Data loggers are designed for record of voltage signal 0-5V (optionally 0-10V) or current signal 0-20mA. At the same time state of binary signal can be recorded. Values are stored to a non volatile electronic memory. Data transfer to the personal computer for further analysis is performed via USB, RS232, GSM or Ethernet interface by means of a proper adapter.

Main applications of data logger:

*Distant places with no electric power
*Long term field measurement
*Research and development
*Laboratories
*Technological processes
