The Chauvin Arnoux C.A 6121 machine tester has been designed for testing the electrical safety of machines, in conformity with standard EN60204-1, parts 19-1 to 19-5.

Its worksite case is hardwearing, but also easy to carry to your measurement site. Its interface, simple to use, gives you very rapid access to all the main functions of the instrument. Its optional accessories allow it to be adapted to all specific environments.

Sturdy and portable, the C.A 6121 is the tool of the machine directive. Mandatory since 1995, this directive, whose aim is to guarantee the safety of users, imposes four types of electrical tests. To facilitate bringing into conformity new or installed machines, Chauvin Arnoux has grouped together all the necessary measurements, in a unique “all terrain” instrument.

Equipped with a particularly clear display, the C.A 6121 surprises by its ease of use. Besides its measurement capacities and the variety of its accessories, the instrument also  has a comfortable memory and an RS232 output for a paper printout, or for exploitation on PC.
