - such as mines and petrol sites. Whilst this tester does not qualify for ATEX approval, safety officers should evaluate the risks of failing to perform adequate electrical safety testing. In an environment where ATEX 94 applies, the purchase of a new 7A 501C to carry out essential electrical safety tests should be subject to a risk analysis by the site safety officer. As such this product is only available for sale where the intended use is outside the EU. NOTE: BS1259 is now obsolescent and has been superseded by BS5501. Under BS1259 the tester by itself was approved whereas under BS5501 approvals also consider applications of the tester.
