• The datalogger F842 has been designed in order to be connected to standard industrial sensors like 4-20mA, 0-5V and 0-10V.
• Acquisition in industrial environments.
• Acquisition where a combination of large memory and low power is required.
• Acquisition situations requiring flexibility and control of external devices or sensors by the datalogger.
• The datalogger can be employed outdoor and indoor.
• The 10-bit resolution plus 1 bit of autoranging guarantees a resolution 8 times higher than 8-bit products commercialised by competition, making the use of F842 ideal for detailed acquisition.

• The difference between F842 and other dataloggers is simple:
  F842 allows you to write and load a procedure (sort of program) that will be executed at sampling time.
  For example: you need to start a pump once a day and measure its pressure after a certain amount of time.
  Yes, you can do that by using the relay output and the built in delay function.
  The procedure for the above is one of the examples included with the software.
  The F842 has a powerful set of commands that allows you to manage effectively your data acquisition challenges.
