Data Transmitter 795 1 Introduction Thank you for choosing an MJK Data Transmitter 795. A great effort has been put into developing a product, which complies with all demands. All settings, alarms and logged data can be read in the display, from easy to use functionnal menus. MJK Data Transmitter 795 can be supplied in versions that communicates via a built-in GSM modem or telephone modem, or in versions for radio modem.
Data Transmitter 795 1.3 MJK-Link™ The Windows based program MJK-Link™ can be applied to monitor one or several MJK Data Transmitter 795. Via a PC with modem it is possible with MJK-Link™ to read values, modify setpoints and read datalogger for e.g. storm flow values. All settings in Data Transmitter 795 can be implemented via MJK-Link™. Explosion hazardous areas MJK Data Transmitter 795 is not approved for use in explosion hazardous areas.
