The comparator CHK7-1012 has a communication interface with an external personal computer USB 2.0 and application software for an external PC. At the request of the customer, the comparator can be supplied complete with a laptop or tablet computer with installed software.

It is intended for express measurements in residential and working premises of biologically hazardous levels of electrostatic fields, the sources of which are electrical installations, information display media (computer displays, televisions, slot machines), as well as finishing building materials.

The Ch1-1012 frequency standard is designed for mobile applications with high requirements for dimensions, weight and power consumption as an embedded signal source of high stability in frequency measuring devices and complexes, telecommunication systems, navigation and communication systems. This device can serve as a promising substitute for quartz generators in the development of high-resolution equipment, where the accuracy characteristics of a quartz generator are no longer sufficient.
