  • RTU & ASCII protocols.

  • Data automatically sent securly to our cloud server, no need for any dialup.

  •  RS485 & RS232 communication.

  • Sample up to 2 analysers / sensors, each with above  combination.

  • Connects to our Data Management System on the cloud via Wifi, GPRS,3G, or 4G.

  • Total of 20 channels may be sampled.

  •  Setup alarm levels for each channel .

  •  Set alarm for each channel on status value.

  • Change sample, store and transmit rate to the cloud during alarm state.

  •  Reset cumulative  channel counter.

  • 2 Factorisation calculations on each channel.

  • Ability to run on solar and battery with option of having  "low power periods" for the modem, for example during the evening. This data is stored during this period, then sent when back  when normal power mode is resumed.

  •  Display data on the cloud using the various applications; 

*  Mobile application on iOS and android

*  Windows and apple Mac desktop application.

*  Reports application for displaying advanced reports from a single gateway   to a complete network.

*    Web portal for display on browsers.

*  HTTPS API so data can be inserted into your own package.
